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.

/*
|
|
* The AD1848 codec has generic input lines called Line, Aux1 and Aux2.
|
|
* Soundcard manufacturers have connected actual inputs (CD, synth, line,
|
|
* etc) to these inputs in different order. Therefore it's difficult
|
|
* to assign mixer channels to to these inputs correctly. The following
|
|
* contains two alternative mappings. The first one is for GUS MAX and
|
|
* the second is just a generic one (line1, line2 and line3).
|
|
* (Actually this is not a mapping but rather some kind of interleaving
|
|
* solution).
