pulse audio causes app freeze (f10)

I've been having intermittent problems with applications freezing, and I've finally had a string of consistent failures that lead me to suspect that pulse audio causes apps to freeze when they are expecting to play a sound but something about making the sound fails.

Specifically, I'm running gnome under f10 with the pulse audio with the famous mod to default.pa:

load-module module-hal-detect tsched=0

I'm using the proprietary nVidia driver from PRMfusion. It's a 64-bit machine.
The app in question is gedit, which wants to make sound when doing a search, inserting date and time, and many other things.

(1) When the sounds arrive, there's never a freeze
(2) When there was sound at launch, the if the sounds stop coming, there's a freeze.
(3) One time, there was a partial sound, and instantly there was a freeze.

These sounds are generally associated with dialog boxes, but there may have been a few cases where it wasn't.

I can go ahead and kill the app and restart. I eventually get lucky most of the time. Otherwise I have to restart X. I may try disabling such sounds and see what happens.

Does anyone else have this problem?

OK, it's been a few days and my life has gotten a lot smoother. Nothing like the freezes described above.

What I did was System > Preferences > Hardware > Sounds > Sound Tabs uncheck play alerts and sound effects. As this appears to work, I must point not the finger at pulse audio per se, but at whatever mis-handles these event.
