Audio output devices not recognized on one account

Help
1

I’m presently having a really weird issue. On my main account, no audio output devices are recognized apart from bluetooth, however creating a new account with the exact same settings results in an fully functioning audio for that account.

The only possible explanation I can think of is a setting which isn’t managed by nix getting accidentally changed. I have no idea how something like that could be tracked down, though. Hopefully the files I’ve attached here are helpful.

configuration excerpt of audio setup 
  services.desktopManager.plasma6.enable = true;

  services.pulseaudio.enable = false;
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
  };


  hardware.bluetooth = {
    enable = true;
    powerOnBoot = true;
    settings = {
      General = {
        Experimental = true; # probably needed for charge level
      };
      Policy = {
        AutoEnable = true; # default bluetooth controllers/adapters on
      };
    };
  };

I’m not sure what the exact issue is, but I’ve solved it so putting this here for future reference in case someone else has the same issue. One or all of the files in ~/.local/state/wireplumber/ were broken, but deleting them and restarting audio services with systemctl --user restart pipewire pipewire-pulse wireplumber appears to regenerate the needed files with a functional configuration.
