Hi, recently audio stopped working. It maybe after the upgrade of alsa [2010-07-23 07:19] installed alsa-utils (1.0.23-2), but not sure. It is a SiS SI7012 Chip: C-Media Electronics CMI9739 and has been working for a while without problems.
I checked in xfce4-mixer and found PCM muted. Tried to unmute, but it just muted itself again. Tried the same in alsamixer and could not unmute. Also tried as root. I am member of audio
I have tried restarting alsa as root /etc/rc.d/alsa restart and got this
/usr/sbin/alsactl: set_control:1388: Cannot write control '2:0:0:PCM Playback Volume:0' : Operation not permitted
Also as root amixer sset PCM 90% unmute -d
amixer: Invalid command!
Tried on the IRC with a few suggestions, tried setting card options again, but still dead. Hoping someone here may have some clues.
Dan

Did you try re-running "alsaconf" (as root) ?
Also, read through this and try anything there that seems reasonable to your situation: http://wiki.archlinux.org/index.php/Alsa .

I tried running alsaconf (root) and that does not change things, but I have made some progress. It seems that stopping X and running alsamixer from a tty and un-muting PCM fixes the problem. It is still fixed going back into a desktop. After rebooting and then going into XFCE once again PCM is muted an cannot un-mute. Weird!

Try running "amixer" from the command line:
amixer -q set PCM mute
amixer -q set PCM unmute
You could bind those commands to a keystroke also, if they work for you...

Yeah, I tried that as per the first post and it gives an error amixer: Invalid command!.
Still it works outside of XFCE. It works at tty and I just tried going into openbox. so it must be something XFCE specific. I'll look at what I have starting up and try and figure it out.

amixer set PCM 85% unmute

Either command
amixer -q set PCM mute
or
amixer set PCM 85% unmute
give error "amixer: Invalid command!", but only in XFCE. It works at tty or even in openbox. Must be something with XFCE.
