- *    o Changes power status of internal codec blocks depending on the

- *      DACs/ADCs.
- *    o Platform power domain - can support external components i.e. amps and
- *      mic/headphone insertion events.
- *    o Automatic Mic Bias support
- *    o Jack insertion power event initiation - e.g. hp insertion will enable
- *      sinks, dacs, etc
- *    o Delayed power down of audio subsystem to reduce pops between a quick
- *      device reopen.
