Reassigning to pulseaudio and confirming -- I recall seeing this issue sometime back. Restarting pulseaudio makes it all work again.

On the latest updated 11.04, something goes wrong with the sound system so that all applications (e.g. Banshee, Rhythmbox, Google voice, etc) no longer produce sensible sound until the next reboot. Voices sound like crazy robots; music sounds highly metallic. I believe this happens after a one-time stress on the RAM, ie when my memory usage goes beyond the RAM (to use swap) just once, this occurs and cannot be fixed by restarting applications or fiddling with sound settings.
