Bug 216194
To me it looks that this DSDT doesn't have the needed properties, so ASUS would need to add those in a BIOS update. Please contact them to get the firmware fixed. https://github.com/torvalds/linux/blob/d7227785e384d4422b3ca189aa5bf19f462337cc/sound/pci/hda/cs35l41_hda.c#L319 On Windows, it functions perfectly. I believe we should wait to hear from Cirrus devs. Other platforms with this amplifier must have this information added to BIOS specifically for Linux as it's otherwise not discoverable information. Let me attach a dsdt from a platform that did it right to demonstrate. These values aren't necessarily correct for your system, ASUS needs to put the right ones in for your system.

snippet from DSDT on another platform that works properly
I understood it. Why this is not necessary for the Windows driver baffles me. I don't know the details either but if I was going to guess you could specify this type of info in the INF for Windows. Maybe poke around the Windows driver for similar info for your system. If it is indeed in the INF maybe a quirk for this system to set device properties is doable from that information. The "proper" solution is to have it in the BIOS though. Unfortunately, ASUS said they don't provide tech support for Linux. Created attachment 301529 [details]

I have attached a two of the INF files shipped with Windows. The codec one has many stuff in it that seems to relate to something that could be in DSDT. Does it look familiar?

It doesn't directly match anything like the DSDT information I referenced above (no mention of word GPIO or index). Maybe you should start with the snippet I shared and try to set up a quirk for your system using that information as a reference from a working system. It all depends on whether the design is different for this OEM or not from the one I shared the snippet from. > I suppose the AmdDMIC ones could help with the mic not working as well. If the DMIC isn't working, I would start out with adding the platform to https://github.com/torvalds/linux/blob/master/sound/soc/amd/yc/acp6x-mach.c#L47 and make sure that you have the right driver matching it selected in your kernel config.

Those INFs appear to have no meaningful information. Is there anything I missed? I think it's worth raising this discussion on the mailing list for your case. I'm not familiar with the LKML. Which mailing list should I use? linux-audio or alsa-devel? BTW it appears that another laptop model has a similar issue. https://lore.kernel.org/all/20220811053950.11810-1-faenkhauser@gmail.com/T/ From my perspective this is still a BIOS bug. The OEM /should/ be populating the relevant _DSD. But for this discussion on a quirk and what it should be, I suggest alsa-devel ML. I'm pretty sure you'll at least be able to get Cirrus guys attention. Created attachment 301611 [details]

ACPI dump from Lenovo Legion 7i Gen7
The Lenovo Legion 7i Gen 7 also has non-working sound with the CSC3551. I don't have a Lenovo Legion 7i Gen 7 myself, but I've been working with someone who does. I just attached the ACPI dump and dmesg they shared from their system. The Intel HDA early patching method was used to apply the CSC3551 i2c quirk. Here is their alsa-info as well: http://alsa-project.org/db/?f=0be0a7575b5bcc9534f5e301194db6f31f614eba Here's the relevant section from the dump: Scope (_SB.PC00.I2C2) { Name (I2CN, Zero) Name (I2CX, Zero) Name (I2CI, 0x02) Method (_INI, 0, NotSerialized) // _INI: Initialize { I2CN = SDS2 /* \SDS2 */ I2CX = 0x02 } Device (SPK1) { Name (_HID, "CSC3551") // _HID: Hardware ID Name (_UID, One) // _UID: Unique ID Name (_SUB, "17AA3874") // _SUB: Subsystem ID Method (_INI, 0, NotSerialized) // _INI: Initialize { If ((SPID == Zero)) { _SUB = "17AA3874" Return (Zero) } If ((SPID == One)) { _SUB = "17AA386F" Return (Zero) } } Name (GPIB, ResourceTemplate () { GpioIo (Exclusive, PullDown, 0x0000, 0x0000, IoRestrictionOutputOnly, "\\_SB.GPI0", 0x00, ResourceConsumer, , ) { // Pin list 0x0027 } GpioIo (Shared, PullUp, 0x0064, 0x0000, IoRestrictionInputOnly, "\\_SB.GPI0", 0x00, ResourceConsumer, , ) { // Pin list 0x0026 } GpioInt (Edge, ActiveBoth, Shared, PullUp, 0x0064, "\\_SB.GPI0", 0x00, ResourceConsumer, , ) { // Pin list 0x0026 } }) Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { Name (IBUF, ResourceTemplate () { I2cSerialBusV2 (0x0040, ControllerInitiated, 0x000F4240, AddressingMode7Bit, "\\_SB.PC00.I2C2", 0x00, ResourceConsumer, , Exclusive, ) I2cSerialBusV2 (0x0041, ControllerInitiated, 0x000F4240, AddressingMode7Bit, "\\_SB.PC00.I2C2", 0x00, ResourceConsumer, , Exclusive, ) }) Return (ConcatenateResTemplate (IBUF, GPIB)) } Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0F) } Method (_DIS, 0, NotSerialized) // _DIS: Disable Device { } } } I wonder if updating the DSDT to include the missing properties would the way to go for the initial testing: https://wiki.archlinux.org/title/DSDT#Find_a_fixed_DSDT All assuming that the example of working properties would even be valid. Perhaps the values needed are hardcoded into the drivers (or the tunings)... Another possibility, is that the drivers assume default values if the relevant values are not in the DSDT.

Initial but dangerous support for Lenovo Legion 7i Gen7. Use at your own risk.
I went ahead and tried hard coding some values. This is against kernel 5.19.4 and sound does partially work.
It's all rather hacky, but you can make changes under the 'csc3551:' label in 'sound/pci/hda/cs35l41_hda.c'
But I do get left channel audio out of the right speaker. However, as a warning, I suspect this is fine, but I can't guarantee it. I get this potentially ominous message in dmesg:
[ 412.976460] cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Amp short error
I think this is probably really easy to fix (just need to adjust some of the more obvious values I'd guess), but I don't have a lot of time today so I'm sharing it in case someone else wants to play with it.
If you don't have the same model of laptop as me, don't forget to add a quirk for your laptop under 'sound/pci/hda/patch_realtek.c'

lenovo-7i-gen7-0.0.1.patch
This patch gives me full working sound on the Lenovo Legion 7i Gen 7 (16IAX7). It's for 5.19.4. I suspect it's fairly safe, but use at your own risk.
As it is, it won't be accepted into the kernel (and nor should it be). But it shows you can get sound working without the values in the DSDT.
I wonder if Cirrus Logic has plans to support quirks for different laptops, etc in their driver?
One big caveat, is that when resuming from sleep/hibernate, you will no longer have sound. Does anyone know if this is true in general for CSC3551 based systems? I know it's true for the CLSA0101 (which is supported by the same driver) and that a patch to fix that is coming eventually according to Cirrus Logic.
XiaoYan Li, this might work for you. You'll just need to add a quirk line for your specific model of laptop.

