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:
- 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.
