Any application using phonon-xine and NOT outputting any video produces around 900 wakeups per second, I have no video only material, so maybe it's the same there to, just the other way round.

Reproduce:

Any phonon media player should be suitable, I am using dragonplayer as it plays video and audio and is simple.
The wakeups/second get reported by powertop from intel www.lesswatts.org/projects/powertop/ 

Video with audio leads to ~ 70 wakeups/second (fine)
audio only (mp3) leads to ~900 wakeups/second (ugly)


Also happens with amarok2, didn't try other phonon using software.

The interesting software versions:
libxine: 1.1.16
phonon: svn revision 906930 (4.1.87) /trunk/kdesupport/phonon
kde: 4.1.87 packages from opensuse buildservice

kernel 2.6.27.7
powertop 1.10


I noticed this is related to recently worked on knotify4 bugs, but it didn't seem to fix it for me, maybe I got the wrong svn branch?

Thanks for your time!
