Description jkp 2013-06-16 17:56:25 UTC
The Asus transformer book tablet/notebook hybrid has two sets of speakers, in the tablet part and in the dock (with keyboard and HDD) part. The tablet speakers work fine, but no sound is output from dock speakers, and no option shows up in ALSA to select dock output. I wonder if some kind of quirk is required for dock sound to be enabled.

Comment 1 jkp 2013-06-16 21:16:36 UTC
I found the PIN to switch the dock speakers on - with HDAAnalyzer, it's node 0x1b, from the GUI it's "Widget Control" "Out", or as a number 0x40 in text-mode at Pin-ctls.
Comment 2 jkp 2013-06-16 21:19:45 UTC
With hda-verb dock speaker can be switched on with:

# ./hda-verb /dev/snd/hwC0D0 0x01b SET_PIN_WIDGET_CONTROL 0x40

and off with:

# ./hda-verb /dev/snd/hwC0D0 0x01b SET_PIN_WIDGET_CONTROL 0x20

(not sure of the 0x20 (IN) bit meaning though)
Comment 3 jkp 2013-06-16 21:45:57 UTC
Also GPIO 2 of codec-0 needs to be switched on for dock sound to work.
Comment 4 jkp 2013-06-16 22:00:31 UTC
.. And 0x1b needs also to be unmuted.
Comment 5 jkp 2013-06-16 22:35:47 UTC
Ideally this should work so that dock (has keyboard & displayport) speakers (which are better) will be automatically used when the tablet part is docked to the keyboard, and again when the tablet part is undocked, the table speakers would be used. Not sure of how to sense dock/undock.
Comment 6 Takashi Iwai 2013-06-17 09:24:32 UTC
When the pin 0x1b is changed and GPIO2 is set, does the sound come from both dock and tablet, or only from the dock?  In non-ideal but a feasible fix is to just enable this pin and GPIO constantly.

Possibly the codec reports the dock connection state via some jack-detection bit.
Try to run hda-verb like
    hda-verb /dev/snd/hwC0D0 0x1b SET_PIN_SENSE 0
    hda-verb /dev/snd/hwC0D0 0x1b GET_PIN_SENSE 0

and see whether the latter command shows the bit 31 on/off per dock/undock.
If 0x1b doesn't show the difference, try other NIDs for pin widgets with the detection capability, e.g. 0x18, 0x19, ... (look for "pincap" with "detect" in the codec proc output).
Comment 7 jkp 2013-06-17 09:41:48 UTC
It comes from both dock and tablet.

One way to silence tablet output I found is to tune output amp dials to 0 in node 0x02 - sound still comes from dock when I do that.

I'll test the detection when I can undock from the HD, that's in use now.
Comment 8 jkp 2013-06-17 09:42:49 UTC
Turning GPIO 0 & 1 off doesn't silence the tablet output.
Comment 9 jkp 2013-06-17 09:47:45 UTC
Node 0x14 mute boxes also mute the tablet speakers while letting sound hear from the dock.
Comment 10 jkp 2013-06-17 09:54:21 UTC
You're correct, GET_PIN_SENSE 0 at node 0x1b can be used to sense dock state - output from looping with the command, first docked, then undocked, then docked again.

hda-verb /dev/snd/hwC0D0 0x1b GET_PIN_SENSE 0

nid = 0x1b, verb = 0xf09, param = 0x0
value = 0x80000000
nid = 0x1b, verb = 0xf09, param = 0x0
value = 0x80000000
nid = 0x1b, verb = 0xf09, param = 0x0
value = 0x80000000
nid = 0x1b, verb = 0xf09, param = 0x0
value = 0x0
nid = 0x1b, verb = 0xf09, param = 0x0
value = 0x0
nid = 0x1b, verb = 0xf09, param = 0x0

nid = 0x1b, verb = 0xf09, param = 0x0

Fix patch for ASUS TX300 dock pin and GPIO
Comment 15 jkp 2013-06-17 12:38:54 UTC
One issue with the sound is the external combo jack connector. From a bit of googling, seems like this is either headphone or mic, switchable by software. It works fine as headphone output, but I haven't found a way to use it as mic input with Linux. With node 0x11 mute I can mute the internal microphone(s?), but I can't find how to enable a jack-connected microphone.
Comment 16 Takashi Iwai 2013-06-17 14:29:56 UTC
3.10 kernel has a few headset support for ALC269 & co, and this might work for this device, too.  Also, for a TRRS type headset, the fix for ASUS X101CH might be usable for this device, too.  For more complicated headset support, the code we took for Dell machines might help, too.

