Description Andreas Kloeckner 2019-10-17 18:34:17 UTC
I have brand-new Dell XPS 13 7390 2-in-1, based on Intel's 10th-generation hardware. I built kernel 5.4rc3 following instructions here [1]. After I put the machine to sleep (s2idle, not ACPI S3), and wake it up, any attempt to access /dev/snd/pcmC0D3p will hard-hang the associated process. In addition, any attempt to play sound after that point (on the built-in or the HDMI codecs) will hang for a while and then time out. Here's the strace of a process trying to access /dev/snd/pcmC0D3p:

ioctl(11, SNDRV_CTL_IOCTL_PVERSION, 0x7ffe01520b84) = 0
ioctl(11, SNDRV_CTL_IOCTL_PCM_PREFER_SUBDEVICE, 0x7ffe01520bec) = 0
openat(AT_FDCWD, "/dev/snd/pcmC0D3p", O_RDWR|O_NONBLOCK|O_CLOEXEC

After that, it just sits there and cannot be killed. /dev/snd/pcmC0D3p is an HDMI audio output as far as I can tell. I have an external screen with audio output attached most of the time, but the issue occurs even without any such hardware attached. In the "hang" situation, the following is shown in the kernel log:

Comment 1 Andreas Kloeckner 2019-10-21 02:41:48 UTC
I was using some script to unbind the Thunderbolt controllers from their hardware on suspend, which appears to have indirectly confused the audio drivers.

IOW, nothing to see here as far as I can tell. Sorry for the noise!

Comment 2 Andreas Kloeckner 2019-10-31 21:01:17 UTC
A BIOS upgrade and the removal of the Thunderbolt suspend fix have lessened the incidence of this issue, but the program hangs in conjunction with

[ 1673.440034] snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: last cmd=0x202f8100
[ 1674.448043] snd_hda_intel 0000:00:1f.3: No response from codec, disabling MSI: last cmd=0x202f8100
[ 1675.456078] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x202f8100
[ 1676.468278] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x202f8100

in dmesg do still occur, often in conjunction with plugging in and/or removing external monitors from the Thunderbolt ports of the machine.

I'd be grateful for any advice in tracking down what the problem might be. In particular, I'm happy to run patched kernels if that helps.

Thanks in advance!

I have the same issue.

Call traces during suspend

I've attached call traces from dmesg during suspend which causes suspend exit.
Comment 5 Takashi Iwai 2019-11-02 10:08:43 UTC
There is a known mutex deadlock up to 5.4-rc5.  The fix is already in Linus tree and will be in rc6.

This won't fix the codec communication error the original reports suggests, but the hang up can be addressed by that.

And the codec communication error is likely caused by other component like GPU or Thunderbolt side, not in the audio side.  It's a pseudo device on GPU, after all.
Comment 6 Arek Burdach 2019-11-02 10:18:18 UTC
After attaching this stack trace, I've found out that there is a fix for this. I'll check in a moment if it will fix suspend issue.

Regards to communication error, will try to do some more investigation. Thanks for notice.
Comment 7 Andreas Kloeckner 2019-11-04 23:23:15 UTC
> This won't fix the codec communication error the original reports suggests,
> but the hang up can be addressed by that.

I'm on 5.4-rc6 now, and I still have the issue as originally described. I wasn't able to observe any change in behavior from 5.4-rc5 to 5.4-rc6.

Comment 9 Andreas Kloeckner 2019-11-04 23:50:24 UTC
A few more details:

- There is a Debian code signing issue flying around, where the issue appears to be related to not being able to even load snd-hda-intel. (IMO) that's distinct from the current issue.

- For me, a semi-reliable way of triggering the issue is to plug in and un-plug an external monitor (DisplayPort) monitor into either USB-C jack on the machine that advertises HDMI audio support.

- I suspect that "options snd_hda_intel probe_mask=1" will prevent snd-hda-intel from enumerating the HDMI codec and thus perhaps sidestep the issue for now. No HDMI audio is more livable for me than random hangs and suspend failures...

Comment 10 Kai Vehmanen 2019-11-07 15:58:07 UTC
I made a few patches to i915 driver that are worth trying. They don't seem to be in v5.4-rc6 yet.

