I have a Ultra1 with CS4231A audio cipset and all the mixers
are not working.
"cat /dev/sndstat " is not working:
cat: /dev/sndstat: Device not configured
"cat foo.wav > /dev/dsp" works
/dev/sndstat is not supported by the sparc audio drivers.
aumix should work in non-interactive mode; interactive is
still broken. It's a problem with the kernel drivers; we're
looking at it, but it may not be fixed for a while.
