Although I intend to make this driver fairly complete, I have not done the
following:

CONFIGURATION  It would be great if you didn't have to modify include/sound.h
to change the dma, irq, and base address, though I did use the factory defaults
which is probably what most people use in real dos (save them configuring their
games...)

OTHER BOARDS  While no one will be left out by the included dsp capabilities,
there is now support for GUS or OPL-3.  I have an OPL-3, so I'll probably
write the code whenever I get around to finding docs.  However, I have no
intention of writing code for GUS

MIXERS  The current mixer code is limited to what SB Pro provides, which is
not much.

COMMANDS  It would be real nice if DOSEMU included sound playback + record
utilities and a mixer...

I NEED YOUR HELP!
I don't intend to do any of this except the OPL-3 support.  If you want it
supported, why don't you invest a little of your time and work on one of the
things listed here.