Comment 11 Andreas Kloeckner 2019-11-07 19:45:59 UTC
I built a kernel based on drm-tip (41eb27f39e60d822edc75e6aaeb416b72bc1dcf2), which appears to contain the patches in question. In a quick experiment (plugging in and unplugging a bunch of displays), I wasn't able to reproduce the issue. Let's call this fixed, and I'll reopen in case the issue recurs.

Thanks for your work on the patch, and for pointing me towards it!
Comment 12 Kai Vehmanen 2019-11-08 14:14:26 UTC
Excellent, thanks Andreas for testing! The patch is indeed already merged to drm tree.

Shouldn't this issue been fixed ? 

I can't use HDMI audio at all, only way to avoid error is: options snd_hda_intel probe_mask=1 , but I would need to use my HDMI audio ...

This has J4105 (Geminilake) CPU, so it is slightly different hardware generation than the original bug report (Icelake), so this may be a different issue although the messages are similar. 

You could try this patch that was recently merged to DRM-Intel tree:
"drm/i915: do AUD_FREQ_CNTRL state save on all gen9+ platforms"

Depending on system firmware settings, this may have an impact to enabling the HDA link between graphics and audio controller on your system.

I just very recently got the patch through reviews, so it is not yet in 5.7rc2 even.
Comment 15 Nathan Bryant 2020-05-01 20:42:02 UTC
I have an Ice Lake laptop (Dell 7390 2-in-one) which I am connecting to a TV over HDMI via a Novoo USB-C multiport adapter. This is not a Thunderbolt device, it is just USB-C.

It seemed like things used to work fine before I upgraded this system from Ubuntu 19.10 to 20.04, although I couldn't say for certain at this point. But I'm having a ton of difficulty getting audio output over HDMI. Getting it to work requires a lot of random plugging and unplugging of cables, and repeatedly messing around in the system settings to change output devices and volume levels. It does work sometimes, but my success rate is very low at this point.

For example, just now as I wrote this, I was briefly successful, but then I changed the output setting from 7.1 channel to 5.1, and it stopped again (without plugging or unplugging any cables or changing any video settings in the interim.)

The patch posted above by Kai Vehmanen is not relevant because this system is Ice Lake and the patch only enables logic for non-ICL, post gen9 platforms.
Comment 16 Greg Meyer 2020-05-18 17:55:28 UTC
I'm also still seeing the same behavior (at least, it seems like the same behavior), on Dell 7390 2-in-1 running Manjaro.

$ uname -r
5.6.11-1-MANJARO

I have the issue of applications hanging in an unkillable state maybe 1 in 5 boots, making me force a shutdown and reboot until it works. (This is even without connecting any external displays etc!). Also, I don't have any HDMI audio out ever.
Comment 17 Nathan Bryant 2020-05-18 19:08:27 UTC
Greg, that's interesting. I do get HDMI audio if I fiddle enough (repeatedly suspending and resuming helps to eventually force it to initialize properly), it's just that there are intermittent problems with it. Sometimes I've found that the volume needs to be reset after changing output configuration, but that's not usually the problem.

Are you using the *XPS* 7390 2-in-1 or the *Latitude* 7390 2-in-1? Mine is the XPS.
Comment 18 Greg Meyer 2020-05-18 19:55:54 UTC
Huh. I also have the XPS. By the way, I just checked and I'm running BIOS revision 1.3.1 (which is up-to-date according to the windows updater, at least).

I have tried a few times to fiddle, suspend and wake again, etc. to try to get things working, but never had any luck. Maybe I just didn't try hard enough!

I also have an issue when I do have an external display connected where often times after suspend the external display doesn't come back when I resume. not sure if it's related though.
Comment 19 Nathan Bryant 2020-05-18 21:49:08 UTC
Filed my issue at https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1879401
Comment 20 Mateusz Tracz 2020-06-24 12:23:15 UTC
I am suffering from exactly the same issue. 
It happens once every couple of boots and also after waking up from suspend, possibly also after waking up from hibernation to disk.

It's XPS 9300 laptop with i7-1065g7 CPU.

There is a partial workaround that I am using: 


# echo 1 > '/sys/bus/pci/devices/0000:00:1f.3/remove'
# sleep 1
# echo 1 > /sys/bus/pci/rescan

Sometimes I need to do it once, sometimes even 3 or more times. 

