[Karmic stac9227 regression] No sound after upgrade from Jaunty to Karmic

Can you hear output from "speaker-test -c2 -Dplug:front"?

Public bug reported:

Binary package hint: pulseaudio

I can't tell if this is a duplicate or not, but yesterday running an up
to date Jaunty everything was fine, then I upgraded to Karmic (via
update-manager -d), rebooted and there is no sound. I tried unmuting
things with alsamixer and the gnome mixer, stopping and starting
pulseaudio, removing ~/.pulse but nothing worked. :( I'm not sure where
to go from here as I don't know the sound stack very well.

No sound after upgrade from Jaunty to Karmic

You received this bug notification because you are a member of Ubuntu
Audio Team, which is subscribed to pulseaudio in ubuntu.

I have been using karmic for some time now and I used to have sound. Yesterday, I updated the system and now the sound is no longer working on reboot. I think it may be related to this bug (although it is not an upgrade from Jaunty) because I have the same audio card.

Pulseaudio was updated yesterday I believe:

pulseaudio (1:0.9.15-4ubuntu2)
SECURITY UPDATE: root escalation from BIND_NOW re-execution.
0040-do-not-exec-for-bindnow.patch: use -Wl,-z,now instead of performing a racey re-exec.
CVE-2009-1894

Reverting to pulseaudio 0.9.14-0ubuntu20 did not fix the problem on my laptop. I don't think pulseaudio is the problem, at least not for me.

I reverted gstreamer to 0.10.23 too but it still did not help.

However, I noticed that I have sound with mplayer. It seems like only gnome apps are affected maybe.

Please ignore my messages. My sound is back. It turns out it was simply a sound settings problem. Apparently my PCM level was reset to 0 (probably by one of the updates?).

Unfortunately, no sound:

Something has already grabbed hw:0. Try:

pkill pulseaudio; speaker-test -c2 -Dplug:front

(See also sudo fuser -v /dev/dsp* /dev/snd/*)

Both 'Center' and 'LFE' are also muted, but I have not looked at your
codec output yet.

Hmmm, still no sound. pkill pulseaudio wasn't good enough cause pulseaudio kept restarting. I saw this in .xsession-errors:
** (gnome-volume-control-applet:5093): WARNING **: Connection failed, reconnecting...

** (gnome-volume-control-applet:5093): WARNING **: Unable to get default source

I did have a volume control applet open and then one in the notification area. I removed the applet, then fiddled with the notification area one. Eventually it went away and I got this in .xsession-errors:
** (gnome-volume-control:18676): WARNING **: Unable to find stream for bar
Assertion 'pa_atomic_load(&(c)->_ref) >= 1' failed at pulse/ext-stream-restore.c:202, function pa_ext_stream_restore_write(). Aborting.

At this point I could kill pulseaudio and it wouldn't restart. So I did:
$ speaker-test -c2 -Dplug:front

speaker-test 1.0.20

After this, I noticed that pulseaudio had restarted itself. I checked /var/log/user.log and see:

Jul 18 15:56:23 severus pulseaudio[18671]: alsa-source.c: We were woken up with POLLIN set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

So this seems it is likely it, but I don't know how to proceed. Please advise. Thanks!

Those messages are not related to your audio being muted, however.

Try disabling autospawn temporarily:
echo "autospawn = no" > ~/.pulse/client.conf && killall pulseaudio &&
speaker-test -c2 -Dplug:front

(To revert to stock behavior, just rm ~/.pulse/client.conf)

Ok, that worked to stop autospawn, but still no sound:

$ echo "autospawn = no" > ~/.pulse/client.conf && killall pulseaudio &&

Have you tried removing the state file? I think I missed a step when I let
you know on irc. You need:

sudo /sbin/alsa force-unload && sudo rm /var/lib/alsa/asound.state

then reboot

To avoid overloading the term "input", do you mean the front
microphone ("input") jack, or do you mean the headphone out jack? If
the former, see:

I'm sorry. The front of the computer has two jacks-- a microphone and a headphone. The speakers are connected to the headphone jack. This jack showed up as 'Front' in the mixer in Jaunty.

To help pinpoint whether this is a driver regression, please try model=ref:

sudo /sbin/alsa force-unload && sudo modprobe snd-hda-intel model=ref && speaker-test -c2 -Dplug:front

Still no sound. As before, I had to run /sbin/alsa force-unload twice to unload all the modules. Here is the output:

I'm not sure why this is still Incomplete, as I think I gave everything asked of me.

That said, I decided to boot into kernel 2.6.28-13.45-generic (ie, Jaunty's kernel) on my up to date Karmic system, and I have sound with:
$ paplay /usr/share/sounds/ubuntu/stereo/desktop-login.ogg

Thanks; we'll need to git bisect next.

As Daniel knows, I tried several kernels going back to http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.6/ and still no sound.

I am out of town, but when I get home I'll run 'apport-collect -p linux' and verify against the -5 kernel.

This bug affects me too - same soundcard:

card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I have good sound in the speakers but no sound from the headphone jack. This was always the case for me in all previous releases so I used to add

options snd-hda-intel model=vaio

to /etc/modprobe.d/alsa-base.conf

I tried that again this time but still no sound from the headphones. I have a Sony Vaio VGN-FZ21M

Any update on this ?
Eagerly waiting for a solution.

I finally upgraded this machine to lucid, and am still have the problem.

Approved the Karmic task and added the Lucid one. Since Karmic released with this bug, feel free to adjust the Karmic task as necessary.

Please attach /proc/asound/card*/codec* from Lucid.

The same bug affected my Karmic Koala. Sound is turned off. It's happened after upgrading Alsa → alsa-base (1.0.20+dfsg-1ubuntu5) to 1.0.22.1+dfsg-0ubuntu3~ricotz1; and pulseaudio → pulseaudio (1:0.9.19-0ubuntu4.1) to 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu11~~karmic~ubuntuaudiodev1).
My kernel is : 2.6.32-15-generic.
Then I tried to downgrade to the previous version, but the sound hasn't returned.

Does it needs an apport-collect -p linux from lucid too?

I can provide if, just let me know.

Now, it seems to work :-) Great thanks for everyone who was working on that bug!
