| 22 | ALSA SOC usually puts the device in standby mode when it's not used |
| 23 | for sometime. If you unset is_powered_on_standby the driver will |
| 24 | turn off the ADC/DAC when this callback is invoked and turn it back |
| 25 | on when needed. Unfortunately this will result in a very light bump |
| 26 | (it can be audible only with good earphones). If this bothers you |
| 27 | set is_powered_on_standby, you will have slightly higher power |
| 28 | consumption. Please note that sending the L3 command for ADC is |
| 29 | enough to make the bump, so it doesn't make difference if you |
| 30 | completely take off power from the codec. |
