The number of interrupts goes up a lot, just for starting the song
player. I guess it does a open() on the sound device. These interrupts
numbers are just because of starting amarok, i don't even play a song in
this software. So here a two options:
1.) fix amarok to open the sound device when it's needed
2.) fix the kernel sound card driver to setup everthing, when an
application want to put data on the device
what do you think about this?
