| 362 | * On almost all devices, only the tuner input is used. |
| 363 | * |
| 364 | * However, on most devices, an auxiliary AC97 codec device is used, |
| 365 | * usually connected to the em28xx tuner input (except for |

| 367 | * |
| 368 | * The AC97 device typically have several different inputs and outputs. |
| 369 | * The exact number and description depends on their model. |
| 370 | * |
| 371 | * It is possible to AC97 to mixer more than one different entries at the |
| 372 | * same time, via the alsa mux. |
