Upgraded to 10.04 and now I have a stuttering problem with music played over Rhythmbox.

I have added the -VVV flag and I get these kind of messages:

I have also seen the wireless noise floor messages although not today.

I have added my name to the pulse and pulse-access group. There is no pulse-rt group (?)

I added the following line to /etc/pulse/client.conf and restarted

extra-arguments = --log-target=syslog --realtime=1 --high-priority=1 --fail=1 -vvv

I am currently using an external USB DAC, a total bithead.
