Hi All,
after kernel upgrade (3.4.9-gentoo) I'm having troubles with playing video files using mplayer.

mplayer says:
Code:
[AO_ALSA] Unable to find simple control 'PCM',0.
[AO_ALSA] Unable to find simple control 'PCM',0.
[Mixer] No hardware mixing, inserting volume filter.


And I'm not able to adjust the volume using 0,9 keys (I can do it using alsamixer) and mplayer hungs.

root # lspci | grep Aud
Code:
00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA)


root # cat /etc/modprobe.d/alsa.conf
Code:
options snd-hda-intel model=generic
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel


How to fix it? It's been second day I'm playing with it...

Does it work without that modprobe workaround?