After that reloading pulseaudio is also needed 

$ pulseaudio -k

Most of the time I don't see this, but I may have other audio problems (silent output noted above).

The only time I really noticed a problem and saw this message was the day before yesterday. When this happens, the whole system seems to slow down and wait for these retries, so I rebooted to fix it. I have been running various kernel versions, ranging from Ubuntu's 5.3, 5.4 and 5.6-oem trees to mainline 5.6. I'm not running mainline anymore because Ubuntu's tree is working better in general these days, so most recently I am on Ubuntu 5.4 as 5.6 is EOL upstream.
Comment 22 Kai Vehmanen 2020-06-24 14:27:59 UTC
Nathan, Mateusz, Greg and others, if possible, you could give a try for this patch (in 5.8-rc2):

commit 1c664c15cf0a31784b217a84fa0128ce46f17a84
Author: Kai Vehmanen <kai.vehmanen@linux.intel.com>
Date:   Tue Mar 24 17:32:12 2020 +0200

    drm/i915: use forced codec wake on all gen9+ platforms


.. we are not seeing this error in SOF audio and Intel GFX CI systems. These both have had the above patch for many months, so that could possible explain. The above patch specifically affects platforms with gen10 display, so Icelake and Geminilake, so matches with the observations in this bug.
Comment 23 Takashi Iwai 2020-06-24 14:55:46 UTC
Kai, could you submit the commit to stable kernels?  Just tell Greg the commit id to cherry-pick.
Comment 24 Kai Vehmanen 2020-06-24 18:34:00 UTC
Takashi, ack, I'll do that. I'm a bit surprised this didn't get cc'ed to stable by DRM maintainers (it was merged to DRM ages ago), nor picked up by Sasha's stable scripts. For sound subsystem patches, all of my patches with a bug link have been automatically picked up.
Comment 25 Nathan Bryant 2020-06-24 19:52:12 UTC
All right, I'll track 5.8-rcX for a while and see where we end up.
Comment 26 Nathan Bryant 2020-06-24 20:10:29 UTC
OK, right out of the gate with 5.8-rc2, there are still some negotiation issues with my Type-C multiport adapter, including the silent audio output I referenced in Comments 15 and 19, and, a lot of these, requiring a couple of hotplug retries to get them to go away:

[Jun24 16:05] usb usb2-port3: Cannot enable. Maybe the USB cable is bad?

So far, no recurrence of the "No response from codec" issue, but I've only been testing for about 5 minutes and this issue happens just a handful of times per month.
Comment 27 Nathan Bryant 2020-06-29 02:11:21 UTC
Still seeing this on 5.8-rc2:

I don't know if this is relevant, but the above was preceded by this:

Comment 28 Kai Vehmanen 2020-07-02 10:32:33 UTC
Thanks Nathan for testing! This indeed looks like a new case. Could you try the following experiment(this will increase power consumption, so to try rootcausing the issue). Put following in a .conf file in /etc/modprobe.d/ 

i915.disable_power_well=0 

If that doesn't help, next step would be to revert this patch from 5.8-rc2:

commit f4b18892dca8 drm/i915: Limit audio CDCLK>=2*BCLK constraint back to GLK only

Jaroslav, should we reopen or file a new ticket for this? There was one bug that was fixed and verified (in Nov/2019), but now we have a new issue. Problem looks to the same, communication fails with display hw and audio probe fails.
Comment 29 Nathan Bryant 2020-07-03 14:40:30 UTC
Hi Kai,

I added i915.disable_power_well=0 to the kernel commandline in /etc/default/grub and rebooted into 5.8-rc2. I have graphical boot disabled and noticed this scroll by immediately on boot (HDMI was already plugged in)

Comment 30 Nathan Bryant 2020-07-03 14:46:07 UTC
For completeness I'll note my full cmdline:

$ cat /proc/cmdline 
BOOT_IMAGE=/boot/vmlinuz-5.8.0-050800-generic root=UUID=caffa21a-82f2-4555-a416-67926241525a ro cma=128M pcie_aspm.policy=powersupersave drm.vblankoffdelay=1 video=1600x1200 mem_sleep_default=deep i915.disable_power_well=0

Speaking of power management: in the past, I've indeed noticed that ASPM seems related to some of these Type-C issues; sometimes, on some kernel versions, it's seemed that setting the ASPM policy to "performance" helps reduce the frequency of (but not entirely eliminate) silent output issues. (Also prevents the package from going deeper than C3 state according to powertop.)
Comment 31 Nathan Bryant 2020-07-03 19:08:23 UTC
I've built a kernel with f4b18892dca8 reverted.

