Okay, one sec: I'm seeing the same behavior on a box that I upgraded from Debian
Lenny to Squeeze a couple of days ago.

After debugging, I see that the problem is caused by PulseAudio which blocks
*after a few writes* when the audio device is busy. It looks like the PulseAudio
buffers gets filled, and then pa_simple_write() just deadlocks.

If I release the device (eg, exits Rezound, etc..) then it works fine.

This is really unexpected.

Have anybody had such troubles with PulseAudio 0.9.21 on Squeeze or similar?
