Comment 8 for bug 669535

I attached four log files. I notice many rtkit-daemon error messages in syslog. The process 1962 mentioned in those error messages at the very bottom of syslog is a pulseaudio process.

Also note, I upgraded to Ubuntu 10.10 today but I still see the issue. I believe the system is now using the proprietary 10.8 Catalyst driver included with Ubuntu.