So far so good on the "No response from codec" message. Still some intermittent issues with silent audio. Will run this for a few weeks and see if "No response from codec" comes back.
Comment 32 Nathan Bryant 2020-07-07 12:45:48 UTC
I'm still testing with f4b18892dca8 reverted, now based on 5.8-rc4. Something new happened. I saw the message "usb usb2-port3: Cannot enable. Maybe the USB cable is bad?" while booting (it was still on the console, but just moments away from initialiaing X), so I unplugged and replugged the USB-C multiport hub that I use for HDMI connectivity. (If I don't do that, I tend to get spammed with these messages for hours.)

Comment 33 ItsMe 2020-07-08 01:21:19 UTC
For me, adding 'options snd_hda_intel power_save=0
' in '/etc/modprobe.d/audio_powersave.conf' fixed this issue.
Comment 34 Nathan Bryant 2020-07-12 15:09:32 UTC
Hi Kai,

It appears that the issue still occurs even with f4b18892dca8 reverted:

Moreover (as I suspect you are already aware), reverting f4b18892dca8 causes bad flicker when not on HDMI, any time snd_hda_intel wakes up from sleep.
Comment 35 Kai Vehmanen 2020-07-15 13:54:48 UTC
Thanks Nathan. There are now two possible sources of the problem:
 1. clocking issue when display clock (CDCLK) goes to its lowest setting
 2. hda controller issues when resuming from suspend

Reverting f4b18892dca8 indeed causes flicker as the CDCLK is ramped up higher whenever audio is used. I asked for the test, because if the errors would have disappeared, then a possible usable fix would be to bump the minimum CDCLK (in i915 driver) for your configuration. But it didn't help, so it is likely not this.

For the second issue type, it's unclear to me now why this impacts specifically the HDMI codec (and the Realtek codec probe does not fail). But it's definitely interesting that both "ItsMe" above, and reporter of https://bugzilla.kernel.org/show_bug.cgi?id=208511 , have given feedback that snd_hda_intel power_save=0 helps for a HDMI probe error (not exactly the same hw, but GLK and ICL are close enough to make this worth cross-checking). Does this help Nathan for you?

I'll keep looking for an occurrence of this case in our internal test benches.
Comment 36 Nathan Bryant 2020-07-15 17:40:06 UTC
This kernel message appears to manifest in two different ways:

(1) just the two messages, just one time, and then it stops, and I'm unclear whether it's connected to a user-visible functional issue.
(2) repeatedly in a loop, causing quite a bit of log spam and user-visible system sluggishness.

Case (1) happens with some regularity with many different kernel versions but I'm not sure if there's a real problem beyond the kernel message. I usually just find these after-the-fact, in the system logs.

Case (2) has happened to me a few times, but from my logs, the most recent times were Jun 22 (version_signature Ubuntu 5.4.0-38.42-generic 5.4.44) and Jun 24 (Ubuntu 5.6.0-1013.13-oem 5.6.14)

So there might be a couple slightly different issues, one of which has not recurred recently and in either case I couldn't even say with certainty that this is coming from the HDMI codec. The kernel logs don't look that specific to my eyes. So this may not be the highest-priority bug in the world, either, but  I will try with power_save=0 for a while and see what happens.
Comment 37 Nathan Bryant 2020-07-16 15:28:58 UTC
I guess it *is* HDMI. I'm also seeing this mixed in:

Unfortunately I am still seeing the same issue with this option set. :/
Comment 39 LordKow 2020-08-25 16:37:53 UTC
Confirmed this bug is still prevalent:
.4.0-42-generic #46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux


Only solution I have found is to repeatedly hard power-off the laptop and turn it back on continuously until the error no longer appears. Unfortunately this corrupted the linux install for obvious reasons so I had to completely wipe the drive and revert to Windows. I have 0 interest in reinstalling Linux, just thought I would post this to inform the kernel team there are still major issues with the snd_hda_intel. Either fix it or drop Intel sound support. Buggy code like this should not be in the kernel tree.