You can certainly do a cleaner quirk from your existing patch that can potentially be mainlined and discuss it. You'll want to add a DMI match table and just run that new code when your system is detected. I reached out to the submitter of this patch to see if there is already some work to enable device specific works or at least plans for it: https://www.spinics.net/lists/alsa-devel/msg146157.html (In reply to Mario Limonciello (AMD) from comment #25) > You can certainly do a cleaner quirk from your existing patch that can > potentially be mainlined and discuss it. You'll want to add a DMI match > table and just run that new code when your system is detected. Looking at the DMI match stuff, it seems fairly straight forward. If there are not even plans to enable quirks for machines that lack the otherwise necessary _DSD properties, it's something I'd be willing work on. Created attachment 301704 [details]
lenovo-7i-gen7-0.0.2.patch
No change in functionality, but cleaned up the original patch a bit.
I'm also setting the GPIO reset pin correctly (or at least less incorrectly) for each amp chip resulting in no longer seeing this message: "Reset line busy, assuming shared reset"
At least another model was reported to have the same missing nodes (bug 216446). So if your quirk methodology ends up working it would be good to get data for both models in place. Unfortunately, Cirrus Logic got back to me and stated that what I'm doing isn't a great idea as utilizing the wrong settings could potentially physically damage your speakers. I hadn't updated on this sooner to see if they'd follow up with me, but so far they have not. If you have an unsupported model, your best bet is to ask the laptop vendor to update their BIOS with this information. Perhaps if a vendor gets enough requests, they may actually even do it. I'm still holding off before I ask Lenovo, but if I don't hear back from Cirrus logic within the next 1-2 weeks, I'm going to give it a shot. In my experience, Lenovo has been pretty uncooperative with this sort of thing when it comes to models that aren't explicitly Linux supported so I won't be holding my breath. Thanks. I think that's enough of a reason that we should close this issue. Anyone affected by this should report the issue to the OEM to get fixed in BIOS. I opened a ticket with Asus for the UM3402Y and they've replied with "Our team has advised that we will forward this information to our senior team for review for future design consideration once we start supporting Linux OS." Time to sit back and wait, but at least it's hopeful. Created attachment 303151 [details]

Currently, Nvidia drivers don't work with 6.2*, but 6.2* does allow you to increase your refresh rate to 165 Hz instead of being stuck at merely 60.
So this patch could be useful if you have no gaming or CUDA work worked planned in the near future. Plus, I'm getting ahead of 6.2* support.
NOTE: This is still use at your own risk. However, I have it on good word that after several months of Linux usage nearly absolutely everyday, there are no issues.

Plus, I'm getting ahead of 6.2* support. As a "cleaner" patch perhaps you can do it as an DSDT/SSDT patch that is loaded by your bootloader (IE GRUB) or contained within the initrd. It would also illustrate exactly what the OEM needs to put into their BIOS for them to fix it properly. Unfortunately, I don't have exactly what's needed for this model of laptop. The values are guessed and there are several optional values that can be set (but of course, aren't). MIGHT be useful as an example? I've already tried the approach with doing the DSDT approach and even had some success this way with the guessed values... But one speaker would keep going out with an "Amp Short" error in dmesg. My patch behaves somewhat differently than what we get with the DSDT entries since it's based on an older version of the cs35l41 driver and so doesn't have that particular issue for whatever reason. I suppose I could narrow it down to which part is results in this issue, but haven't had the time. My current patch is the best that can be done for the Lenovo Legion 7i Gen 7, at least for now.

Does this patch also work for the Legion Slim 7i Gen 7 (16IAH7)? It could be adapted to work for it by adding a quirk. That being said, the slim version likely needs different settings. Using wrong settings could damage the laptop. How do I know this patch is fairly safe on the non-Slim Gen 7 Legion 79? Because it's been used daily for months without issue.

The previous patch included a fix that is now already in rc3, preventing the old 6.2.0-rc1 patch from not applying cleaning to rc3. This fixes that.

Here's what I tried so far: - downloaded kernel version 6.2.0-rc3 from kernel.org - used the endeavourOS default .config and made sure the config options you mentioned are set (they already were) - applied your patch and compiled the kernel => unfortunately still no working audio I tried the same thing with a small modification to your patch, changing the "Legion 7 16IAH7" in line 128 to "Legion S7 16IAH7" since I wasn't quite sure if this was a typo (?), but still no success after recompiling the kernel Am I missing something? I'm also not sure if I just got some configs (alsa/whatever) wrong, I tried a bunch of things with no success yet. I also noticed that the output of `dmesg | grep error` still lists: [ 0.009609] [Firmware Bug]: TSC ADJUST differs within socket(s), fixing all errors [ 5.349307] Serial bus multi instantiate pseudo device driver CSC3551:00: error -ENOENT: Error requesting irq at index 0 [ 5.351682] Serial bus multi instantiate pseudo device driver: probe of CSC3551:00 failed with error -2 [ 5.964098] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 and I'm not sure if the second and third line here imply that the fix in fact didn't work?

It seems it there's a problem getting the hardware going. This is a separate issue that occurs before any of the coded added by my hacky patch can even be run. Unfortunately, I don't know what it's happening. Do you get the same kind of error with the stock kernel (assuming the stock kernel is recent enough for CSC3551 support)? What version is your stock vendor kernel BTW? I see from your alsa-info, that the stock vendor kernel is 6.1.4-arch1-1 That's definitely recent enough. What messages relating to CSC3551 do you get in dmesg there? If it's able to pick up the hardware... maybe there's a bug in 6.2 that affects you hardware. The dmesg on the stock kernel contains the same 2 errors regarding "CSC3551". I came across this bug where people seem to relate it back to cs35l41, I've got no clue about this stuff, but maybe you can make sense of it... https://bugzilla.kernel.org/show_bug.cgi?id=215993 One comment also links to this: https://github.com/CirrusLogic/linux-firmware/tree/main/cirrus/cs35l41 although I'm not quite certain if that means it's already in the linux kernel by now or not. I might be completely on the wrong track here as I don't understand much of any of this, I'll try and look further into it tomorrow as much as I can but I doubt I'll find solutions completely on my own. I don't take your further help for granted and really appreciate what you've already done for me, however I'd be very grateful if you could maybe take a look at it. Thank you in advance!

Sadly, this is probably just for Lenovo's Linux supported laptops. Though it means that they do have some know-how on how to add the relevant DSD intros into the BIOS. I'm not really sure what's going on here either... Maybe there's a way you can report this issue to Cirrus Logic? Most likely, your laptop is missing the DSD entries, so once this is fixed, you'd still need a workaround like my patch. Cirrus Logic might be interested in fixing another corner case. On a tangential note... The latest BIOS version for my laptop is from July. I think I've had it since September? Weird that Lenovo hasn't had any updates for it, but maybe we'll get lucky? Make sure you have the latest BIOS. Even if updating doesn't add DSD entries (probably not), there is a _slight_ chance it could fix your current issue.

This is a very much use at your own risk scenario. These are guessed values that have worked for the Legion 7i Gen 7 for an extended period of time without issue.
Sounds like the Intel based 7i has been working (can anyone followup?) so this could be okay too. If you encounter issues which may include but is not limited to distorted sound, loudness, and perhaps "amp short" errors in dmesg, stop using this patch for your slim.

What do you think could be the reason? Thank you for all your work on this issue. Are you sure none of your sound is muted? This is something I've seen many times over the years. Try alsa-mixer maybe? Try the sound settings for your laptop. Maybe something (like the output device) is misconfigured? The output from the patched kernel strongly suggests it's working (though there's likely more related dmesg output than what you've shared which could be helpful). In case it wasn't clear, I have the exact same model of laptop as you so it should definitely work.

dmesg on patched Legion 7 16IAX7
Thank you for your quick reply. Here is the output from dmesg on the patched kernel (uname -sr --> Linux 6.2.1-arch1-1-legion7). I tried speaker-test and the tests from KDE's audio settings, with both intel and nvidia cards, to no avail. Alsamixer shows nothing muted except for S/PDIF (unmuting it changes nothing). When I try to play some sound, the system tray GUI volume indicator moves (showing changes in output volume),
I use wireplumber, but this should be immaterial: in my understanding speaker-test is more low-level as it interfaces directly with ALSA.

lenovo-7i-gen7-sound-6.2.0-rc3-0.0.5b-001.patch
Found the problem. Jacopo and I have slightly different revisions of the same laptop and therefore have different subsystem ID's.
Here's an updated patch that adds this revision's subsystem ID to use the quirk.

Now it works, this is the best! There's a little "click" sometimes when a sound starts playing, but I guess that's just a software glitch, as it goes away when trying to reproduce it. Thank you Cameron, you really helped me! See if the click occurs with all software. When it happens, try "dmesg -T" (to get a timestamp) and see if any messages line up. I don't recall that happening to me, but I could just be tuning it out. What I think might be happening... is that when there hasn't been any audio output for a while, the speakers/amp chips go to sleep and have to be woken back up. In such situations, I notice there's a small delay in audio output starting up again (probably a bit less than a second, but I've never tried to time it) so that could it. If that's the case, you'll likely see some output in dmesg corresponding to the CSC3551's being woken back up. If you notice one speaker going out (or both), keep an eye out for "amp short" errors in dmesg. When those happen, you'll temporarily lose sound in the affected speakers... Eventually it will recover. When this is an issue, it's more likely to occur at high volumes (so worth looking for!). There's no documentation in the code as to what these errors mean... but I think what's happening is that the amp chip has determined that whatever it's sending to the speaker is perhaps out of bounds so that's not good and probably you would want to avoid using the patch until we can figure something out. So definitely test this out. If you're able to play some music at a high volume for a couple of minutes without issue, I think you're safe from this particular "amp short" issue. But this is very encouraging news! I'm glad we got this working for you! I think it's ridiculous that in 2023 we can't just have working sound in Linux on x86. I remember buying an ISA Soundblaster 16 in 1999 to ensure sound would work under Linux then having to pass parameters to the module such as the ioport, etc. We've come so far since then, but some vendors are still so obtuse about these things.

lenovo-7i-gen7-sound-6.2.0-rc3-0.0.5b-002.patch
This patch theoretically supports the following models:
+ SND_PCI_QUIRK(0x17aa, 0x3874, "Legion 7 16IAX7", ALC287_FIXUP_CS35L41_I2C_2),
+ SND_PCI_QUIRK(0x17aa, 0x386f, "Legion 7 16IAX7", ALC287_FIXUP_CS35L41_I2C_2),
+ SND_PCI_QUIRK(0x17aa, 0x3803, "Legion 7i slim 16IAH7", ALC287_FIXUP_CS35L41_I2C_2),
+ SND_PCI_QUIRK(0x17aa, 0x3856, "Yoga Slim 7 Carbon 14ACN6", ALC287_FIXUP_CS35L41_I2C_2),
+ SND_PCI_QUIRK(0x17aa, 0x3877, "Legion 7 slim 16ARHA7", ALC287_FIXUP_CS35L41_I2C_2),
The Lenovo Legion 7i Gen 7 16IAX7 seems pretty safe (and has had by far the most testing).
That being said, all support provided by this patch is USE AT YOUR OWN RISK. Different models of laptop theoretically have different values (that should be provided via the DSD table in the BIOS). These are guessed values that work for the 16IAX7 and possibly others. I can't make any guarantees.
If you have problems with your sound, overly loud volume, distorted sound, "AMP short" errors (see below), back out the patch and update this bug with your feedback (giving your alsa-info)
If you get "AMP short" messages in dmesg, it's probably wise to back out the patch as I suspect prolonged usage could result. To test for this, just play some music out a very high volume for a few minutes. You may notice one or both of your speakers going out (and you'll see "AMP short" messages in dmesg). If this happens, back the patch out.
With "AMP short" errors, once audio output has been stopped for probablly 5+ minutes, the affected speakers will "recover", but eventually they'll fail again. Just because they might start working again doesn't mean there isn't a serious problem. Just back out the patch and provide feedback.
If you don't get any sound at all... Provide your alsa-info and your full dmesg output. If you see a message such as "Serial bus multi instantiate pseudo device driver CSC3551:00: error -ENOENT: Error requesting irq at index 0", this is an issue that occurs before my patch. There's an issue with the cs35l41 driver where it's not able to detect the CSC3551's on your model of laptop. Reporting this to Cirrus Logic may help and AFTER that issue is fixed... You may still need my patch.
If the patch works, please provide feedback with your alsa-info. With all the info, my hope is that we'll have an eventual "safe list" of laptop models for this patch.

dmesg + alsa-info
Update: sound in general still works great (the nVidia sound card does not work but I think that's an alsa config issue). Clicks happen upon opening sound related apps like spotify but leave no trace on dmesg.
However, it appears that some errors are triggered in cs35l41_hda.c (functions: static int cs35l41_apply_calibration, static int cs35l41_smart_amp):
[ 6.940102] cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Cannot Write Control: CAL_AMBIENT - 1
[ 6.940971] cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Cannot Initialize Firmware. Error: 1
Not really an issue, I played loud music without speakers going out/short amp errors.
As a suggestion since this patch isn't likely to be accepted by the Cirrus driver maintainers in it's current form it might be best to open up a central place for you to work with people on it and iterate rather than this kernel bug tracker. Maybe like a personal Github repo? Yeah, those errors are expected. I get the same. It's due to the hackish nature of the patch. I think the Nvidia sound is something that needs an external monitor to work (ie, via HDMI or displayport). I'm a bit concerned by the clicks though... But unsure if that problem is serious.

I looked them up and they produce speaker systems of all kinds, from laptop systems to bluetooth speakers, and so I wonder if they would be more forthcoming on the appropriate DSD info or verbs to send? Just a thought, thank you for all you do, Blake Lee No, they can't help here. The values are needed by the Cirrus Logic amplifier chips, and the values are specific to the model of laptop. These values depend on the type and setup of the speakers, and these details are largely unique to the model of laptop. Values that are way out of range relative to your model of laptop can potentially cause physical damage. This is why Lenovo needs to do this. Only they have this information about their own laptop designs. For the Lenovo 7i Gen 7, these values seem completely safe. No issues have developed since August or September (I forget which) since the initial version of the patch was released. I'm hoping these values that I've guessed are largely conservative to avoid as much risk as possible, but I really have no idea and this is why I'm clear this is a use-at-your-own-risk situation.

I guess it's too recent to receive any feedback on this model :O Long story short, I tried n+1 combinations of possible solutions, with n->∞ I even opened a 3ed at Lenovo, https://forums.lenovo.com/t5/Ubuntu/Ubuntu-and-legion-pro-7-16IRX8H-audio-issues/m-p/5210709?page=1#5924344 , that they glossed over with much nonchalance by moving my post to the Linux pile of non working things. My last resource was the wizardry made by Cameron by applying a patch to the lenovo-7i-gen7-sound-6.2.0-rc3-0.0.5b-002.patch, namely adding the pci sound quirk for my sound card SND_PCI_QUIRK(0x17aa, 0x3846, "Legion 7 Pro 16IRX8H", ALC287_FIXUP_CS35L41_I2C_2), hwinfo --sound reports: Model: "Intel Audio device" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x7a50 SubVendor: pci 0x17aa "Lenovo" SubDevice: pci 0x3846 ... Model: "nVidia Audio device" Vendor: pci 0x10de "nVidia Corporation" Device: pci 0x22bc SubVendor: pci 0xffff "Illegal Vendor ID" SubDevice: pci 0xffff Unfortunately, it doesn't work. If you have any idea or guide to rip these DSD info or verbs, I will try to contribute as much as I can. PS, funny thing: I bought the laptop with no OS, so I can't say that my speakers are actually working -.- Thanks a lot to everyone! You're going to need some tools to grab the DSDT table. On Ubuntu you can do this with: sudo apt install acpica-tools # From there you can do: mkdir /tmp/dsdt cd /tmp/dsdt sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.dat iasl -d dsdt.dat # You should then have: /tmp/dsdt/dsdt.dsl Attach dsdt.dsl to this ticket and call it something like dsdt.dsl-16IRX8H so I can take a look at it. If what you need is in there... you need a _very_ simple patch that will be accepted upstream. If not, probably need add support for your laptop to my hacked up patch.. and it will mean I'm definitely going for another brand of laptop next purchase. Scratch that, I see you added your own quirk and it didn't work. You should attach your dmesg and provide the link to your alsa-info. Created attachment 303959 [details]

Hello Cameron, thanks a lot! What I've tested is actually using your patch and added in "patch_realtek.c" section the +SND_PCI_QUIRK(0x17aa, 0x3846, "Legion 7 Pro 16IRX8H", ALC287_FIXUP_CS35L41_I2C_2), gathering the PCI address from hwinfo --sound: Model: "Intel Audio device" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x7a50 SubVendor: pci 0x17aa "Lenovo" <---- this SubDevice: pci 0x3846 <----- This I never used the /sys/firmware/acpi/tables/DSDT . So I have added it here. not sure how to use it though. My alsa-info is here http://alsa-project.org/db/?f=ed0116e9d7235fd5cbece5dccaa589ecad71f534 And my dmesg is https://pastebin.mozilla.org/gjXQOg32 I really admire how much effort you put into helping this community. Thanks again Definitely need your alsa-info link. It's possible this doesn't use Cirrus Logic.

Alsa info without any patch to the kernel
Sorry Cameron, this is the correct alsa-info
Created attachment 303962 [details] attachment-14046-0.html I think this is the relevant section, but I'm also not 100% sure and I'm pretty busy so I can't really check too thoroughly. We do see the "TIAS2781" show in your alsa-info though (but that's just showing your ACPI devices which we already know this is). So far it's not looking like this laptop has Cirrus Logic AMP chips of any kind. From both the DSDT table and your alsa-info. I strongly suspect there's no support for this hardware generally... Googling is turning up nothing.

There's no 3886 in your alsa-info... But might be worth making sure you're selecting the correct audio output device? Maybe "TIA" is the name of the company? I'm not finding anything relevant. If Linux is important to you, I would take advantage of the 30 day return for your money back if all else fails. Sadly, it looks like I will be very much skipping Lenovo on my next laptop (which isn't anytime soon anyway).

Totally not worth the high cost. For the output device I can see I have: Analog stereo duplex Analog stereo output Pro Audio None of them works (headset are working) i will google this tia thing Thx :) from : https://psref.lenovo.com/syspool/Sys/PDF/Legion/Legion_Pro_7_16IRX8H/Legion_Pro_7_16IRX8H_Spec.pdf The laptop specs, in multimedia section it says: Multi-Media Audio Chip High Definition (HD) Audio, Realtek® ALC3306 codec Speakers Stereo speakers (super linear speaker), 2W x2, audio by HARMAN certification, optimized with Nahimic Audio, Smart Amplifier (AMP) (identical to the Legion 7 16IAX7 specs https://psref.lenovo.com/Product/Legion/Legion_7_16IAX7) Yeah, but what is "Nahimic"? We don't get specific model numbers, seems relatively generic. If and when you return it, make it extremely clear it's due to lack of Linux support of course. :) If you find a good gaming laptop that works correctly with Linux that you're happy with, feel free to email me directly. Eventually I'll be on the market for one. :D On 3/15/23 15:17, bugzilla-daemon@kernel.org wrote: > https://bugzilla.kernel.org/show_bug.cgi?id=216194 > > --- Comment #87 from Carlo Francesco (gentuser@gmail.com) --- > from : > > https://psref.lenovo.com/syspool/Sys/PDF/Legion/Legion_Pro_7_16IRX8H/Legion_Pro_7_16IRX8H_Spec.pdf > > The laptop specs, in multimedia section it says: > Multi-Media > Audio Chip > High Definition (HD) Audio, Realtek® ALC3306 codec > Speakers > Stereo speakers (super linear speaker), 2W x2, audio by HARMAN certification, > optimized with Nahimic Audio, Smart > Amplifier (AMP) > > (identical to the Legion 7 16IAX7 specs > https://psref.lenovo.com/Product/Legion/Legion_7_16IAX7) > I wrote this bash script to patch the current kernel with the patch (for archlinux).

These are drivers in progress, and here's the latest version (I think): https://mailman.alsa-project.org/hyperkitty/list/alsa-devel@alsa-project.org/message/ESCCDHAIMYA5LQ44L64ZC4OVTSBRHLKZ/ The problem is that these are ASoC drivers: https://www.alsa-project.org/wiki/ASoC This driver isn't enough to do anything on its own on your laptop I'm afraid. This was exactly the case the cs35l41 drivers (which includes CSC3551 support). A callback was implemented for systems with cs35l41 smart amps so that they audio output would work. Fortunately, one of the Cirrus Logic devs ended up purchasing the Lenovo Legion 7 Gen 6 (AMD version) and wanted his audio to work which helped to grease the wheels I think. I would email the developers and see if they're working on anything or if there are at least plans to implement support. Hopefully we don't end up with a situation where the smart amps are technically supported, but the BIOS doesn't have enough information for them to work, is the case with the Legion 7 Gen 7. So definitely be mindful of your 30 day return period. (In reply to Cameron Berkenpas from comment #92) > Fsck yeah! This is a great find! > > You may have saved Lenovo at least one sale...

Here's a thread where people are expressing their dissatisfaction with Lenovo's support of Linux on their Legion series laptops. Maybe if enough people chime in, they'll take us seriously and we'll get somewhere. I personally don't need/want formalized Linux support... I just want the hardware to work: https://forums.lenovo.com/t5/Ubuntu/Ubuntu-and-legion-pro-7-16IRX8H-audio-issues/m-p/5210709 Thank you all, especially Cameron. His latest patch lenovo-7i-gen7-sound-6.2.0-rc3-0.0.5b-001.patch works just like a charm. But one small note for one who will apply the patch to the latest (currently 6.2.7-arch1) kernel. You need manually copy paste the changes from the patch to the appropriate places of the files modified, cuz with the patch command it places changes in the wrong places. Hi, I've been working with the Legion team on this. I do want to highlight that Linux is not plan-of-record for this platform; but they have been working with the Lenovo Linux team to try and figure this out. This is our busiest time of year with our regular Linux certified platforms so patience and understanding is really appreciated :) The Legion team just forwarded me the patch that is mentioned above as being required. I take it from the post that this is not all of the story and other pieces are missing? Can someone fill me in with as many details/specifics as possible - I want to make sure my asks of the team are as concise and detailed as possible. No promises on a solution at this point - but the Legion team are engaged. Thanks Mark The BIOS needs to include the proper programming for the amplifier for the Linux kernel driver to parse. The patches that have been developed are workarounds with guessed values. This isn't generically safe without knowing the proper values to utilize. What are needed are the settings in the DSD table in the DSDT snippet shared on this ticket (and in my Lenovo forum) post. As Mario mentioned, the values are guessed. I suspect they're mostly safe values, however, I think they're still not quite right (max volume is lower than it should be). So perhaps a few of the guessed values are a bit off and/or some of the values that are optionally needed for the Legion 7i Gen 7i. I believe these are all the properties that the driver can utilize from the DSDT: https://github.com/gregkh/linux/blob/v6.2.9/sound/pci/hda/cs35l41_hda.c#L1322-L1366 Probably the Lenovo Smart AMP CSC3551 drivers are hard coding the values somewhere. You can likely get some a bit of direction/help from Cirrus Logic. I just forwarded you the last email I received from them (you may need to check your spam filter). Even if support doesnt work out for the Lenovo 7i Gen 7, your help is still greatly appreciated! (In reply to Mark Pearson from comment #96) > Hi, > > I've been working with the Legion team on this.

The kernel version is 6.3.2. No amp short error in dmesg. I only added this line to your patch of sound/pci/hda/patch_realtek.c: "SND_PCI_QUIRK(0x17aa, 0x38ab, "Lenovo ThinkBook 16p Gen4 IRH", ALC287_FIXUP_CS35L41_I2C_2)" Great to hear! Just keep an ear out for issues with your sound possibly developing over time. Seeing as people with different models who have had success with this patch haven't reported issues... I wonder if maybe these are just really conservative settings? Under Linux, my sound tends to be more quiet than I'd like it to be, but not bad by any means, and certainly much better than no sound.

I can confirm the sound could output at a acceptable level now at `Lenovo ThinkBook 16p Gen4 IRH` which is same as shuohuili.
Behavior change:
1. after install package named `sof-firmware` in Archlinux, the internal speaker can output sound on up facing speakers (but sound level is very low), but the down facing ones not work. (headphone jack and bluetooth works)
2. after applying the modified patch into kernel v6.3.4, the down facing speaker can output at a right level. (When I tried to adjust volume in Gnome settings, the low and middle volume seems `activate` down facing speakers and high volume `activate ` up facing speakers) (this means the sound level is not adjustable for now, but very funny though, ^_^)
Info:
1. Distro: Archlinux
2. Kernel version: 6.3.4
3. different from the path: (the second parameter has slight different from shuohuili's, this should pick up from alsa-info for specific machine even they may have same devive name, I guess)
sound/pci/hda/patch_realtek.c: "SND_PCI_QUIRK(0x17aa, 0x38a9, "Lenovo ThinkBook 16p Gen4 IRH", ALC287_FIXUP_CS35L41_I2C_2)"
And hope this could be officially fixed up by Cirrus and Lenovo soon <https://lore.kernel.org/lkml/b4c202b2-ab29-e2aa-b141-0c967b2c1645@opensource.cirrus.com/>
Thanks again for all you guys!!! You are amazing!!!

Volume comparison: patched linux/win11
Hi everyone, it occurred to me that since my Legion 7 16IAX7 also has Windows 11 in dual boot, I could test the speaker volume on both systems. This could help with calibration. I played a frequency sweep video on Youtube at 100% volume and used a spectrogram app on my phone, keeping it in the exact same position very close to the speakers.
I superimposed the two screenshots (attached), where red = Linux, green = Windows. The line records the max intensity ever reached at that frequency. Frequencies below 100 HZ should be disregarded as the video wasn't very loud there and it picked up some ambient noise.
I'm running Arch Linux with 6.3.2 patched kernel.

Thanks and good luck! Hi. I tried this; for you to check if I made any mistakes: 1. I cloned the kernel sources and checked out tag v6.4-rc5 2. I copied the source of the drivers to the kernel source tree. 3. I executed "cp /boot/config-`uname -r`* .config". 4, I executed "make olddefconfig" 4. I executed "make menuconfig" and selected "M" for "Symbol: SND_HDA_SCODEC_TAS2781_I2C [=m]" and "Symbol: SND_SOC_TAS2781 [=m]". 5. I copied over the firmware files to /lib/firmware. 6. I built and installed both the modules and the kernel and rebooted.

Note that dmesg does not contain "tas2781" in my case. I'm using Fedora 38. Maybe I have to increase the verbosity of the logging? I guess there is a problem in the quirk
your PCI is clearly stated to be included in the Realtek patch.
your audio Subsystem Id: 0x17aa38bf
The Realtek patch includes it with this line: SND_PCI_QUIRK(0x17aa, 0x38bf, "Yoga S980-14.5 proX LX Dual", ALC287_FIXUP_TAS2781_I2C)
Furthermore the I2C points correctly to the pci device:
i2c-TIAS2781:00 -> ../../../devices/pci0000:00/0000:00:10.0/i2c_designware.0/i2c-0/i2c-TIAS2781:00
I'm not sure why the TAS firmware isn't loaded at the startup.
Anyway, I have just realised that you have 4 audio cards,
snd_usb_audio (card 0)
snd_hda_intel (card 1)
snd_usb_audio (card 2)
snd_soc_skl_hda_dsp (card 3)
can you please add the outputs of:
> # amixer -c 2 contents
> # amixer -c 3 contents
> lspci -knn | grep -i -A3 audio
> sudo dmesg | grep 'hda\|snd\|firmware\|audio'
> pacmd list-sinks
the snd_soc_skl_hda_dsp soundcard actually makes me think.
Since multiple drivers can register the same PCI ID, the snd-intel-dspcfg module exposes an API used by all drivers, and the user can override default choices by setting the dsp_driver parameter. For example:
options snd-intel-dspcfg dsp_driver=1
will allow for the HDaudio legacy driver to be used. This will typically work for speakers and headphones/headsets, but will not allow DMIC capture.
In case, can you try adding this option on fedora's module autoload with something similar to:
sudo tee /etc/modprobe.d/snd-soc-skl-fix.conf <<<'options snd-intel-dspcfg dsp_driver=1'
If it fails, just remove it:
sudo rm /etc/modprobe.d/snd-soc-skl-fix.conf
finger crossed!