But, in anyway, we need to go step by step.  Did the patch work for the dock output, at least?
Comment 17 jkp 2013-06-17 14:47:47 UTC
Ah, I didn't notice the patch before writing the jack message - I'll test.
Comment 18 jkp 2013-06-17 15:04:45 UTC
Yes, the patch works with 3.10-rc6. Sound comes from both the dock speakers and the tablet speakers.
Comment 19 Takashi Iwai 2013-06-17 15:31:24 UTC
OK, and are the tablet / dock speakers switched automatically?  Or do both of them sound at the same time if it's docked?
Comment 20 jkp 2013-06-17 15:45:16 UTC
Thanks for the patch and tips wrt headset mic - tested this:

	SND_PCI_QUIRK(0x1043, 0x103f, "ASUS TX300", ALC269_FIXUP_ASUS_X101),

but no input from a mic/headset combo. But my understanding is that the computer has a combo jack which means it takes either headphones or mic but not both at the same time.
Comment 21 jkp 2013-06-17 15:45:45 UTC
From both at the same time when docked.

Give alsa-info.sh outputs with this change while you're testing from the external mic.  Possibly something was forgotten in the setup.

Also,

(In reply to comment #21)
> From both at the same time when docked.

... give alsa-info.sh outputs before and after dock, too.

The patch assumes that the unsolicited event is generated at docking, which should change the pin NID 0x14 respectively.  If the event isn't generated, a polling would be another option.  For example, pass jackpoll_ms=100 option to snd-hda-intel module.
Comment 23 jkp 2013-06-17 16:28:19 UTC
The report about sound coming from both at the same time was when docked at the time the sound modules were loaded; I didn't test undock/dock but I will.
Comment 24 jkp 2013-06-17 17:29:03 UTC
Starting at docked state, going to undocked, then docking back - in all cases sound comes from tablet internal speakers.

Will attach alsa-info.sh output.

Comment 28 jkp 2013-06-17 17:49:16 UTC
Hmm - looking at the patch code, I don't see anything related to NID 0x14 which is the one to silence output in tablet - I wonder if I'm just overlooking it or if you accidentally posted a wrong version of the patch.
Comment 29 jkp 2013-06-17 18:18:32 UTC
Same results with jackpoll_ms=100 option, still sound at tablet side even when docked.
Comment 30 Takashi Iwai 2013-06-18 13:29:23 UTC
Hm, OK, then please try to take tracepoints for better analysis.

- Build your kernel with trace support
- After boot, you'll have /sys/kernel/debug/tracing/*
- Take alsa-info.sh snapshot at this moment
- Enable the tracing via
     echo 1 > /sys/kernel/debug/tracing/events/hda/enable
- Dock or undock
- Get the tracepoints via
     cat /sys/kernel/debug/tracing/trace > /tmp/trace.log
- Disable the tracing
     echo 0 > /sys/kernel/debug/tracing/events/hda/enable
- Take alsa-info.sh output again

Then attach the two alsa-info.sh outputs and the trace log.
Some more details are found in Documentation/sound/alsa/HD-Audio.txt.
Comment 31 jkp 2013-06-18 22:34:17 UTC

Comment 32 Takashi Iwai 2013-06-19 05:45:46 UTC
Try to do some more actions, e.g. playing a stream or changing the mixer value.
If there is still no trace, it means that the tracing support isn't built properly in your kernel.  Try to enable relevant kernel configs.

If any events are recorded by the explicit action but nothing from dock/undock, then it means that the codec doesn't get unsolicited events from the dock.
Comment 33 jkp 2013-06-19 07:47:02 UTC

Not /sys/.../hda_intel/enable but /sys/.../hda/enable.
Comment 36 jkp 2013-06-19 11:07:34 UTC
Yes, sorry, cut & pasted the wrong command. "echo 1 > /sys/kernel/debug/tracing/events/hda/enable" is what I did first - tried also hda_intel just in case which came up in the cut&paste, but no trace output with hda/enable or hda_intel/enable.
Comment 37 Takashi Iwai 2013-06-19 12:04:35 UTC
Hm, then I have no idea what prevents tracing.  Do other trace events work as expected with that kernel?

