I doubt that this bug is a duplicate of bug #73744 since i clearly
said, that it doesn't matter if i use alsa or pulseaudio. I know about
bug #73744 and experienced the difference in hardy myself, but in hardy
i could switch to alsa and the high load was gone... Also in bug #73744
the process pulseaudio itself causes high load, here the application
playing sound...
But the latest updates were helpfull. The load while playing music
droped normal values
