Description of problem:
When I play music files or CDs, after a short while pulseaudio consumes +80% of CPU and the music plays at a much faster rate (like someone has hit the fast forward button).

Version-Release number of selected component (if applicable):
All latest F11 updates applied as of today.

How reproducible:
Play some music, say Rhythmbox and after a few seconds, the above happens.

Steps to Reproduce:
1. boot system
2. play music files or a music CD via rhythmbox.
3. 
  
Actual results:
Music appears to go in fast forward mode and CPU util goes through the roof.

Expected results:
Able to play music.

Additional info:
See attached from /var/log/messages.
After searching the www, I came across this work-a-round which allows me to listen to music at normal speed :) and is reasonably stable.

diff default.pa.orig default.pa.good

> load-module module-hal-detect tsched=0


Another 'feature' with rythmbox, is that if I skip to the next song, the volume of sound either decreases or ends up muted.

I hope this info means something to you and you are able to help.
Many thanks.

snd_pcm_delay/snd_pcm_avail is overflowing. This is a driver bug.
