How to quickly fix the sound from the headphone jack and microphones in FreeBSD with the X1 Carbon 6th gen (same process applies to many other laptop models).
It's just a matter of finding the appropriate nid and correcting their as numbers. I also forgot to mention that I changed the seq numbers too which you can see in my /boot/device.hints file.
In summary:
Press '6' at boot time.
Turn verbose booting on.
Boot.
Run dmesg and pipe/grep/more to find hda* entries:
Find appropriate nids and adjust their as and seq numbers accordingly.
From what I understand, the seq number is basically like a priority indicator with 15 being the lowest. So you want your internal devices to have a higher number (0 = internal, 15 = jack).
Also correcting a mistake made in my last video about the X1 Carbon 6th gen's Intel 8265 wireless device - works perfectly (I was wrong and my router sucks).
