Lost Laptop Audio

Help

Dear all,

Ik have lost my adio output devices, Gnome just reports “Dummy output”, which even completely disappears upon a systemctl restart --user pipewire.service.

Here is some information:

Any ideas? It has been working normally for 2 years now, this is my config:

  # Enable sound with pipewire.
  sound.enable = true;
  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;
  };

Attaching a USB headset does work as expected, so it is only the Laptop audio that has gone missing.

Is there an older generation with which the problem does not manifest?

3

Perhaps there is an entry in Grub indeed, but there is not another version of the configuration.nix because that has stayed the same over the last months.

Do you want me to check on earlier “checkpoints”, and run the same commands, would that help?

4

Whether the same commands or however way is most convenient to find out whether this problem exists. If you find an older generation in which this problem does not exist, then we’d have reason to believe this is caused by a change in nixpkgs.

5

Ok, thanx I will check some earlier versions later today and post here.

6

If it occurred after a NixOS-/kernel-update, it’s probably a (known) kernel-bug.

Workarounds: Use a different kernel or a kernel-patch, as described in:

This looks very similar indeed, looks like a fix is on its way, I’l sit this one out then, thanx!
