well, to make things a bit harder, (at least) two ADPCM exist:
- IMA and MS
basic algorithm are quite the same, coeff tables differ a bit.

I did start a while ago an IMA ADPCM driver for wine
it's not finished yet (basically, didn't find time to look at in depth
docs for some details, like coding/decoding of stereo vs mono)
it's far from being finished and tested, but the framework (wine
integration, 
driver infrastructure) is in place, there's just some need to
concentrate
on codec code

so, if you're ready to go for it, I can send you the code and give you
the directions to end up the job

A+
