| 33 | * 2. Platform/Machine domain - physically connected inputs and outputs |
| 34 | * Is platform/machine and user action specific, is set in the machine |
| 35 | * driver and by userspace e.g when HP are inserted |
| 36 | * 3. Path domain - Internal codec path mixers |
| 37 | * Are automatically set when mixer and mux settings are |
