For what is is worth...
My puulseaudio was awful. It used 70% of my CPU tyring to watch a film
in mplayer, etc. This post made me look at the config, and I say there
was a daemon.conf from September and a daemon.conf.rpmnew.
The old one had things like:
nice-level -11
realtime-priority = 5
When I swapped to the rmpnew conf file things got much smoother.
