Public bug reported:
Binary package hint: alsa-utils
When I mute any of channels(Front, Surround, Center, LFE, Side) in alsamixer of
kmix the effect is the same as muting channel Master or all seperately - no
sound at all. In karmic those worked properly. I'm using following entry in
/etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=lenovo-sky power_save=10 power_save_controller=Y
and have loaded following modules:
