>Description:
Since 1.6Z* (IIRC) everyonce in while my audio hardware dies during playing.
This means every audio application will hang in either "aud_wr" or "aud_rd"
and if I kill -9 the process it takes several seconds until the process
is finally removed. I've noticed that the audio hardware won't generate
any IRQs after that but I don't know whether that's a source or a symptom
of the problem. I know of no other way than a reboot to make the hardware
working again.

>How-To-Repeat:
I have no idea how to reproduce this problem at will. It happens after minutes,
hours or days. Though, I think it only happens at the end of a file/song/track.
I've seen this when using mplayer and ogg123.
