31/*
32 ALSA SOC usually puts the device in standby mode when it's not used
33 for sometime. If you define POWER_OFF_ON_STANDBY the driver will
34 turn off the ADC/DAC when this callback is invoked and turn it back
35 on when needed. Unfortunately this will result in a very light bump
36 (it can be audible only with good earphones). If this bothers you
37 just comment this line, you will have slightly higher power
38 consumption . Please note that sending the L3 command for ADC is
39 enough to make the bump, so it doesn't make difference if you
40 completely take off power from the codec.
