Use mic from headphone jack on freebsd laptop?

[Johannes Lundberg]

Hi

On my Dell laptop the output audio switches to the headphones
automatically when plugged in, however, the same does not seem to be
true for the mic. Is there any configuration magic that can be done to
use the headphone mic instead of the internal one?

Here's pin config:

hdaa1: NumGPIO=0 NumGPO=0 NumGPI=0 GPIWake=0 GPIUnsol=0

And in /boot/loader.conf I have this (don't remember why I put it there
or if I need it - it might have been copied over from previous laptop)

hint.hdaa.0.nid33.config="as=1 seq=15 device=Headphones"

I'm assuming here that the headphone jack supports mic - it's a 2018
laptop after all.
