NetBSD-current/i386 does support the Gravis UltraSound (which, by the way, does not support the SoundBlaster interfaces in hardware--they do it on DOS with software drivers), and you can send 44.1kHz stereo 16-bit data out it, although sometimes the audio gets a bit "fuzzy" for some reason I've not debugged yet. -- John Kohl <jtk@tiac.net> or <jtk@kolvir.arlington.ma.us>
