/*
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).
