Now that I'm running a -current system, I've noticed that I have a
character device called asc0 which the MAKEDEV script identifies as
being associated with the Apple Sound Chip.  I've tried catting text to
the device in the hopes that some noise would come out of my speaker, but
nothing happens.  Can anyone tell me if this thing is actually function
-al or not, and if so, how can it be used?  Thanks.
