Front Panel Audio Issues - ALC4080

Help
1

Hello!

I recently built a new computer and I am having difficultly debugging an audio issue. The audio on the back panel works, but front panel audio does not. I have tested front panel audio in a Windows VM and it works fine there.

The motherboard I am using is a MSI X870E Tomahawk which has a Realtek ALC4080 Codec.

I am currently on NixOS unstable and Linux kernel version 6.12.32.

Below is an excerpt of my configuration with all of the settings I have for sound.

{
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    };
}
