I noticed this behaviour when trying to debug full duplex mode on the  
dbri driver - I had one process play something, then had another read  
from /dev/ausio - as soon as the 2nd one terminated the playing  
process hung because the audio device was shut down. Tracked it down  
to audio.c but didn't get around to dig any deeper yet ( not that I'm  
familiar with the MI audio code )

have fun
Michael
