>Description:

typically after few hours (maybe tens of minutes, i've not checked it
precisely yet and it doesn't seem to be the same time interval every time),
auich(4) driver in my laptop hangs and refuses to play for several minutes or
at all.  application using sound at the time of hang stops in aud_dr.  e.g.
mplayer is able to recover from this state but mpg123 is not (maybe not
always).  warm reboot doesn't help, only power cycle.

hangs always announce themselves with a very short white noise sound, then
silence follows.  attempt to play some file with e.g. mpg123 results in the
same effect--white noise && silence, sometimes the noise repeats.
