Sound stops and doesn't work until I restart pulseaudio. You know, the usual. I think some people restart their whole computer and blame their drivers, but restarting pulseaudio alone is what fixes it nine times out of ten.

Interesting. I'd still rather have that problem than the massive, massive problems I tend to have without PulseAudio. Only one app can make sound at a time, can't adjust volume at all, that sort of thing.
