Default Kernel 3.1.6 and loss of sound

Hello list,

*

Today I upgraded my kernel from 3.0.6 to 3.1.6 and promptly lost sound. This motherboard has Intel HDA. All the required modules are loaded, and I hear a thud as they're loaded, but alsaconf can't find the device.

*

I tried recompiling all the alsa drivers into the kernel instead of as modules but it made no difference.

*

Has anyone a fix for this?

*

I think the first step for something like this is to run
/usr/bin/alsa-info to get some debugging detail.


In other news...So 3.1.6 just went stable for amd64. I wonder what's
special about that one that wasn't met by 3.0.{13|14} or 3.1.[0-5].

I just did a quick update on my wife's machine which also uses Intel
HDA and have sound in KDE so at least it's not a generic problem.

I guess you're going to need to provide some debug info. Maybe try a
complete power down and not just a warm boot. Not finding the device
at all is problematic. What's in lspci, etc.?

Post back with more info.

Power cycle complete - no difference. Switching back to kernel 3.0.6 I now have no sound there either!

*

Lspci shows the device ok. Output of alsa-info attached.

Peter, according to your amixer output 'Master Front' is set to 0%. Maybe this is your problem?

Well spotted, both you and Michael. However, that's not /the/ problem. Setting the master volume to 100% just gave me a faint hiss in the speakers; no real sound, and no device detected by alsaconf.

Well spotted, both you and Michael. However, that's not /the/ problem.
Setting the master volume to 100% just gave me a faint hiss in the
speakers; no real sound, and no device detected by alsaconf.


I'm inclined to think you have something in your asoundrc (either
system-wide or user-local) that's shunting ALSA clients over to Pulse,
and that Pulse has a misconfiguration.


FWIW, alsaconf doesn't see my sound cards, either. Here's what I've got:

kaylee shortcircuit # lspci -k|grep -i -A2 audio

Neither of those exists on my system.

/etc/pulse/daemon.conf hasn't changed since 8 Dec.

This is mine:

You mentioned that switching back to the old kernel doesn't fix the
audio, but have you tried the old kernel since changing the volume
control? Another data point, at least.

If you still don't have sound using the old kernel, then I think the
problem must lie with some other recently updated package, no?

One other data point to compare:

$ls -l /dev/snd
