|

* Usually controlled at codec probe/remove, although can be set
|

* at stream time if power is not needed for sidetone, etc.
|
||||
* 2. Platform/Machine domain - physically connected inputs and outputs
|
||||
* Is platform/machine and user action specific, is set in the machine
|
||||
* driver and by userspace e.g when HP are inserted
|
||||
* 3. Path domain - Internal codec path mixers
|
||||
* Are automatically set when mixer and mux settings are
|
||||
* changed by the user.
|
||||
* 4. Stream domain - DAC's and ADC's.
|
||||
* Enabled when stream playback/capture is started.
