After updating my Framework Laptop 13 (AMD Ryzen AI 300 series) to a recent (unstable) revision of NixOS, the built-in microphone stopped working. I found a workaround and wrote about it in this nixos-hardware issue. I am opening this so that people with the same issue might come across it.
Not a framework user, but I also am the owner of a Legion 5 laptop with Ryzen AI 7 350 CPU, and have NixOS on it. My microphone is there but it doesn’t register any sound. It shows up as picking up something vary loud (going to max volume) all the time, but on playback, there’s silence.
Can confirm the fix is working for me, thanks!
I can also confirm that this works for my fedora 42 fw ryzen AI 9 370 system.
I’m showing this same issue on Fedora 42 Kinoite. So far haven’t been able to solve, but perhaps I’m not editing the right configs.
EDIT: /etc/wireplumber/wireplumber.conf.d/alsa-config.conf with the fix above worked.
