Csound writes to standard MME WAVE drivers. If a soundcard 'device'
supports multiple channels (e.g Sonorus STUDI/O, Creamware Pulsar,
Frontier WaveCenter, etc), Csound can drive it. The code does not write
to multiple devices (they ~can~ be synced, but I don't think it should
be relied upon). A multi-channel driver is the way to go. At some point,
I (or someone) will add support for WAVE-EX to Csound for use under
Windows2000; this can downmix and dither (if necessary) a multi-channel
stream according to the capacity of the card. Anyone lucky enough to
have a multi-channel card under Linux (basically, just the Sonorus
STUDI/O at present, I think) can also output multi-channel audio.

Csound can write several file formats - AIFF, WAVE (32bit float and
16bit), and others. IIRC, data is just cast from floats to 16bit for
audio rendering. There is no difficulty in principle in writing 24bit
data to a card that can support it.
