  Note that the AWE64 is not a 'true' full-duplex card, just like
the Vibra one.  Full-duplex is simulated in software, with a number of
nasty side-effects.

  Why you can't get the recording to work I'm not otherwise sure.

hi,
i had the same problem on a _very_ new soundcard and found a reason and a
solution (on my machine).
Reason:  all types of mikes are equal - but some are more equal!
make a 'flying' connection from the mike-join to a second join that is plugged
to the soundcard.
try all possible connections especially change the stero-signals (NOT THE
GROUND) or try only one of the channels.

Seems to me that the standards of mikes changed during the last years. I had
three mikes - no one works well. but with the information i'v got with the
tests by 'flying wires and clamps' a was able to buy a new one that matches!
Now all runs well!

Hope I could help you. :-)

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:
   www.soundblaster.com

Hope this helps.

Actually, the "duplex" term dates from the days of analog telephony,
and "full duplex" only indicates that  "send" and "receive" take place
at the same time, as opposed to "half duplex" where only one direction
is possible at a time.  It has nothing to do with bits of resolution,
but it's true that there is a reasonable expectation of symmetry...
I guess people would have been pretty upset if the old analog
telephone conversations had more distortion in one direction
than the other!  So while Creative's use of "full duplex" is fully
proper by the old hair-splitting definition, it's really a marketing
gimmick to cover a product weakness.

hmm..don't want to split hairs but its not *proper* full duplex is it..if
you record at 16 bit, you can only monitor at 8 bit (telephone line) which
is a bit crappy..a neat solution is to install 2 awe 64cards (they're only
20-odd quid)..one for record and one for playback..creative have always been
a bit naughty with their advertising..like for the new(ish) sblive which
perports to spdif i/o..it turns out to be not *proper* spdif..
