Microsoft DirectX doesn't support audio IN yet. So it is possible to use
audio IN together with audio OUT only with the old MME windows driver.
You must have two audio cards or a full-duplex card. Notice that the
Soundblaster 16 audio IN is automatically reduced  to  8-bit resolution
when using full-duplex. I don't know if this restriction is present also
for the AWE64.
To use both audio in and out with midi, you must call my version of
Csound with the following flags:

csound.exe   -+K  -+q   -+e   -+p12  -b800  -i     pluto.orc pluto.sco

It is suggested to use  sr=32000 or sr=40000 when using old MME drivers.

Good luck

DX5 does input through DirectSoundCapture, but it's implemented as an
emulation layer on top of waveIn*().
