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