I'm not familiar with kernel tracing before, but I'd say yes, as after echo 1 >  /sys/kernel/debug/tracing/events/syscalls/sys_enter_umask/enable and trying the umask syscall I get this in trace:

Comment 39 Takashi Iwai 2013-06-19 15:23:32 UTC
Then try again whether any specific event comes up by each of /sys/kernel/debug/tracing/hda/*/enable.  It's weird because there is nothing special in the setup.
Other than that, what I can think of is only the filter.  In anyway, check the file contents of enable and filter in each directory after enabling (just do cat).
Comment 40 jkp 2013-06-19 16:02:59 UTC

Hm, then try to put some garbage like #error XXX in sound/pci/hda/hda_trace.h, and check whether the code is really compiled in.  Or check snd-hda-codec.ko via objdump and see whether it has some sections/definitions for ftrace.

Comment 46 Takashi Iwai 2013-06-20 11:02:45 UTC
Hm, then I have no idea why it doesn't work.

OK, let's forget about the tracepoints but try the traditional printk's.
Apply the patch below temporarily and see the kernel messages at docking/undocking.  Especially whether an unsol event on NID 0x1b is shown.

To check whether it really shows the unsol event, you can try to plug to the headphone jack.  This should issue the unsol event certainly.

Patch for automatic tablet mute/unmute & dock sound enable

This is a patch against 3.11.0. In addition to incorporating the earlier code, there's more debug and new code to mute tablet speakers when docking.

The patch is not clean yet, as it appears there's a previous callback which causes the callback not to work with normal hda_jack.c code; for testing, I kludged the code in hda_jack.c to replace the previous callback. Must be debugged what the previous callback is and properly fixed and debug output cleaned before considering for merging.
Comment 55 jkp 2013-09-04 18:09:15 UTC
Takashi, can you look at the patch in attachment 107402 [details], and perhaps see if you can shed some light into the callback issue mentioned above?

Other advise on how best to proceed in getting a fix merged?
Comment 56 Takashi Iwai 2013-09-05 12:28:54 UTC
You can register the callback at action==HDA_FIXUP_ACT_PRE_PROBE time so that it'll be registered before the generic parser does.

But, another problem in your patch is that you change the amp of NID 0x14 forcibly, and this conflicts with "Speaker Playback Switch" control.  That is, if you mute the output and dock, then the speaker is unmuted although the mixer still shows muted.

Below is a patch with a new approach.  It's for the current Linus tree, but can be applied to 3.11 easily, too.  3.10 might not work with the patch due to missing fixes for automute_via_amp flag.

Comment 58 jkp 2013-09-05 13:43:13 UTC
Thanks, applied with some manual help to 3.11, I'll test.
Comment 59 jkp 2013-09-05 14:28:25 UTC
Test results:

* Dock sound works when docked, tablet is silent
* At docking, there's a click (like with my patch) suggesting the speaker switching works
* No sound when undocked
* Then I start HDAAnalyzer, look at Node 0x14 PIN, notice the Mute boxes are checked
* After unchecking the boxes, sound works when undocked
* Reboot, then Mute boxes are again checked
* Try to see if alsamixer can be used to unmute - can't find any way to do it
* Take away the checks from Node 0x14 PIN Mute boxes, sound works again when undocked
* Dock again; unfortunately, now sound again is heard from both speaker sets (with Mute boxes not checked).
Comment 60 Takashi Iwai 2013-09-05 14:53:56 UTC
Check whether asus_tx300_automute() is called at each time you dock, undock or headphone plug/unplug.  After calling this, snd_ctl_sync_vmaster() will be called and this will update the mute states of 0x14 and 0x1b.

For invoking alsamixer, run with -c0 option.  The "Speaker" item should have the mute capability, toggled via 'M' button.
Comment 61 jkp 2013-09-05 16:41:40 UTC
asus_tx300_automute is not called at undock/dock. I added similar/same debug lines than in my patch, and one at start of asus_tx300_automute.

