In my case, I identified the source of my sound problems with Pulseaudio: I had installed the "randomsound" package, and it conflicts with Pulseaudio and causes the audio controller to stop being recognized. If I remember correctly there is already a bug somewhere in Launchpad for this (I think I filed it but I don't remember).

Status in “pulseaudio” package in Ubuntu: New Bug description: Binary package hint: pulseaudio There is no audio in Lucid AMD64 with this audio controller. The sound worked when I first installed, then simply stopped working. I can get sound if I forcibly remove Pulseaudio, but of course I'd rather not take that drastic step. I am only mentioning it because it might help debug the issue. When I look in my sound properties under Hardware, I see a "Dummy Output" device, but the real hardware is not found. Again, sound is completely unusable (nonexistent) unless I remove Pulseaudio.
