| 12 | Lot of voodoo here. Even the data sheet doesn't help to |
| 13 | understand what is going on here, the documentation for the audio |
| 14 | part of the cx2388x chip is *very* bad. |
| 15 | |
| 16 | Some of this comes from party done linux driver sources I got from |
| 17 | [undocumented]. |
| 18 | |
| 19 | Some comes from the dscaler sources, one of the dscaler driver guy works |
| 20 | for Conexant ... |
