Windows Users:
This is certainly a good question; I believe that since the sound blaster
was such a clear market leader for so long they kind of created a standard
which all later sound cards followed. I believe that all the sound cards
in the market now are compatible with or supersets of the sound blaster card
and I haven't heard from alpha testers of any cards that won't work with
CU-SeeMe (we don't use any of the optional features like variable rate
playback or even stereo). But, by all means let us know if the upcoming
0.65 beta does not work with your existing sound card in a couple of weeks.

Do those three you mentioned work with CU-SeeMe?
