Audio Issues on Acer Chromebook 314 (CBOA314-1H-C32M)

Hey folks,

I’m running NixOS on a Chromebook (Jasperlake, rt5650).
On Arch Linux I can get audio working using alsa-ucm-conf-cros, but on NixOS it’s been quite a pain.

Has anyone managed to get this working on NixOS?
Maybe there’s already a module or a clean way to integrate this UCM config into the system?

Any pointers appreciated!
