Amancio. There is some SoundSource support here that is primitive and probably doesn't work, but I'll let the two submitters let me know how my integration of that was since I don't have this card to test. I've only tested this on my GUS MAX since it's all I have. This all probably needs to be re-done anyway since we're widely variant from the original VOXWARE source in the current layout.
