Comment 9 for bug 235990

I might have a small extra clue here. I just watched pulseaudio hang in the middle of playback (leaving it looping a few milliseconds of sound over and over). In the syslog I caught this message:

Dec 15 10:04:48 inspiron pulseaudio[6157]: protocol-native.c: Failed to push data into queue
Dec 15 10:04:53 inspiron last message repeated 8443 times

I looked through my old syslogs, and this has happened 3 other times over the past week. So it looks like I'm getting this message every time I'm experiencing the hang.
