kernels 3.2.2, 3.2.4 alsa and missed `mute' capability?

After upgrade to 3.2.2 or 3.2.4

$ amixer set <whatever> mute

results in an error message about incorrect `mute' command. I run alsamixer and it looks like there is no `mute' capability for my sound card: http://mini.pw.edu.pl/~kozlowsm/noalsa.png

A very standard ThinkPad T400...

Just use:

amixer -q sset Master 0%

Don't be kidding ;-) I can reduce volume to 0, but reducing the sound volume != muting. It's a workaround and I'm asking about the solution.

Moreover I can't find any error / reason. Everything seems to work fine except...

This is strange, indeed. Just a shot in the dark: have you tried loading the sound module (snd-hda-intel) with a model parameter? You can find all available models here: http://www.kernel.org/doc/Documentation … Models.txt. Your chip (CX20561 Hermosa) is not listed there, but somewhere i read that it's the same as the Conexant 5051. So the models to try would be:

Conexant 5051
=============
  laptop	Basic Laptop config (default)
  hp		HP Spartan laptop
  hp-dv6736	HP dv6736
  hp-f700	HP Compaq Presario F700
  ideapad	Lenovo IdeaPad laptop
  lenovo-x200	Lenovo X200 laptop
  toshiba	Toshiba Satellite M300

Maybe this helps to fix your mixer thing.

I've run into same problem recently - try model=ideapad. Works well for my T400 and kernel 3.2.5

It works (3.2.6)!
Anyway: my T400 wouldn't be happy if it knew it's called `ideapad'...
