Firstly, get and read the FAQ.

When you've done that, you have two choices:

1) Get a DJGPP-specific library
2) Hack the code you already have

As for (1), there's sb05_dj2, which has routines to play wav files and mod
files, I think, and there's Allegro, which does a whole lot more.

Re (2), briefly, you need to:

* Sort out the ISR so that it works in protected mode (RTFAQ)
* Allocate the buffer in the low memory area (RTFAQ)
* Put the data into this buffer
* Set up and initiate the DMA transfer, passing it the address of this buffer

These aren't serious modifications, and the FAQ has a lot of information
on porting Watcom/Borland/etc programs to DJGPP.
