Are you asking about 6 channels in general, or 6 channels specifically
from a DVD source?
The Dolby Digital (aka AC-3) encoding found on most DVD-Video discs
does not necessarily imply all 6 channels. It's just an encoding
format, which can be anything from 1 channel Mono to the full 5.1
It would be Really Cool to be able to pop a DVD into a NetBSD box with
a DVD-ROM drive and get 5.1 Dolby Digital out of USB speakers. But
assuming everything else were in place, having a software DD decoder
would be the kicker. Somehow I doubt that's feasible. I don't know
of any sound cards offhand that do DD either, but we can dream... :)