At startup:

[   10.954002] XXX tx300 automute called
[   10.954007] XXX tx300 automute jack_detect = true

Unsol event is received at undock:

Unsol event at dock:

No asus_tx300_automute at either dock or undock.
Comment 62 jkp 2013-09-05 17:01:47 UTC
I also added debug messages to snd_hda_gen_hp_automute() and no output from that, so that's not even called snd_hda_gen_hp_automute().
Comment 63 jkp 2013-09-05 17:03:28 UTC
Ah, it's probably the same issue as I had with the callback, there's a callback already registered:

[    6.703004] XXX snd_hda_jack_detect_enable_callback, jack=0x15f56c38 already registered
Comment 64 jkp 2013-09-05 17:15:23 UTC
By commenting out the "return 0" in snd_hda_jack_detect_enable_callback(), snd_hda_gen_hp_automute() is entered, but it exits before call_update_outputs(codec);
Comment 65 jkp 2013-09-05 17:17:46 UTC
Maybe add

		spec->gen.automute_speaker = 1;

or something like it in the tx300 automute setup?
Comment 66 jkp 2013-09-05 17:31:06 UTC
Adding 

		spec->gen.automute_speaker = 1;

didn't help, snd_hda_gen_hp_automute() still exits before call_update_outputs(codec);
Comment 67 jkp 2013-09-05 18:53:20 UTC
Tried also adding

 		spec->gen.detect_hp = 1;

- didn't help.

However, when I comment out the return at snd_hda_gen_hp_automute(), it works, and tx300 automute gets called.

In other words, your code with two additions, the return at snd_hda_gen_hp_automute() and the return snd_hda_jack_detect_enable_callback() comment out, your code works. These are obviously not the real fixes, but will perhaps help in finding what's wrong with the code.
Comment 68 Takashi Iwai 2013-09-06 07:46:06 UTC
I guess either the patch was applied wrongly or you changed "Auto-Mute Mode" mixer to off accidentally (and it's taken over via alsactl).  Try the patch below instead.  Apply it cleanly on the top of 3.11.

If it still doesn't work, show alsa-info.sh output.

Fix patch for 3.11
Comment 70 jkp 2013-09-06 08:08:30 UTC
Your're correct about Auto-Mute Mode being off - wasn't familiar with the setting. Will test your new patch.
Comment 71 jkp 2013-09-06 09:23:01 UTC
Test results:

* Auto-Mute Mode was off by default when the sound modules were unloaded/loaded; alsactl store after enabling Auto-Mute mode fix this. I haven't changed the state on purpose, so I've either changed (and stored? or is it auto-stored?) it accidentally or it's the OS default to have it off.
* With Auto-Mute Mode on, the auto-changing of nid 0x14 works as expected, in other words dock and only the dock speakers are on when docked, and tablet speakers work when not docked

So, basic things seem to be good and well, thanks.

About mixer settings - not sure how this is supposed to work, but from the names and your comments, I would expect "Speaker" to correspond to internal tablet speaker, and "Dock Speaker" to be the dock speaker, and thus would expect things to work like this:

* AlsaMixer (command line) "Speaker" mute would control the tablet internal speaker mute and be "M" (muted) when docked
* AlsaMixer "Dock Speaker" mute would control dock speaker mute and be "M" when undocked

Instead, this is how it behaves, in a way that's unexpected to me:

* When docked, "Speaker" is not muted (not marked with 'M's)
* When undocked, "Dock Speaker" is not muted
* When docked, muting either "Dock Speaker" or "Speaker" mutes the sound.
* Muting "Speaker" adds mutes also to "Master" and "Headphone"

This is as I expect it to be:

* When docked and after using HDAAnalyzer to remove NID 0x14 mutes so sound comes both from dock & tablet speakers, muting Dock Speaker mutes the dock speakers and lets the tablet speakers work
Comment 72 Takashi Iwai 2013-09-06 09:37:06 UTC
"Auto-Mute Mode" is on as default in the driver level.  It must be alsactl who changed it at module loading time (usually triggered by udev), which also saves the value at shutdown.  The system-default value is found usually in either /var/lib/alsa/asound.state or /etc/asound.state.

