NixOS Audio IO not working

Help
1

Hello, I recently got a new laptop, the Lambda/Razer tensorbook, which ships with ubuntu. I installed NixOS onto it with no issues, and I’m using hyprland as my compositor. Audio works, but I can’t change the volume and when I select a mic to use for Discord or Slack in my browser (Brave) or in OBS, the input isn’t showing up. Same with output in those cases. The audio for the desktop works though, eg notifications and such.

Is there something I’m missing in my config?

  sound.enable = true;
  hardware.pulseaudio.enable = false;
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;
    audio.enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    jack.enable = true;
    wireplumber.enable = true;
  };

CPU: 12th Gen Intel i7-12800H (20) @ 4.700GHz
GPU: NVIDIA Geforce RTX 3070 Ti Laptop GPU 
GPU: Intel Alder Lake-P

In the apps mentioned, it seems the only available input sources are from the Alder Lake. Not sure if that has something to do with it. Also, plugging in headphones that have a mic works, but without it doesn’t.

hey did you fix this issue yet? i have this exact error on my hyprland laptop.

The problem for me was the laptop type, it’s a razer laptop so I had to add some special audio topology file to be loaded as an extra kernel package. Here’s my dotfiles for that system: dotfiles/nixos/configuration.nix at 5f6077c2987f9c2ad3a1efd07b26a2d85465d5e0 · eureka-cpu/dotfiles · GitHub
