I suggest you talk to Eric Pouech <[EMAIL PROTECTED]>. He was active on the patch list yesterday so I suppose he will see this and reply. In the mean time I can tell you that the PCM support is in wine/dlls/mcacm and ADPCM support should be there as well. There is a file pcmconverter.c that implements PCM support so I suppose that there should be a adpcmconverter.c file to plug in the ADPCM support. There will probably need to be a few changes in other files as well. Anyway Eric understands this better than I do. Let's wait and see what he has to say.
