Sound stops working after a while on 12.04

[tekstr1der]

Binary package hint: pulseaudio

After some random amount of time, sound is lost completely in Natty. The applications outputting sounds continue to run as normal.

Forcing suspend/resume brings audio back.

Can you reproduce this symptom while using https://wiki.ubuntu.com/PulseAudio/Log?

[ill (illumilore)]

This happens to me as well. Suspending and resuming will fix the sound, but killing and restarting pulseaudio will not.

Seems to be affecting 12.10 as well.
