 * 	1. Codec domain - VREF, VMID

 *     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

 *  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.
