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