>Description:
When using cat to play .au files to the /dev/audio interface with the
bsd_audio and soundblaster drivers configured, the cat process will
occationally hang waiting on "audio". It is not interruptable. To
further confuse things, if I try to use the floppy device when this
happens, it gets a series of errors on the console, but appears to
work. And the "cat" process is waked and the sounds get played.

Here is the 'ps axl' state of the "cat":
10066 25319 25309   4  10  0    60   16 audio  I    ??    0:00.08 cat src/audio/sounds/BigBen.au

Here are the messages from the console:
fd0: read failed st0 40<abnrml> st1 10<data_overrun> st2 0 cyl 0 head 0 sec 6
blkno 4 skip 0 cylin 0 status 40

do
	cat BigBen.au > /dev/audio
until sleeps...
