I have recently installed FreeBSD 2.1.0-release on my system, and I have
encountered this strange problem.
I have a Gravis Ultrasound card with 1 MB of ram. I recompiled the kernel
with gus0 enabled and ran 'sh MAKEDEV gusmax' (I don't have a GUS Max, but
it's the closest one I can find.) dmesg showed the kernel found the GUS
properly (see dmesg output at the end of message).
I can play au files file by catting the file to /dev/audio, but if I try
to play the au file again, the system hangs. I had the same problem in
Linux, but it's fine if I flush out the disk buffer or the sound card
buffer first, by playing other sound files. I suspect this is a driver
problem.
Any help will be appreciated.
This is my /etc/sndstat