Debug outputs of 14IRP8 Part 2
Alright.
Yeah, I have multiple soundcards connected (due to a headset. NVIDIA graphics card and docking station). I figured out (via alsamixer) that soundcard 1 is sof-hda-dsp. Check the attached file for the output of 'amixer -c 1 contents'.
Also, the other commands were piped to the attached file. I don't know what I missed last time but tas2781 is present in dmesg now.
I tried sudo tee /etc/modprobe.d/snd-soc-skl-fix.conf <<<'options snd-intel-dspcfg dsp_driver=1' even with including 'options snd_hda_intel model=alc287-yoga9-bass-spk-pin'. Both options did not make the subwoofers working. But the soundcards were named differently and the mic was not detected any longer.
Just to clarify: I appreciate this help very much :-).

Ok then "options snd-intel-dspcfg dsp_driver=1" did something. At least the correct snd-hda intel driver is loaded. Please keep that options enabled and remove the "options snd_hda_intel model=alc287-yoga9-bass-spk-pin" It won't work for you , because it will quirk SND_PCI_QUIRK(0x17aa, 0x3869, "Lenovo Yoga7 14IAL7", ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN), SND_PCI_QUIRK(0x17aa, 0x3801, "Lenovo Yoga9 14IAP7", ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN), which aren't your Subsystem Id: 0x17aa38bf what stands out to me is : [ 2685.600191] tas2781-hda i2c-TIAS2781:00: tasdevice_prmg_load: Firmware is NULL [ 2685.600196] tas2781-hda i2c-TIAS2781:00: conf_no should be not more than 0 [ 2901.366625] tas2781-hda i2c-TIAS2781:00: tasdevice_prmg_load: Firmware is NULL From a quick search it seems that additional firmwares should be compressed with xz in Fedora.

Unfortunately no lock. What's very strange: I don't have any dmesg entries for tas2781 any longer. Despite booting the same kernel with the same settings. I also didn't manage to reproduce the dmesg entries again.

Ok maybe it's woth adding options snd_hda_intel model=alc287-yoga9-bass-spk-pin, maybe it forces the driver to be laoded. I'm not sure :P No matter what I did, I didn't manage to get the dmesg output for tas2781 any more. I was not able to reproduce this. I have a few further insights however: When setting 'options snd-intel-dspcfg dsp_driver=1', I have three options to choose from in the audio settings: - Analog Surround 2.1 - Analog Surround 4.0 - Analog Stereo Output Setting 'options snd_hda_intel model=alc287-yoga9-bass-spk-pin' leads to a slightly different behaviour in front / rear speakers. Though none of these work. I think the amp is still not activated.

Sure, I thought this had been confirmed: - https://bugzilla.kernel.org/show_bug.cgi?id=217449 - http://alsa-project.org/db/?f=45447739750ff897cdc20fd0e98d4f2055beebdf -> /sys/bus/acpi/devices/TIAS2781:00/status 15 I have the feeling that the /etc/modprobe.d/snd-soc-skl-fix.conf should containt only one line: options snd-intel-dspcfg dsp_driver=1 No other options defined, neither in other files (ie alsa.conf snd.conf or whatever links to an option in snd-hda) It's the only way to force the SOF Linux driver to not be used. This way the snd-hda-intel will run the pci quirk containied in the realtek-patch.c that will try to load the lenovo Firmware (which was not found in your last trial). Thanks! Since this is unrelated to Cirrus Logic amps, probably better to continue this in the Lenovo forums: https://forums.lenovo.com/t5/Other-Linux-Discussions/Power-ACPI-Issues-of-Legion-Pro-7-16IRX8H/m-p/5232492?page=3 The quirk for your model is already in the driver provided by TI? Am I understanding that correctly? If that's the case, the TI devs will likely help you with this.

If your device has a TIAS2781 component inside (http://alsa-project.org/db/?f=45447739750ff897cdc20fd0e98d4f2055beebdf <- note line 71), you can try the following: Install i2ctools first and then run ./2pa-byps.sh with the i2c-bus number where your TIAS2781 is connected. E.g: sudo ./2pa-byps.sh 0 In my case this enabled my subwoofers and the sound was working properly. This change will be included in the kernel in the next couple of weeks / months so no workaround will be necessary anymore. I have the same issue with a new Lenovo Legion Slim 7i Gen 8 - sound works fine through the headphone jack, but the speakers remain silent. I got a bit lost in this thread and the other forum posts I found on this and tried some of the patches that seemed fitting, but to no avail. What can I do? My alsa info is here: http://alsa-project.org/db/?f=b4c4bd602b8bd2851639280076667fd64c08189f This bug has nothing to do with Gen 8.

I can also confirm that Cameron's patch works (with a little adjustment). Following this and other threads on the issue I was able to compile a kernel with working sound. It only took like 10 kernel builds :) For everyone out there without sound here are the steps i took: 1.also-info http://alsa-project.org/db/?f=28c8e557a7baeeeebc911e08f416c051ec702d09 Find out whether you have the TIAS* or Realtek device Find your device (mine looks like this): Codec: Realtek ALC287 Address: 0 AFG Function Id: 0x1 (unsol 1) Vendor Id: 0x10ec0287 Subsystem Id: 0x17aa38b6 Revision Id: 0x100002 As far as I understand, this only works for the Realtek device. What you are looking for is the "Subsystem Id: 0x17aa38b6" or the second part of it "38b6". 2. DSDT table Confirm the I2C address (?) with the above mentioned lookup. My results: Method (_SUB, 0, NotSerialized) // _SUB: Subsystem ID { If ((RTSV == One)) { Return ("17AA38B7") } Return ("17AA38B6") } One matches the one from alsa info. To be sure I compiled two kernels. Spoiler alert, the one from alsa-info worked. 3. Edit Cameron's patch to the values you just found out. Since I'm running a newer kernel, the patch command did not work and I did it manually. Find the places in your kernels source /sound/pci/hda/cs35l41_hda.c file and copy the code from the patch. In your kernels /sound/pci/hda/patch_realtek.c file add one line in the code block where the patch added the code: "SND_PCI_QUIRK(0x17aa, 0x38b6, "Legion Slim 7 16APH8", ALC287_FIXUP_CS35L41_I2C_2)," Exchange "0x38b6" with your id from alsa info. I've also experienced, that it doesn't work if your device description ("Legion Slim 7 16APH8") is different from the one in your alsa info 4.Compile your own kernel. I followed https://wiki.archlinux.org/title/Kernel/Traditional_compilation That were the basic steps I took to make my speakers work. Please correct me if wrote something wrong, built my first kernel a few days ago... Thank you Cameron for putting in the time, I'd like to buy you some beer/coffee or send you flowers. I'm not kidding, write if you are interested... Created attachment 305210 [details]

Hi Cameron, Thanks for your patch for Legion S7 16IAH7. I try to applied this patch (and edit with subsystem id in alsa-info) for Legion Y9000X 16IAH7, but the speakers and jacks remain silent and I got some bad messages in dmesg(https://bugzilla.kernel.org/attachment.cgi?id=305210): [ 9.881918] genirq: Flags mismatch irq 58. 00002088 (cs35l41 IRQ1 Controller) vs. 00002088 (cs35l41 IRQ1 Controller) [ 9.881930] cs35l41-hda i2c-CSC3551:00-cs35l41-hda.1: Failed to request IRQ 58 for cs35l41 IRQ1 Controller: -16 alsa-info: http://alsa-project.org/db/?f=05d424dfcb9b901cfa001109e9edd97aa3904393 Probably won't work... IIRC, the smart amps aren't necessarily always on an i2c bus. It could be on the other bus (the name escapes me at the moment).

