Hey list

sporadically, I have problems with alsa on my netbook. After booting,
alsamixer does not show a PCM channel. So I fire up cmus, start playing
and then the channel appears.

The other problem is that sometimes I can't change volume of the PCM
channel, neither in cmus nor with alsamixer. I can then only alter the
master channel. Last time that happened, PCM was stuck at 100% (don't
remember whether it's always 100%).

Does anyone have a clue what the problem here is (and possible how to
solve it)?
