+
+          After the snd-ac97-codec driver module has been loaded,

-  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.
