-#define POWER_OFF_ON_STANDBY 1
-/*
- ALSA SOC usually puts the device in standby mode when it's not used
- for sometime. If you define POWER_OFF_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
- just comment this line, 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.
