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

86 * Most of the mixer entries work in backwards. Setting the polarity field
87 * makes them to work correctly.
89 * The channel numbering used by individual soundcards is not fixed. Some
90 * cards have assigned different meanings for the AUX1, AUX2 and LINE inputs.
91 * The current version doesn't try to compensate this.
