Microphone Not Working Dual Codec ALC1220

Version, Distribution, Desktop Environment:

  • Arch Linux 5.12.14-arch1-1
  • KDE Plasma 5.22.2
  • Pipewire 0.3.31

Description of Problem: Microphone input from Realtek ALC1220 sound card with Dual Codecs not producing any sound.

Steps to Reproduce:

  1. arecord -vvv --format=dat --device=plughw:0,4 /dev/null

Actual Results: No sound recorded from ALC1220 microphone jacks.

Expected Results: Sound recorded from ALC1220 microphone inputs.

Additional Info: I have had issues with this sound card before. It is an ALC1220 Dual Codec Sound card. You can see previous troubleshooting here: https://bbs.archlinux.org/viewtopic.php?id=262558. It ended up being a kernel issue before. But my upgrade to Pipewire has broken it. Two other microphones on my system are working properly. I have confirmed that it is not a hardware issue, running other distros without Pipewire work fine.
