Comment 3 for bug 277243

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
