I'm not sure about your microphone problem, but I can say for
certain that the card is indeed capable of full-duplex operation.
Unfortunately, if it's recording at 16-bits, it can only play at
8-bits (or vice-versa).  This is usually adequate for monitoring
while recording, though not for mixing the played signal with
the new for special effects like voice doubling.

The ViBRA 16, if it is the CT417x series (also used in
WavEffects models) is capable of full-duplex with 16-bits
in both directions, even though it only uses 8-bit DMA
channels... it sends 16-bit data as 2 separate bytes.
This consumes some extra bus bandwidth, but it's
usually OK.

So if your drivers don't allow full-duplex operation with
either of these boards, it's probably time for new drivers.
Unfortunately, I can't help you there... I only write drivers
for my DAQARTA system, not general-purpose drivers.
Maybe you can find something at Creative's site:

Hope this helps.
