Speaker / Mic on different sound devices. Need to modify 'Pins'?

F

Hello,

One of the last things I need configured on my notebook is the microphone. I have two sound devices, the one that has the speakers and the other which has the mic. If I'm using Audacity to record the audio, I'm able to manually specify it no problem, but this is an issue with Jitsi through Chrome or Firefox as that flexibility is missing.

I believe I have to adjust the 'pins', but after a year of on and off trying to tinker with the audio settings, I'm seeking some guidance as to what I need to modify.

Code: 
$ cat /dev/sndstat
Installed devices:
pcm0: <IDT 92HD81B1X (Analog 2.0+HP/2.0)> (play/rec) default <- Speakers / Headphone
pcm1: <IDT 92HD81B1X (Analog Mic)> (rec) <- Mic that I want to record my audio
No devices installed from userspace.

Code: 
mixer for pcm0
# mixer
Mixer vol      is currently set to 100:100
Mixer pcm      is currently set to 100:100
Mixer speaker  is currently set to 100:100
Mixer mic      is currently set to 100:100
Mixer mix      is currently set to 100:100
Mixer rec      is currently set to 100:100
Mixer ogain    is currently set to 100:100
Recording source: mic

Code: 
mixer for pcm1
# mixer
Mixer rec      is currently set to 100:100
Mixer monitor  is currently set to 100:100
Recording source: monitor

Code: 
sysctl dev.hdac.0.pindump=1

I know the information above *should* be enough to modify the boot device hints, but I'm still at a loss as to how to parse the above dump and then structure it to be interpreted at boot.
I'll even happily take reading recommendations. I'm just tired of spinning my wheels on this as I feel like it's far simpler than I'm making it out to be!
 
Not a direct answer. Sound recording in front jack of my PC sits on another PCI bus than the one on the rear jack. And I could only make the front jack working.
man snd_hda,

$sysctl -a | grep pcm | grep rec
 
Code: 
# sysctl -a | grep pcm | grep rec
dev.pcm.1.rec.vchanformat: s16le:2.0
dev.pcm.1.rec.vchanrate: 48000
dev.pcm.1.rec.vchanmode: fixed

I was able to get it working by placing the following in my /boot/devices.hints:

Code: 
hint.hdac.0.cad0.nid12.config="as=0 seq=0       device=Mic"
hint.hdac.0.cad0.nid17.config="as=2 seq=15      device=Mic"

Unfortunately, I don't have a firm grasp as to *why* it worked. The first entry I believe basically 'throws away' the mic jack (at least that's my assumption). The second entry I set the same 'as' as the first entry with the built in mic, but what significance does the 'seq' have? I set it to 15 because 0 failed.
