hmm maybe I set the paths in ardour?

i just spun up a fresh NixOS 23.05 stable Gnome VM using the GUI ISO and the GUI installer. I then modified the /etc/nixos/configuration.nix to be:

 users.users.lol = {
    isNormalUser = true;
    description = "lol";
    extraGroups = [ "networkmanager" "wheel" ];
    packages = with pkgs; [
      firefox
    #  thunderbird
# ADDED BY ME START
ardour
lsp-plugins
x42-plugins
carla
# ADDED BY ME END
    ];
  };
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    # If you want to use JACK applications, uncomment this
    jack.enable = true;

    # use the example session manager (no others are packaged yet so this is enabled by default,
    # no need to redefine it in your config for now)
    #media-session.enable = true;
  };

nixos-rebuild boot --upgrade. Reboot.
Result. Ardour cant find the plugins. Either the approach is flawed or there is a bug here.

in my personal config, I have set:

{
  environment.pathsToLink = ["/share/soundfonts"];

  environment.variables = {
    DSSI_PATH = lib.mkForce "$HOME/.dssi:$HOME/.nix-profile/lib/dssi:/run/current-system/sw/lib/dssi:/etc/profiles/per-user/$USER/lib/dssi";
    LADSPA_PATH = lib.mkForce "$HOME/.ladspa:$HOME/.nix-profile/lib/ladspa:/run/current-system/sw/lib/ladspa:/etc/profiles/per-user/$USER/lib/ladspa";
    LV2_PATH = lib.mkForce "$HOME/.lv2:$HOME/.nix-profile/lib/lv2:/run/current-system/sw/lib/lv2:/etc/profiles/per-user/$USER/lib/lv2";
    LXVST_PATH = lib.mkForce "$HOME/.lxvst:$HOME/.nix-profile/lib/lxvst:/run/current-system/sw/lib/lxvst:/etc/profiles/per-user/$USER/lib/lxvst";
    VST_PATH = lib.mkForce "$HOME/.vst:$HOME/.nix-profile/lib/vst:/run/current-system/sw/lib/vst:/etc/profiles/per-user/$USER/lib/vst";
    VST3_PATH = lib.mkForce "$HOME/.vst3:$HOME/.nix-profile/lib/vst3:/run/current-system/sw/lib/vst3:/etc/profiles/per-user/$USER/lib/vst3";
  };
}
