alsa sound fades out when headphones are plugged in until you inaudible

[D B]

Binary package hint: alsa-base

Sound works fine from the speakers, but when headphones are plugged in, sound gradually diminishes until it is silent. Unplugging the headphones leaves it silent on the speakers. Reboot resets the position and sound is fine until 'phones plugged in.

My card is a "Sigmatel STAC9227" in a Dell Dimension e520 desktop but it seems to affect similar cards.

More info of the problem: http://ubuntuforums.org/showthread.php?t=913328&page=3

To address this, you can restart alsa and pulseaudio:

 sudo alsa force-reload
 pulseaudio

Workaround :
alt-f2
gksudo gedit /etc/modprobe.d/alsa-base.conf
add "options snd-hda-intel model=3stack" to end of file (without quotes), save
reboot

[D B (eburner)]

Adding "options snd-hda-intel model=dell-3stack" to the bottom of my "/etc/modprobe.d/alsa-base" did not fix it in my case.

Adding "options snd-hda-intel model=dell-3stack" to the bottom of my "/etc/modprobe.d/alsa-base" did not fix it in my case, either.

Also DellE520, Sigmatel9227.

[ubername (ubername)]

This problem seems to have gone away with various recent upgrades, but I don't know what fixed it for me.

[D B (eburner)]

Still a problem here with all the latest updates. ubername, you do anything else?

[Daniel T Chen (crimsun)]

Please execute the alsa-info.sh script referenced from https://wiki.ubuntu.com/DebuggingSoundProblems and attach the URL here.

Please note that any possible fix will /not/ be in 8.10. -updates is possible but more likely 9.04.

Hi, I have had the same problem. I ran the alsa-info script and the output can be found here

http://www.alsa-project.org/db/?f=dbdf44b7f7a1ff7fc634cef975b7089fddd19736

The sound works if you keep the same speakers plugged in from boot, but as soon as I unplug the speakers/headphones and reconnect I get the fading effect.

[jdbausch (jdbausch)]

I'd just like to write a "me too" to this issue:

"The sound works if you keep the same speakers plugged in from boot, but as soon as I unplug the speakers/headphones and reconnect I get the fading effect."

after upgrading to Intrepid from hardy. the suggested fixes have not worked for me.

I have a Dimension e521

[D B (eburner)]

still not working in Jaunty Alpha 2 with 2.6.28-4-generic

Also not working in Jaunty (with updates to 09/02/09 - whatever alpha version that makes it)

[Gari Araolaza (garaolaza)]

Hi, no news from me.

Just to confirm this error in three Dell Dimension E520 and Ubuntu 8.10 systems.

[Mikhail Moussikhine (belamiru)]

I also confirm the same effect with the latest Ubuntu 9.04 and HT Omega Claro Halo.

Alsa info:
http://www.alsa-project.org/db/?f=d096043dca1f471400f1d8d2c17bfdd57f3f9524

I tried to upgrade to 1.0.19 drivers and the result is still the same. Sound fades out in about 5 sec. Furthermore, I was not able to get any sound from any other program but "Sound Preferences" Test Playback.

[laubster (k-launchpad-laubster-org)]

me too; DellE520, Sigmatel9227. When the headphones are unplugged before the fade is complete, the volume remains stable through the speakers though at its lower level; when the headphones are plugged in again, the fade resumes.

Brian, you're using the wrong model quirk. You should be using
model=3stack, not model=model=hp-m4. (Note your extra "model=".)

[Brian Beck (brian-beck)]

I noticed that after I posted, and made the change and reboot my computer. Still no sound. Here's a re-run of the alsa-info.sh script:

[Brian Beck (brian-beck)]

Daniel, I looked at your post again, and adding:

options snd-hda-intel model=3stack

to the bottom of /etc/modprobe.d/alsa-base.conf does in fact fix the problem!

Thank you so much,
Brian

[Daniel T Chen (crimsun)]

Mikhail Moussikhine, you're using a separate codec (not even HDA but AC'97). Please file a separate bug so that you don't confuse people further.

[Mikhail Moussikhine (belamiru)]

Well, duh. I did say that in my post.

