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. | |
