| ALSA SOC usually puts the device in standby mode when it's not used |
| for sometime. If you unset is_powered_on_standby the driver will |
| turn off the ADC/DAC when this callback is invoked and turn it back |
| on when needed. Unfortunately this will result in a very light bump |
| (it can be audible only with good earphones). If this bothers you |
| set is_powered_on_standby, you will have slightly higher power |
| consumption. Please note that sending the L3 command for ADC is |
| enough to make the bump, so it doesn't make difference if you |
| completely take off power from the codec. |
