I install NixOS 23.05 at my thinkpad E330, but found that my mic record distorted sound (it record something but with defects), Then I try NixOS on my thinkpad x220 and found same defect. For X220 after some reserch I solve it with GitHub - NixOS/nixos-hardware: A collection of NixOS modules covering hardware quirks. :
I add this:
imports = [ <nixos-hardware/lenovo/thinkpad/x220> ./hardware-configuration.nix ];
But there is no config for thinkpad E330, I try x220 and e470 but this take no effect.
Please help to fix this for thinkpad e330.
