output from lsbusb -v

"ID 0414:a00d Giga-Byte Technology Co., Ltd USB Audio" is the built in motherboard analog jacks on some gigabyte b(450/550) motherboards.

The symptom is the headphones create output, but the input (both microphone and line-in) do not work in most applications. This issue occurs in both pulseaudio and pipewire.

Trying to solve the issue in wireplumber was [redirected](https://gitlab.freedesktop.org/pipewire/wireplumber/-/issues/268#note_1385274) to ALSA.

Disableing using ACP via wireplumber seemed to almost fix the mic-in issue, but completely broke headphones. 

Attached is the output of lsusb -v

Might be related to https://bugzilla.kernel.org/show_bug.cgi?id=206873
Comment 2 Brock Szuszczewicz 2022-05-17 00:10:32 UTC 
Probably very similar to https://lore.kernel.org/all/20200408140449.22319-1-tiwai@suse.de/
From my naive modifications to that, I have not gotten mic/line-in to work though.
Comment 3 Brock Szuszczewicz 2022-05-19 00:26:36 UTC 
Probably a dupe of https://bugzilla.kernel.org/show_bug.cgi?id=206543, but leaving this open as the thread there has been derailed with off topic issues

correct alsa info

The last attached `alsa-info` was from a modified kernel, this is from a clean install.

Thi kernel patch is provided by Takashi Iwai
Thank you so much for the help!

To completely fix the mic another patch is required in userspace here:

The patch was merged to sound git tree, likely included in 5.19-rc1 (via the second pull request).
