There are several apps, and used to be several more, that still do not 
play nice with pulseaudio.

For me, pidgin was the biggest culprit until a recent update.

What happened for me, was that apps that professed support for 
pulseaudio, such as amarok, would spin and cause the pulseaudio daemon 
to die at some random beep from pidgin.  Once the deamon died, CPU usage 
returned to normal, but no more sound.

Restarting pulseaudio always fixed it, but the occurrence was random; 5 
minutes; two days?

Since the update to pidgin-2.5.2-6.fc10.x86_64, those have stopped. 

However, about the same time, we got an upgrade to amarok that I could 
not tolerate.  I have since switched to rhythmbox, but it pauses at 
virtually all focus changes into or out of firefox and thunderbird.  I 
suspect that compiz is still struggling with those two apps, as they are 
difficult to move around the screen for me.

But in any case, as Frank Cox has pointed out, the pulseaudio daemon is 
likely your issue, and can be restarted.


Good Luck!