The "Speaker" and "Dock Speaker" mixer controls are independent from the dock/undock status.  The mute of the tablet speaker is done at docking no matter whether "Speaker" is muted or not, as long as "Auto-Mute Mode" is set.
Ditto for "Dock Speaker".  If a headphone is plugged, the speaker is muted no matter whether speaker volume mixer controls are muted or not.

The same for undocking.  Since "Speaker" and "Dock Speaker" values are kept untouched by docking/undocking action, the mute state is resumed from the auto-muting.

So, all looks OK to me.
Comment 73 jkp 2013-09-06 09:59:13 UTC
OK, Thanks for the info. Your comment answers two of the things which were unexpected to me, but are these also the way they're supposed to be:

* When docked, muting either "Dock Speaker" or "Speaker" mutes the sound.
* Muting "Speaker" adds mutes also to "Master" and "Headphone"

I would expect

* Muting "Speaker" to mute the internal speaker only, not the dock speaker
* Muting "Speaker" to not mute master & headphone

Could well be that these too are consistent with the way alsa muting normally works, like the automute is, and/or not related to the patch, just wanted to point out in case you think it's a problem.
Comment 74 jkp 2013-09-06 10:00:48 UTC
* When docked, muting either "Dock Speaker" or "Speaker" mutes the sound.

Actually this should've been:

* When docked, muting "Speaker" mutes the sound also from the dock speaker.
Comment 75 Takashi Iwai 2013-09-06 10:03:19 UTC
Well, "Speaker" controls only the tablet speaker but not the dock speaker.  Ditto for "Dock Speaker".  "Dock Speaker" doesn't control the tablet speaker.
The auto-muting feature is a different story.
Comment 76 jkp 2013-09-06 10:08:30 UTC
"Well, "Speaker" controls only the tablet speaker but not the dock speaker."

That's what I'm expecting. But what I'm telling as the test results is that muting "Speaker" does mute also the dock speaker. And also adds "M"'s to Master & Headphone. Even after I unmute Master & Headphone, dock speaker remains muted.
Comment 77 jkp 2013-09-06 10:10:31 UTC
To be more exact, there's no sound from dock speaker (when there are no "M"'s at dock speaker control but there are "M"'s at "Speaker" control).
Comment 78 Takashi Iwai 2013-09-06 10:13:46 UTC
This is odd.  How did you achieve it at all?  That is, what is your test procedure?

In other words, does it really happen in the following?
  - amixer -c0 set Master unmute
  - amixer -c0 set Speaker unmute
  - amixer -c0 set "Dock Speaker" unmute

Dock the macchine
  - amixer -c0 set Speaker mute

Then check alsamixer.
Comment 79 jkp 2013-09-06 10:21:15 UTC
Report:

Start state: Everything unmuted, docked.

Undocked.

Geve the following commands in undocked state:

  - amixer -c0 set Master unmute
  - amixer -c0 set Speaker unmute
  - amixer -c0 set "Dock Speaker" unmute

Docked.

Gave the command "amixer -c0 set Speaker mute"

Alsamixer shows:

Master, Headphone, Speaker all are muted ("MM"), Dock speaker unmuted ("OO").

No sound heard when trying sound test.
Comment 80 Takashi Iwai 2013-09-06 10:31:43 UTC
Give alsa-info.sh outputs before and after running "amixer -c0 set Speaker mute".

Also, try to mute "Speaker" via the command below instead.

  amixer -c0 cset name='PCM Playback Switch' 0,0

Does this cause the same effect?

And yes, it does cause the same effect.
Comment 87 jkp 2013-09-06 12:20:21 UTC
Unmodified 3.11 also mutes master & headphones when muting the speaker.
Comment 88 Takashi Iwai 2013-09-06 12:24:55 UTC
Could you stop PulseAudio and test without PA?
Comment 89 jkp 2013-09-06 12:29:46 UTC
You nailed it - kill -stop'd pulseaudio, now speaker with unpatched 3.11 works like expected.
Comment 90 jkp 2013-09-06 12:38:26 UTC
To be more exact, muting the speaker works like expected in the way that it doesn't mute master & headphones.

