| 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). |
