Public bug reported:
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-suspend-on-idle.c: Sink
alsa_output.pci-0000_00_1b.0.analog-stereo becomes busy.
( 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.
