I am assuming that this is not a problem with the x86 port, since the sound
support for UNIX is geared towards Linux on x86, and I have yet to read
such a complaint on the Atari800 mailing list..

That's what I am thinking, but as I said, I just haven't had the time to
delve much into the PPC sound stuff in the kernel... so I was just asking
for some help.. I may try again this weekend if I don't have to work, but
then my girlfriend would probably hate me even more :)  I'm already
spending a good 12-16 hours/day at work... (some advice for everyone:
never accept a job at a small company that's been around for 15 years, has
10 software products, and no current developers.. all of this ==
nightmares, headaches, lack of sleep, etc :)
