Re: pulseaudio causing crashing of applications

Hi folks,

Is anyone else seeing regular crashing of applications like pidgin, mplayer or xine caused by pulseaudio? Did anybody manage to get useful backtraces out of this?

Thanks,

I just had an issue with rhythmbox locking up while playing through pulseaudio. It locked only when I switched to VT1 where root was logged in, and it immediately stopped playing and froze. I've got the backtrace for all threads, but the top few are below. The rest is rather long so I won't post it yet. I haven't had rhythmbox do this before tonight.

Usually it will stop playing through the sink device (it is still trying to) until returning to the login that is running rhythmbox, but this time it actually froze and did not keep streaming to the sink.
