Hi,

Is this reproducible ? We released a fix for a similar issue Wednesday last week.

I need more info here. Was it a USB device that you were using at the time of the crash ? Can it reproduce it ?
Marking incomplete until more info is given.

No, I am using a Creative SB 5.1 VX Soundcard and did set the default audio output to it and listened to the samples to check if it works.
It will try to reproduce it when I get the time.

Was your precise up to date when the crash occurred on the 15th ?
We did release a fix through pulseaudio on the 11th which resolved a crash that produced a stack trace very similar to that.