It doesn't have subwoofers. Perhaps you're right, and my laptop doesn't have subwoofers. However, when I listen to music on Windows 11, there's a significant difference in sound quality. On Windows, the sound is loud, expansive, deep, and rich in lower frequencies, among other qualities. In contrast, on Arch with a patch applied, the sound quality is roughly 50% of what it is on Windows. This difference is quite noticeable to me. If the laptop indeed lacks subwoofers, as I initially thought, what could be the reason for this discrepancy?

I personally mainly noticed a difference in sound volume.

I'm on a Lenovo S7 16IAH7 running on Debian 6.1.67. I installed the patch you had provided but my speakers still doesn't seem to work. I also tried following the suggestion made in comment 130, but to no avail. Could it be related to the kernel that I'm on? You can find my alsa-info and my dmesg. Hope the information provided was helpful! (In reply to Farrel from comment #140) > Created attachment 305669 [details] > alsa and dmesg > > > Hi Cameron, > > Thank you for your work with the patch.

Hope the information provided was helpful! Reading through all the comments on this issue, it seems the 16IAH7 just doesn't work. Maybe it's not even using i2c? Created attachment 305841 [details]

legion_7i-gen7_16IAX7-sound-6.7.3.patch
From newest kernel version it is possible to add legion quirk in easy way. I've tested it on kernel 6.7.3 and it works for my Legion 7i 16IAX7
I can't get sound from my Legion S7 16IAH7. I bought my device 2 years ago and I could never get the sound to work. I finally found this place, please help me. asla-info: https://privatebin.net/?71c5dc1d4e857a3a#42XU3YaPfT7zAm2Y2Q8mYU6H7uH5YGUJN8xRjX9Vy7zU (In reply to ramzes005 from comment #143) > Comment on attachment 305841 [details] > legion_7i-gen7_16IAX7-sound-6.7.3.patch > > From newest kernel version it is possible to add legion quirk in easy way. > I've tested it on kernel 6.7.3 and it works for my Legion 7i 16IAX7 I added a quirk for the Legion S7 16IAH7 following this format; it doesn't work, and have no idea why; if anyone is up for debugging this I'm happy to work with them. As a point of reference, I added the quirk to 6.8-rc5 on Opensuse Tumbleweed.

I just replaced the value 17AA386F with 17AA3878 and 0x386f with 0x3878 to match what I got from alsa-info.sh. Now sound seems to work well. Can this be merged into the kernel ? What are the risks ? Hi I recently buy this PC : https://www.asus.com/fr/displays-desktops/all-in-one-pcs/everyday-use/asus-aio-a5-a5402/techspec/ And i'm not able to have sound from speakers with Fedora 40.

Seems to be the same problem that you help to resolve for the Asus laptops. Just for you to know, I'm not a pro... Could you help me please?

That's assuming you wanted to go through the time & effort of figuring out how to build your own kernel. This error occurs because the BIOS doesn't have the values built-in that Linux needs to configure the amplifier chips. You could try asking Asus to add the values in. If enough people request this for this computer, Asus *might* do it. My understanding is that Asus had BIOS updates on a few of their gaming laptops a ways back to add the values in to get sound working under Linux. This isn't a portable computer like a laptop... I would personally just get external speakers for it. Very probably you could just plug speakers into the 3.5 mm jack. It probably wouldn't be that expensive to buy such speakers that sound as good or better than what's built in. It says the speakers are just 3w so they're probably not that great to begin with is my guess. If the 3.5 mm jack didn't work for some reason, there are probably USB devices you could plugin that Linux supports that would give you a speaker jack of some kind.

I dont' have the knowledge to build a kernel for fedora... that's too bad... I already wrote Asus about that, without any hope to have a positive answer. I will probably get external speakers as you suggested, waiting for any news in the future.

Turns out I'm wrong! My information is very out of date. By complete chance I was received an email notification a little while ago for a thread that I follow: https://kernel.ubuntu.com/mainline/ Looking into it... There's a generic fallback for Linux machines with Linux laptops. A quirk needs to be added for your machine and likely you'll get sound. Like this one: https://patchwork.kernel.org/project/alsa-devel/patch/20240213115614.10420-1-ramzes005@gmail.com/#25710895 I don't have a lot more time today to really post more about this... But I think we can test if the quirk works using intel-hda early patching to test it without compiling your kernel! See here: https://www.kernel.org/doc/html/v4.13/sound/hd-audio/notes.html#early-patching BUT you still need a recent kernel. If you're running Ubuntu, you can try: https://kernel.ubuntu.com/mainline/v6.8.8/ Ubuntu 24.04 has a 6.8 kernel, but it seems it doesn't have the support yet, but 6.8.8 from the mainline PPA does. You want to create an early patch that goes in /lib/firmware. I haven't done this in quite a while, so you'll have to go through this document. You'll need create a text file under /lib/firmware to set the [codec] field like this: [codec] 0x10de009d 0x17aa3f95 0 The first 2 fields are the vendor ID and subsystem ID of a laptop that's using the quirk you need. The last field needs to be the address which you can get from running "alsa-info". Search for "address: ". There might be more than one sound codec in your machine and it will only work with the address so keep that in mind. It's probably 0, but may not be. I could also have some details slightly wrong, it's been over a year since I've mucked with this. As the document probably already explains.. You'll need to reboot each time you change the file. Check for changes in dmesg that could give hints if you're making progress but I think it will either just work or not. Thank you... at least one way out of the impasse. On the other hand, the handling seems very complicated to me given my knowledge. I need to start by installing the latest kernel for Fedora (either 6.8 or 6.9) and what should I do next? After installing the package (I would would install the image package and the headers package), reboot to the new kernel... Then start reading the document I linked about early patching. What we're trying to do is tell the intel-hda driver that you have a different codec than what you actually have. This will work because the audio codec whose subsystem and vendor id's gave are compatible with your computer's and this will cause the "quirk" to be applied. The issue with the quirk is that these are generic values so the sound probably won't be as good as with Windows due to the lack of tuning for your specific hardware. Actually, now that I think about it... Share the link to your alsa-info so I can confirm if your sound hardware is compatible with that specific. I'm used to helping people with Lenovo laptops, not Asus iMac-esque desktop computers. :) On 4/28/24 12:55, bugzilla-daemon@kernel.org wrote: > https://bugzilla.kernel.org/show_bug.cgi?id=216194 > > --- Comment #151 from copernic75 (amartel@free.fr) --- > Thank you... at least one way out of the impasse. > On the other hand, the handling seems very complicated to me given my > knowledge. > I need to start by installing the latest kernel for Fedora (either 6.8 or > 6.9) > and what should I do next? > Is this ok?

