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. <br>
<br>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!<br>
