I believe Cubase (I think) used to let you do that for multitrack
recording...so I think it is possible. You may want to look into using
a souncard with 7.1 outputs or something though.

Yes - I do this on a regular basis.  You do have to make sure that the
application(s) you want to use has the ability to select the particular
card you want.

The first machine I set up like this is running XP Home Edition: the mobo
audio is being used by Audioools  <http://www.unrelatedinventions.com/>
while an Audigy 1 card is being used by BMS
<http://nch.com.au/bms/index.html>.  Both applications are running at the
same time doing completely unrelated tasks with no problems on a Duron 2000.

FWIW: Audiotools is a seriously cool and very inexpensive direct-to-disk
audio recorder / editor.  Its very much worth checking out.  The author,
Andrew Fish, is very supportive and very approachable.  He is also known
for being one of the developers of a professional distributed audio control
system known as Sound Web (from BSS).  There is a pretty good chance that
the PA system at any large concert you might have attended recently was
controlled by Sound Web.

BMS is short for Business Music System - this package plays music and
intersperses pre-recorded announcements at specified times.  While usable,
the package seems incomplete and their tech support is a complete waste
time and money (you have to pre-pay for tech support).  I'm working with
Andrew Fish (mentioned above) to have an Audiotools plug-in developed to
perform a similar function as BMS.  This is one case where a really bad
attitude is going to cost that company any chance of future sales with me.

You can put as many soundcards as you dare into an XP machine. 3 is the
most I have seen so far (one onboard + 2 PCI cards). But the machine ran
much better under linux ... with the three soundcards ;-)

Windows has APIs that let you directly control the sound card output,
providing samples to be blasted out.

So....

A software program can mix together as many simultaneous sound sources as
you want, up to the CPU capability of your machine and then output the
result in real time to your single sound card. Such a program would have to
be written (or found).

Game programs do this all the time (background music, bullet shots,
explosions, grunts when you're hit, etc, etc, etc).

You may find that you can coerce the game development package 'GameMaker'
(which is freeware) to do what you want.

Don't you eventually run into contention for DMA channels?  Or do PCI
soundcards not use the same DMA resources?  Or do they share?

I don't know but I have seen three work at the same time. One of them
was doing 5.1 sound for dvd the other two did something else. One of the
cards was being used full duplex.

I'm not sure what DMA does on modern PCI cards which have onboard
buffers, besides stealing cycles from the ram subsystem.
