Hi all,

i recently installed FC11 and tried to start jackd with qjackctl.
I get many dropouts and seem to have no permission to
acquire realtime for jack. My user-account is in all pulse* groups
and in group audio. I did not install pulse - do i have to???
All works fine under FC10. Any ideas? Here is (part of) the output of qjackctl:

...
JACK server starting in realtime mode with priority 89
