PostPosted: Thu Aug 02, 2012 4:40 am    Post subject: snd_hda_intel: timeout mutes frequently, mplayer mutes Reply with quote

On my ThinkPad x201 with intel onboard audio, my formerly working ALSA pulseaudio system is now automatically muting the master and PCM mixer channels. The muting happens on timeout for unused audio (uncertain if there's a fixed timeout), and also with certain audio apps like mplayer (mutes automatically when starting, can not unmute).

Can anyone point me to the proper configuration for current versions of pulseaudio and alsa to suppress this? And if it's a known power saving strategy, then at least suppress when on AC power?

Thanks.

I think I'm having the same problem. After some time the sound just disappears as if it was muted. alsamixer shows none of the channels are actually muted though. This happened today when I was in the middle of watching a video on youtube. If I force unload the snd_hda_* modules and reload snd_hda_intel the sound comes back.

I don't use pulseaudio, and because I switched to KDE, upgraded the kernel, and made some other significant changes to my system last weekend I'm not sure where to start looking.

try and boot with "snd_hda_intel.enable_msi=0" (disables MSI).

That doesn't help here. Sorry, I missed the OP saying that the channels are actually getting set to muted, so I must have a different problem.

I did notice an "auto-mute mode' toggle in alsamixer FWIW.

I think i am getting the same issue here, except that the parts in alsamixer are not muted. Its every time the same issue, rebooting or rmmod snd_hda_intel && modprobe snd_hda_intel fixes the sound for at least 10minutes.
Then the sound dissapears again until reboot or rmmod...

Could some aggressive power saving option be the culprit ?

I tried both, disabling the aggressive power saving part from kernel and activating it with timeout set to 0

That's to automatically turn the main speakers off, when a headphone jack gets plugged in.

Well isn't that fancy.

Still the same problem here after switching back to Xfce. I also regressed to 3.4.2 with no luck. I'll put my alsa-info up here: http://dev.gentoo.org/~dirtyepic/misc/alsa-info.txt

The bad news is this is really starting to affect my YDKJ scores.
The good news is `alias grrnotagain='/etc/init.d/xdm stop && rmmod snd_hda_intel && modprobe snd-hda-intel && /etc/init.d/xdm start'`

Did that line help more then ~10minutes? When i rmmod the module and load it again the sound came back for at least ~10minutes.
I enabled CONFIG_SND_VERBOSE_PRINTK and CONFIG_SND_DEBUG and there is no debug line between a working aplay and then a none working one.
Maybe a ACPI issue?

It depends. If I'm playing audio through the browser or mplayer it can cut out after 5 minutes or 5 hours. Sometimes it cuts out in the middle of a video and sometimes it's already gone when I start playing it. Even stranger is I often leave clementine playing overnight and I almost always have sound when I get home from work (~18hrs later).

I am just testing with speaker-test or aplay and there its every time the same, Headphone jack always work its just that internal speaker. I already tested another older kernel where i had snd_hda_intel built into the kernel (3.2.12)
with no difference...

Have you visited your dmesg logs? I've noticed an hda related kernel oops while testing kernel 3.4.9 once, but I didn't come as far es to try out sound. No sound issues on 3.5.3 though.

Looking at the stable-queue patches after 3.4.9 there is one related to such a crash but it was reverted again after 3.4.10... git.kernel.org

Yeah i activated all debug stuff for this snd_hda_intel, i can see the playing of sound in the logs but then the sound disappears without any hint in the logs.

I tried hda_analyzer there i can see that my internal speaker of the notebook is on Node[0x1f] its set to out, as long as the sound works i am able to enable and disable it with the OUT part. After it disappears i cant to anything in this tool to enable this speaker again. (I can still activate the internal speaker of the Docking station on Node[0x1d] even if the sound disappears again. I really dont have any idea what happens here

I think i found the reason for my problem, as its described here:
http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28769.html

I can temporarily enable the sound again with hda-verb but it then disappears again after 1-2 minutes.

I been emailing Takashi to see if we could get a possible resolution to the problem. He has contacted conexant and this is their reply:

"The information you provided from the customer's machine indicates that the Class-D internal speaker amplifier over-temperature protection mechanism has tripped. This does not cause the node to go to D3, however it would cause the audio to stop playing from the internal speakers.

There are no power saving, or other, features *in the hardware* that would put a node into D3--changing the power state like that is something we leave to the software drivers. I tried a few scenarios on the bench and was not able to duplication a situation where the part went into D3 on its own.

This all said, there really is not anything else we can suggest checking for over-temp fault, the laptop owner should probably work the issue directly with Lenovo."


Just goes to show conexant will push everything off to the vendors just to prevent admitting they have a problem. Hope this helps open everyones eyes to just how bad the support from conexant is.

On my system any use of mplayer trips the sound off without delay. Perhaps that might be useful to repeatably observe hardware state transition.

Thanks,
Jeff

Well I just called and raised enough hell with lenovo they are sending a tech out to replace both boards and spearkers in my t410. I will let you all know if it fixes the problems just as soon as they are complete, it will be a few days before they arrive so will post back soon as I have an answer.

update : They have replaced the board in laptop and sound is working perfectly again. This is a design flaw in the conexant chip that prevents it from cooling properly.

Hi, I was researching the problem again and saw that you found my post on the alsa-user list. Sorry for resurrecting this thread, but since some time has passed, is everything still looking good with your new board and speakers? If so, I'll contact Lenovo as well. Thanks a lot!
