I've realized that the microphone is started way before all daemons
are started. In other words the mic is probed during the device
discovery sequence (when the characters are green on the console).

The built in mic is mapped by mixerctl as inputs.record2.

Is there any way to map this entry to a driver, and if possible to
manipulate it.

My dmesg is here:
