Windows Users:
The 'full duplex' feature of some audio boards will probably be the main
dividing line between what we recommend and don't recommend for use with
CU-SeeMe. If anyone knows of other sound cards that can play audio while
recording (not including just echoing what you're recording) please let us

The pro audio spectrum 16 and the Gravis Ultrasound boards are full duplex.
