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