Bug Description
On Ubuntu 13.04 after the latest pulseaudio update (1:3.0), my sound keeps breaking intermittently. The problem seems to be related to multiple audio sources playing/pausing at once. The way I can most reliably reproduce it is playing a song in Rhythmbox while getting Pidgin notification sounds; after pausing the song in Rhythmbox, audio stops functioning completely and pulseaudio must be terminated for it to come back. (Sometimes, even after terminating and restarting pulseaudio, sound still does not work until logout/login or reboot.)
I ran pulseaudio with logging enabled and saw that after sound stopped working, this output repeated itself every time I tried to produce a sound:
( 282.746| 3.257) D: [alsa-sink] protocol-native.c: Requesting rewind due to end of underrun.
These errors were also frequent after the malfunction:
( 279.489| 0.000) D: [pulseaudio] module-
( 284.375| 0.000) D: [alsa-sink] sink-input.c: Requesting rewind due to corking
I've attached my entire pulseaudio log. There's a lot there because I threw a lot of sounds at it to reproduce the error, but hopefully it's helpful.
