Bug Description

It rarely stop by itself, if I'm only listening to music it can work for hours. However, most of the time when I come to work in the morning I find out the sound isn't working. Not a single sound will come out of my machine until I either perform a alsa force-reload or reboot.

I think I noticed a pattern.

First I listen to music on hypem.com, then after a while hit pause and either go to lunch or go home. If a Flash animation is left open and is outputting sound, even if paused, I'm 90% sure to find the sound server crashed when I come back.

I get no error messages, just the absence of sound. Some applications, like totem, disable the sound buttons like if it was incapable of accessing the sound server.

Another annoying thing, when I force-reload alsa, every application accessing the sound server (even when it doesn't work) crashes and close instantly. Even Firefox can't recover and forget the opened tabs and starts a new session when restarted.

I use Ubuntu since Edgy and I never had any sound problems until Pulseaudio was introduced.. I don't know if there is a correlation, but it's suspicious and deadly annoying.
