* The AD1848 codec has generic input lines called Line, Aux1 and Aux2.
* Sound card manufacturers have connected actual inputs (CD, synth, line,
* etc) to these inputs in different order. Therefore it's difficult
* to assign mixer channels 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).
