Pipewire audio switch

Help

Hey the new nixos wiki PipeWire - NixOS Wiki is missing a information about Pipewire on NixOS how to enable pipewire audio switch automatically on NixOS when i plug a headset ?

Did you figure out how to set this up in PipeWire in general?

I’m having the same issue here.
When I plug/unplug my headphones, it does not auto switch the output device.

One less than ideal solution is to install pavucontrol > open the GUI app > plug your headphones > open the Output Devices tab > enable the checkmark option Set as fallback

My config is the default one, provided from PipeWire

{
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    jack.enable = true;
    audio.enable = true;
  };
}

This isn’t really a NixOS question as this is just about regular upstream pipewire/wireplumber functionality.

I don’t know that this is how it works but for me it remembers that I have set a device as fall-back and switches back to it when I plug it in again.

Should you be using impermanence, ensure you’ve allowed such wireplumber state to persist as it couldn’t possibly do this without storing that state.
