There are websites 'out there' which tell you how to program a sound
blaster card via basic with inp and out.  The sound blaster interface is
well documented, and many 16 bit sound cards were made that support it
without a driver.  (many were also made that had to have a DOS driver
emulate it - try and see)

I suspect that if you start off with a real sound blaster, especially if
you can get an older one with jumper settings for I/O and IRQ, then
you'll have it buzzing merrily along in no time.

Hopefully this will help you find what you're looking for.  If you want
to use a card other than a soundblaster, you can try checking out the
linux support for that card and then look at the source code for it.
Probably won't be as easy to get started, but it's a start.