I think the 0 address is likely accurate. do I have to give the file a specific name and extension? And do I add this line "CONFIG_SND_HDA_PATCH_LOADER=y" to the kernel parameter? Thanks for your time.. Created attachment 306232 [details] attachment-16182-0.html I don't recall if a special name is needed. That should be covered in the doc I linked. CONFIG_SND_HDA_PATCH_LOADER is a compile time option. It should already be built into your kernel so you shouldn't need it.

Thus, a patch file has to be located on the appropriate firmware path, typically, /lib/firmware. For example, when you pass the option patch=hda-init.fw, the file /lib/firmware/hda-init.fw must be present. https://www.kernel.org/doc/html/v4.13/sound/hd-audio/notes.html#early-patching The file only contains the line you told me : [codec] 0x10de009d 0x17aa3f95 0 And My kernel is : 6.8.8-350.vanilla.fc40.x86_64 I sure did something wrong... Thanks Share your dmesg output. That could give clues as to what's wrong. You might also try asking for help again on the Fedora forums. It's possible some of the instructions I've given you are wrong as I haven't done this very much and the last time was over a year ago. But we want to do is tell the Intel HDA driver that you have this other sound hardware so it applies the quirk for your machine, which will probably get your sound to work.

Skimming through the docs: https://www.kernel.org/doc/html/v6.8/sound/hd-audio/notes.html#early-patching This part of the doc seems to indicate that: The hd-audio driver reads the file via request_firmware(). Thus, a patch file has to be located on the appropriate firmware path, typically, /lib/firmware. For example, when you pass the option patch=hda-init.fw, the file /lib/firmware/hda-init.fw must be present. The patch module option is specific to each card instance, and you need to give one file name for each instance, separated by commas. For example, if you have two cards, one for an on-board analog and one for an HDMI video board, you may pass patch option like below: options snd-hda-intel patch=on-board-patch,hdmi-patch Looking into this more, I think your patch file needs to look more like: [codec] 0x10ec0294 0x10432084 0 [vendor_id] 0x10de009d [subsystem_id] 0x17aa3f95 I re write the patch /lib/firmware/hda-init.fw with your new indications... no sound also I followed this : https://community.frame.work/t/some-notes-on-audio-in-linux/8815 and created a file /etc/modprobe.d/hda-init.conf ... nothing and I have this : [ 11.203875] snd_hda_intel 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040380 [ 11.203914] snd_hda_intel 0000:00:1f.3: enabling device (0000 -> 0002) [ 11.204071] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 11.204185] snd_hda_intel 0000:00:1f.3: Applying patch firmware 'hda-init.fw' [ 11.204255] snd_hda_intel 0000:00:1f.3: Direct firmware load for hda-init.fw failed with error -2 [ 11.204258] snd_hda_intel 0000:00:1f.3: Cannot load firmware, continue without patching [ 11.264898] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC294: line_outs=1 (0x17/0x0/0x0/0x0/0x0) type:speaker [ 11.264904] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 11.264907] snd_hda_codec_realtek hdaudioC0D0: hp_outs=1 (0x21/0x0/0x0/0x0/0x0) [ 11.264909] snd_hda_codec_realtek hdaudioC0D0: mono: mono_out=0x0 [ 11.264910] snd_hda_codec_realtek hdaudioC0D0: inputs: [ 11.264912] snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19 [ 11.264913] snd_hda_codec_realtek hdaudioC0D0: Internal Mic=0x12 at least the patch is trying to be loaded at boot time with the first patch

Hi everyone, I've encountered an issue with my ThinkBook 16p Gen5. Only the top two speakers have sound, and it's very quiet. I tried using the following patch to fix the problem, and while the error messages in dmesg are gone, the issue remains unresolved. Here's my alsa-info: http://alsa-project.org/db/?f=7c6523edf0911cfdbdb60642fce81e350c9b350b And here's my kernel information: 6.8.8-zen1-1-zen Hi @Yage, have you found a solution? I face the same problem in my ThinkBook 16p Gen5. Ubuntu 24.04. Sound is terrible.. @Cameron did you ever setup a git for this, I saw it mentioned but I haven't seen any other reference to it. I find it amazing that you have helped so much. The community should buy you many many favorite beverages. I'm running a Lenovo Slim 7i 16IRH8 with the Cirrus Logic Amp CSC3551 and the Realtek alc3306. I do have sound but it is terrible and I see the Realtek ALC3306 has been identified as a ALC287 and my CSC3551 is borking out and identified as a cs35l41. I have tons of messages that state it cannot load the firmware, falling back to default, unable to find firmware tuning, etc etc. My sound is 50% that of Windows and I have EasyEffect'd the heck out of this thing. No matter what I try, it just cannot compared. Had I known I would switch linux, I wouldn't have bought this thing a year or so ago. At this particular point, I'm curious if this is being addressed and an eventual patch will be applied to the kernel? Is this custom patch something that might help me? @Dimitris, I am with you...same thing here. Sound is terrible. Thank you. ALC287 and ALC3306 are the same thing. The CSC3551 is supported by the cs35l41 driver. What's almost certainly happening is that your laptop has no tuning info in the DSDT and there's no firmware... So the driver is using safe defaults that won't damage your speakers which is why the volume isn't great. While it's certainly better than nothing, it's not a great experience. This is because Lenovo does not and will not support these laptops as far as Linux goes. Hopefully, Lenovo will start supporting Linux on their gaming laptops in the future... Semi on/off topic: For now, I'm happy with my Legion 7i Gen 8, and when the time comes to upgrade, I'll go with a gaming laptop that provides a better experience (Asus is potentially better here). The Legion 7i Gen 8 actually has firmware... But the BIOS situation isn't great. Legion team released a beta BIOS that fixed the constant ACPI errors filling up your disk space... But they have no interest in putting those changes into their mainstream BIOS releases and there have been several regular BIOS releases since then and who knows how many security fixes. One might be able to dump the DSDT from the beta BIOS and use it to do a DSDT override with a newer release... But I just haven't had the time to try it myself and will not for the foreseeable future. So yeah, the situation isn't great even with my machine... But at least it sounds pretty good with official firmware released for the smart amps.

I thank you for the response and hope for a nice beta bios or something that will help this sound issue in the future. When I update this machine, I will look toward more open support for the hardware. I really never expected to be running Linux on the desktop so much but the alternatives are ultimately just pushing me away. I just want to say, your help in this thread has been incredible. I know many appreciate it.

I'm going to wait for other Linux users to report back. :D Hopefully Lenovo eventually figures out that people want to run Linux on gaming laptops too! Thanks to Proton, gaming on Linux is shockingly good these days. I'm in Linux 95% of the time on my current Legion (and 99% on my desktop), because most games I care about run great under Linux (and because I don't have a ton of time for gaming on ANY platform these days).
