Missing audio completely

All of a sudden, I have no audio. I had it yesterday, gone today. I have no audio controls in Gnome. When I try and check on pipewire, it’s masked (so is wireplumber):

$ sudo systemctl status pipewire.service
○ pipewire.service
     Loaded: masked (Reason: Unit pipewire.service is masked.)
     Active: inactive (dead)

I didn’t manually mask it. Why would this be?

My config is:

# Enable sound with pipewire.
  sound.enable = false;
  hardware.pulseaudio.enable = false;
  security.rtkit.enable = true;
  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;
    wireplumber.enable = true;

  };

I have audio = false as that’s what I’ve read online when using pipewire. But, I’ve tried false and true with no difference in outcome.

Found this in the journal:

Dec 08 11:37:27 stanton pipewire[1448]: default: can't setup properties: No such file or directory

You should check the status with --user flag, as pipewire is a user unit:

$ systemctl status pipewire
○ pipewire.service
     Loaded: masked (Reason: Unit pipewire.service is masked.)
     Active: inactive (dead)
$ systemctl status --user pipewire

Egg on my face. Config file was put in user directory, completely forgot about. I was trying to fix a static issue I have with an external speaker. Sound is back. Static issue is something I’ll pick back up another day.
