Talk:PipeWire

      - The option definition `services.pipewire.config' in `/etc/nixos/configuration.nix' no longer has any effect; please remove it.
      Overriding default Pipewire configuration through NixOS options never worked correctly and is no longer supported.
      Please create drop-in files in /etc/pipewire/pipewire.conf.d/ to make the desired setting changes instead.

Wireplumber configuration example discrepancies

The configuration examples for wireplumber have confusing differences compared to Wireplumber Bluetooth configuration documentation. For example this one on the wiki page:

environment.etc = {
	"wireplumber/bluetooth.lua.d/51-bluez-config.lua".text = ''
		bluez_monitor.properties = {
			["bluez5.enable-sbc-xq"] = true,
			["bluez5.enable-msbc"] = true,
			["bluez5.enable-hw-volume"] = true,
			["bluez5.headset-roles"] = "[ hsp_hs hsp_ag hfp_hf hfp_ag ]"
		}
	'';
};

The differences are:

1. Instead of bluez_monitor.properties,
   Wireplumber documentation uses monitor.bluez.properties.
2. Instead of ["bracketed.and.quoted.property.names"],
   Wireplumber documentation uses plain.property.names.
3. Instead of ending each property line with a comma (... = true,),
   Wireplumber documentation omits the comma (... = true).

Ah, Pipewire configuration format changed between versions 0.4 and 0.5, and NixOS 23.11 has:

$ wireplumber --version
wireplumber
Compiled with libwireplumber 0.4.17
Linked with libwireplumber 0.4.17
$ ls -l `which wpctl`
lrwxrwxrwx 1 root root 72  1. 1.  1970 /run/current-system/sw/bin/wpctl -> /nix/store/a13fw6xw8fmpf39blrp86w6r7nkfrim5-wireplumber-0.4.17/bin/wpctl

(Although I don't yet understand why I still get:)

$ nix derivation show 'nixpkgs#wireplumber'

  "/nix/store/cawvgg6wk42xmhpg2dm0ax9hxbxfdsfm-wireplumber-0.5.2.drv": {
