OS/Distibution: NixOS 25.11, but likely affects all distributions, last updated 2026-01-22
Which kernel are you using: 6.18.6
Which BIOS version are you using: 0.0.3.5
Framework 13 Ryzen AI 300 (I suspect FW 16 Ryzen AI 300 is also affected).
Here is a more detailed discussion including the ALSA author and some details on ACPI tables: Framework Laptop 13 microphone stopped working · Issue #1603 · NixOS/nixos-hardware · GitHub
I didn’t find any other way to properly reach out to the framework team, so hopefully this works.
