It did this for me too. Awful.
It used 70% of my CPU trying to watch a film in mplayer, etc. This on a
single-core 2GHz laptop.
But I just found, in /etc/pulse, 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 better.
