Microphone issues. On Linux, using pipewire and pipewire-pulse. Firefox 110.0 (64-bit), stock/default profile.

Microphone works on https://mozilla.github.io/webrtc-landing/gum_test.html, although it seems there is a non-ideal filter, noise reduction going which "cuts" my voice.

Microphone does NOT work on meet.jit.si, app.element.io, etc. When I check with pulsemixer and/or helvum, I see Firefox connects to the correct audio source (the microphone/input), but at "best" I hear some noise on the other device.

This is also an issue on Chromium, with the additional issue that on it the GUM test does not work. So it is not a Firefox specific issue, but a Web browser issue?

When I capture/record the mic with a native system app (e.g. ffmpeg -f pulse -i my-mic) it works okay.

I’ve been using pipewire + Firefox + jitsi without issue fwiw (not sure about pipewire-pulse)

nice, so it is really an issue on my end/setup. i do not have any config files on ~/.config/pipewire or ~/.config/pulse. my nix audio config is

{
  # Disable ALSA.
  sound.enable = false;

  # Disable PulseAudio sound server.
  hardware.pulseaudio.enable = false;

  # PipeWire
  # (rtkit is optional but recommended)
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;

    jack = {
      enable = true;
    };

    pulse = {
      enable = true;
    };

    alsa = {
      enable = false;
      support32Bit = true;
    };

    wireplumber = {
      enable = true;
    };
  };
}

specific webapps on firefox are not working ? Have you tried other things on firefox (like call.element.io, or bigbluebutton if you have access to an instance)

In reply to @Minijackson:matrix.org
I just don't have the alsa.support32bit, but it shouldn't matter for Firefox

My profile is also very similar I think (though I don't have rtkit or wireplumber enabled). I'm also on GNOME - not sure if the desktop audio routing has anything to do with it?

In reply to @Minijackson:matrix.org
I'm also using pipewire from the unstable channel, not sure if it changes things

Minijackson: i just tried with nixos-gnome-22.11.2720.50c23cd4ff6-x86_64-linux.iso

didn't work either. i tested on meet.jit.si and web.whatsapp.com. again, only https://mozilla.github.io/webrtc-landing/gum_test.html kinda worked
