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";
  };
}

Does anyone know how I can pipe my mic+ardour master output to an app (Google Chrome/Discord/...) ?

In reply to @gdesforges:matrix.org
I tried "connecting" my ardour output to google chrome input with qjackctl but it was not enough

slightly unrelated
i've added an effect in easyeffects, it crashed, and now no longer starts
(killed, returns 137)
i've not found the local config for that, so it seems like i can't undo adding the effect
and maybe related, audacity takes forever to start, but starts in a pure nix-shell
