Comment 41 for bug 288093

Yes, sorry on that one, it appears I swapped "Intrepid" and "Jaunty" while writing my previous comment. I am currently using Jaunty, not Intrepid.
As for the latest comment, no, Flash does not reconnect to PulseAudio unlike other apps. Of course, this is Flash's problem, not PA's, but there should be no reason to reconnect in the first place - in other words, PA shouldn't hang.
I just experienced a worse case of this bug. After pausing a Flash video on YouTube, no more audio could be played in the system. Sure enough, pulseaudio wasn't running. That means it didn't only hang, but crash without restarting for a whole two minutes (the time it took before I could play audio again). The only messages from pulseaudio in /var/log/messages (for that matter, the *only* messages in /var/log/messages) are more than 15 minutes older than the time of the crash:
