I've noticed this happening sometime while using Hardy. Originally sound worked perfectly since I installed Hardy.
My sound card is fully supported ( Intel 82801EB/ER AC'97 Audio Controller) and the only device which Gutsy previously had problems with selecting as default audio output, was my usb phone (C-Media Electronics, Inc. Audio Adapter [Planet UP-100, Genius G-Talk]), but now in Hardy, that minor problem doesn't happen.
So my audio worked really good until one day (I was looking at a flash video on youtube), I noticed that sound didn't play. At first I thought it was linked to the buggy Flash plugin. But then noticed that no other application was able to produce sound.
So after fiddling around various settings, reselecting Alsa instead of PulseAudio solved my whole sound problem.
I sometimes re-enable the PulseAudio setting, but with the same results: it works for a couple of days, and after that sound doesn't play any more.
Binary package hint: pulseaudio