However, using 3.11 patched with your patch, pulseaudio stopped, after unmuting NID14 when docked, muting the Speaker has no effect, sound is heard from speaker anyway.
Comment 91 Takashi Iwai 2013-09-06 12:41:06 UTC
Because "Speaker" is bound always to the tablet speaker while "Dock Speaker" to the dock speaker.  We can improve the behavior more, but I have no time for that for now...

Though, it's really weird that PulseAudio got so much screwed up.  Since even the unpatched driver shows the behavior, I guess it's a bug of PulseAudio.
Comment 92 jkp 2013-09-06 13:28:18 UTC
By me your patch works well and is ready for inclusion into mainline. Thanks for your work.

Seems to me like there's a small issue with the mute left. I did realize Speaker means the tablet speaker, that's what I was talking about, the tablet speaker is not muted with "Speaker" control when docked. In other words, when docked, muting the Speaker has no effect on the tablet speaker, sound is heard from tablet speaker anyway.

However, muting the tablet speaker with Speaker mute works fine when undocked, and there probably aren't many use cases for the tablet speakers when docked so I don't think the issue has much practical significance. (couple of use cases: if the dock speakers are broken, or if one wants stereo when computer is the shorter side to the user for some reason, but user can probably live without mute in those rare cases..) 

And yes, I agree the mute weirdness looks like a bug of Pulseaudio.
Comment 93 Takashi Iwai 2013-09-06 14:05:39 UTC
OK, I submitted the patch to ML, and it'll be merged to git tree shortly later if no one objects on ML.
Comment 94 jkp 2013-09-17 13:39:58 UTC
Thanks, appears to be in 3.12-rc1.
Comment 95 lovetide 2013-12-16 06:36:04 UTC
I just installed kernel-3.12.5-301.fc20 on Fedora 20, the dock speaker now working. However, the tablet speaker does not work anymore, now the sound is not balanced, left channel is much much louder than right right channel.
Comment 96 Paweł Mikielewicz 2014-08-26 19:32:13 UTC
As soon as I installed ubuntu 14.04 on my asus TX300 i realized that i have sound only from dock, but when I undock, sound switches to tablet. I found a solution propably for lovetide@gg.com too.

Using hdajackretask I was able to get sound from dock and a tablet simultanly.

2.0 channels 4.0 speakers TO DO :
override Pin ID: 0x21 (on my tx300 named: Black Headphone, Right side) to be a speaker

But I wanted to have 4.0 sound system, to get better than Windows.
As soon as Ubuntu default drivers sees a 4.0 system, but cannot play sound from one "row" speakers I started to experiment and get to work

4.0 channels 4.0 speakers TO DO :
In advanced override mode, override Pin ID: 0x21 as 
Connectivity: Internal (seems to make no diffrence setting it other way, but do not leave blank)
Device: Digital Out (After setting this as Speaker, I only have 2.0 Channels, but sounds from all speakers)
Other settings seems to make no diffrence after all

I also added to /etc/modprobe.d at the end:

"options snd-hda-intel model=asus-mode1"

Don't know if this changes anything

Hope that helps.

Comment 98 Raymond 2014-08-27 02:38:16 UTC
alc282 is a 4 channels codec, even when you have two nodes in spec->speaker_out does not imply Max channel =4 when the driver assign same audio output nodes to two speaker nodes

spec->channels-max  should be two times the number of unique dac assigned to speaker instead the number of speaker nodes

for multi channel, the driver only check all line out jacks have same default association to support multi channel but don't need headphone and speaker to have same default association

the badness of two speaker nodes to support 4.0 line out type = speaker is higher than that of line out type = headphone, the headphone assign dac first and the remain dac is shared by two speaker nodes

seem driver treat speaker and dock speaker as 2.1 share same DAC but set channels max= 4

requirements of subwoofer and rear surround is sligthly different since subwoofer with low pass filter only need copy of front signal but rear surround need two dac assign to front and rear speaket

===> Best configuration: lo_type=2, wired=1, mio=1
multi_outs = 21/0/0/0 : 3/0/0/0 (type HP)
   out path: depth=3 :03:0d:21
spk_outs = 1b/14/0/0 : 2/2/0/0
   spk path: depth=3 :02:0c:1b
   spk path: depth=3 :02:0c:14

as both speakers connected to same DAC , it won't support 4 channels in this config
