ALSA: hda - Set internal mic as default input source on Dell XPS 13 9333
If the laptop is powered on with a jack plugged in, independently on what
is plugged, the jack is treated as a microphone jack.
Initialize the capture source so that by default jacks are treated as
headphones jacks. This will also prevent pop noises on boot in case
headphones are plugged in since setting/unsetting mic-in as input source
causes a pop noise.