The name of the bug does not specify that it is HDA specific. I use oxygen driver. And I have _exactly_ the same effect.

Ubuntu 9.04 is out. Plug-in headphones. Sound fades out in 5 sec. I will not confuse your further, though. Thanks.

[Fabio Barros (fgomesbarros-gmail)]

I also added "options snd-hda-intel model=3stack" to the bottom of /etc/modprobe.d/alsa-base.conf and the problem was fixed.

[Everthon Valadão (valadao)]

@Daniel T Chen: the "options snd-hda-intel model=3stack" trick fixed here too, thanks!

[Daniel T Chen (crimsun)]

Derek, can you run the alsa-info.sh script to attach your audio hardware info to this bug report? (Alternately, if you're using Jaunty, just use "apport-collect -p alsa-base 279478".)

Everthon, if you're using Jaunty, can you also use "apport-collect -p alsa-base 279478", please?

The apport-collect crashed on me but upon testing this since Jaunty's release, it works here!

I do have the 3stack option in /etc/modprobe.d/alsa-base.conf still, though I'm not sure if it does anything.

[D B (eburner)]

I think we're all agreed it's working! Thanks for helping me rediscover my headphones Daniel! Odd to communicate with you on launchpad vs irc though. Cheers!

[Daniel T Chen (crimsun)]

This bug is not fixed yet, as the quirk table has not been updated yet.

Furthermore, everyone still needing to use model=3stack has to manually override the quirk table entries.

[Steve R. (streeder)]

DellE520, Sigmatel9227, Jaunty.
Adding "options snd-hda-intel model=dell-3stack" did not work.
Adding "options snd-hda-intel model=3stack" did.

I realize that most people recommended the latter, but a few people threw the 'dell' in there.

[jtuchscherer (jtuchscherer)]

I just did a fresh install of Jaunty 64Bit and I needed to add this line to the alsa-base.conf. Isn't there a way to add this line by default? Otherwise everybody with this problem is required to find this bug report and to do the change manually.

[Everthon Valadão (valadao)]

Still bugged in Karmic final release... really? Six months and they didn't incorporate the incredibly easy fix into Ubuntu, so we have to manually override the quirk table entries. BTW, just type

   sudo bash -c "echo 'options snd-hda-intel model=3stack' >> /etc/modprobe.d/alsa-base.conf"

to fix your headphone.

[Tchalvak (tchalvak)]

In the latest Karmic Release:

I also added "options snd-hda-intel model=3stack" to the bottom of /etc/modprobe.d/alsa-base.conf and the problem was fixed.

@jdbausch Are you saying that model=dell-3stack does *not* work
properly? Are you using the latest bios for your board?

[jdbausch (jdbausch)]

Sorry if I was unclear.

I was just providing the detail that for my dell dimension E521 installing Karmic produced this issue.

and adding
"options snd-hda-intel model=3stack"
to /etc/modprobe.d/alsa-base.conf

fixed it

Right, but does model=dell-3stack *also* work?

[jdbausch (jdbausch)]

it was a few days back, and in a flurry of installs / reboots, but I'm almost certain that "model=dell-3stack" did not work for me.

Would you mind verifying that it doesn't? I can't send a patch
upstream without some verification...

[jdbausch (jdbausch)]

Confirmed:
on my dimension e521

"options snd-hda-intel model=dell-3stack" produced the fading out when front headphone jack is inserted

"options snd-hda-intel model=3stack" works correctly

[Daniel T Chen (crimsun)]

Thanks, working on a patch now.

The solution with model=3stack used to work on 8.10 and 9.04 for me (it's a long time bug for me)

On 9.10, one of my machines works fine (not sure if it is a e520 or e521, upgraded from 9.04), but it doesn't work on a fresh 9.10 install on a Dimension E520.

It's even worse. Before 9.10, the problem showed up when I plugged in headphones. If I rebooted with headphones plugged in, sound worked well. Now, it happens when the headphones are plugged in.

[Gari Araolaza (garaolaza)]

Please forgive me for spamming this way. It's the first time that I used apport-collected, and now I don't know how to delete the comments.

I confirm that the model=3stack workaround works in both machines. I didn't work this morning, now it works well.

Upstream has asked everyone experiencing these symptoms to try the latest daily snapshot. Because we don't have the latest daily stable snap in Ubuntu 9.10 or 10.04, please do the following if you're experiencing either Derek's symptom (i.e., you need model=3stack to avoid the volume diminishing to inaudible) or Leann's symptom (i.e., you need model=3stack to have jack sense properly working):

* Remove the manually added model=3stack quirk in /etc/modprobe.d/alsa-base.conf (or wherever you added it)
* Install linux-backports-modules-alsa-karmic-generic
* Reboot
* Verify that the symptom remains reproducible
* Use apport-collect -p alsa-base 279478 (note that you should do this step regardless whether it's reproducible)
* If reproducible, purge linux-backports-modules-alsa-2.6.31-14-generic, then download and compile http://www.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-20091105.tar.bz2, and repeat the previous three steps (reboot, verify, and use apport-collect)

I reproduce the problem installing linux-backports-modules-alsa-karmic-generic.

The sound works fine downloading and copiling the alsa driver. Apport information follows

Hi Daniel,

Sorry for the delay with my feedback. I've done the following and verified that jack sense is working. I'll attach my /proc/asound/card*/codec* info. I'll also attach my /proc/asound/card*/codec* info when passing in probe_only=1.

1) Made sure any model quirks have been removed from alsa-base.conf:

ogasawara@emiko:~$ grep -n "snd-hda-intel" /etc/modprobe.d/alsa-base.conf
42:options snd-hda-intel power_save=10 power_save_controller=N

2) Installed linux-backports-modules-alsa-karmic-generic (note I'm running a bleeding edge pre karmic-proposed kernel hence the ~pre1 in the version)

ogasawara@emiko:~$ apt-cache policy linux-backports-modules-alsa-karmic-generic
linux-backports-modules-alsa-karmic-generic:
  Installed: 2.6.31.16.29~pre1
  Candidate: 2.6.31.16.29~pre1
  Version table:
 *** 2.6.31.16.29~pre1 0
        500 http://ppa.launchpad.net karmic/main Packages
        100 /var/lib/dpkg/status
     2.6.31.14.27 0
        500 http://us.archive.ubuntu.com karmic/universe Packages

3) Rebooted (again note I'm running a bleeding edge pre karmic-proposed kernel)

ogasawara@emiko:~$ uname -a
Linux emiko 2.6.31-16-generic #50~pre1-Ubuntu SMP Thu Nov 5 17:34:39 UTC 2009 i686 GNU/Linux

ogasawara@emiko:~$ cat /proc/version_signature
Ubuntu 2.6.31-16.50~pre1-generic

4) Verify sound is working and jack sense is properly working.

[Leann Ogasawara (leannogasawara)]

Adding proc/asound/card*/codec* info when passing in probe_only=1

ogasawara@emiko:~$ grep -n "snd-hda-intel" /etc/modprobe.d/alsa-base.conf
42:options snd-hda-intel power_save=10 power_save_controller=N probe_only=1

[helpdeskdan (helpdeskdan-gmail)]

Upgraded to Alsa 1.0.21 & added options snd-hda-intel model=ref & removed all other snd-hda-intel lines. This worked. 3stack apparently does NOT work on all e520's STAC92xx.

Getting very tired of having to fix Alsa every time I upgrade Ubuntu.

[Daniel T Chen (crimsun)]

@helpdeskdan
We've already resolved this in alsa-driver git.

[Daniel T Chen (crimsun)]

Resolved in Lucid.

Already fixed in linux-backports-modules-2.6.31 (wait for the new one
based on 1.0.22.1)

[bvlad (bernard-banks)]

I have a Dell e520 with Ubuntu 9.10. I had the sound fading issue through headphones, but I did the following that was mentioned in the original post and it seems to have fixed it:

Workaround :
alt-f2
gksudo gedit /etc/modprobe.d/alsa-base.conf
add "options snd-hda-intel model=3stack" to end of file (without quotes), save
reboot

[Daniel T Chen (crimsun)]

That model quirk workaround is incorrect. We've fixed it in Lucid (and
in the daily linux-alsa-driver-modules builds in
ppa:ubuntu-audio-dev).
