  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 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).
