[mythtv-users] Need sound help

[Stephen Sassman]

I am running mythbuntu 9.10 (Karmic w/ 0.22) For the last week, I have been
unable to get my sound working. I'm not even sure what happened to make it
stop working. I have alsa installed (1.0.22) along with alsa-tools. I
checked all settings on alsamixer. I have tried to get sound from the analog
and digital outs from my onboard sound card. I can hear popping sounds
whenever I change certain settings in alsamixer, but cannot hear the audio.
Even if I unmute the S/PDIF slider and turn volume up to 100, it still
doesn't work. Then, when I go to play a video, the S/PDIF volume goes to
zero and I cannot change it until the video is finished playing.

My best guess is that something is holding the sound card hostage, but I'm
not sure what since this happens even on a freshly booted system. I've tried
installing/uninstalling pulseaudio and esound, but neither of those solved
the problem either. I am out of ideas and ready to reinstall at this point,
but my CD drive is broke so can't do that either. Please help! Thanks!
