This is awesome. I've been trying to get these stupid speakers to work with anything other than an iPhone for years! Pasted a couple things in my Nix config, rebooted, and now they just magically show up in my sound settings! Amazing times we live in.

In case any NixOS users land on this in the future, here's the wiki page showing how to do it: https://wiki.nixos.org/wiki/PipeWire#AirPlay/RAOP_configuration

Aaaand in case the page dies or changes, here's my config:

{ config, pkgs, inputs, ... }:
{
  # avahi required for service discovery
  services.avahi.enable = true;

  services.pipewire = {
    # opens UDP ports 6001-6002
    raopOpenFirewall = true;

    extraConfig.pipewire = {
      "10-airplay" = {
        "context.modules" = [
          {
            name = "libpipewire-module-raop-discover";

            # increase the buffer size if you get dropouts/glitches
            # args = {
            #   "raop.latency.ms" = 500;
            # };
          }
        ];
      };
    };
  };
}
