System76 pang12 audio support

Enables internal mic, but I'll need to find a quirk for the combo jack to show a prompt

This is very close, but I can still break it with a specific sequence of events: #220

Since this sequence of events seems like a pretty unlikely one, and the overall impact of it happening is very low (user just has to unplug and re-plug the headphones, or change back to the built-in mic in sound settings), I am approving after opening #220 to track that last little remnant of the combo jack bug.

Hi, is there any plans to send it to upstream? I'm using Arch Linux (6.2.9-arch1) on pang12 model and my audio (mic) doesn't work. It does seem to work when I tried a live boot of PopOS. Fix on Linux Kernel would be nice.

@jackpot51 agreeing with above, is this being pushed to upstream? Mic is confirmed not to work on vanilla kernel.

It was upstreamed. It takes time for changes like that to propagate back downstream.

Specifically, the DMI entry has been upstreamed. It is currently in the for-next branch: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/commit/?id=7b9891ad25246b18b5ccc19518da7abc7763aa0a

I did not submit the duplicated codec entry.

@WingofaGriffin: have you tested the new kernel? In 6.3.4-arch1-1 (Arch Linux) the Mic is shown in the pulseaudio finally, but it still doesn't take any inputs. No recording activity.

[WingofaGriffin]

I indeed still do not seem to be getting any inputs or recording activity.

[Atreyagaurav]

That makes sense, when I looked further the Mic that's shown seems to be for headphone jack (as it says unplugged) not internal mic.

Update, the mic can be seen from the Pulseaudio control now:

There is no "Base" like in others, but it seems to be working.

EDIT: I'm on 6.3.8-arch1-1, it could have been fixed earlier.
