Trying to enable pipewire, audio not working

Help
1

So on my machine I’ve added


  services.pipewire = {
    enable = true;
    pulse.enable = true;
    alsa = {
      enable = true;
      support32Bit = true;
    };
    config.pipewire = {
      "context.properties" = {
        #"link.max-buffers" = 64;
        "link.max-buffers" = 16; # version < 3 clients can't handle more than this
        "log.level" = 2; # https://docs.pipewire.org/#Logging
        #"default.clock.rate" = 48000;
        #"default.clock.quantum" = 1024;
        #"default.clock.min-quantum" = 32;
        #"default.clock.max-quantum" = 8192;
      };
    };

And yes, I’ve removed hardware.pulseaudio and sound.enable

However no sound come out of my speakers.

journalctl --user-unit=pipewire --user-unit=pipewire-media-session --user-unit=pipewire-pulse -f                                                                                                                                                                     ✔

Nota that sound with pulseaudio works fine, I just want to try out pipewire.
Where can I begin to fix this?

So I’ve reenabled pipewire, and the problem seems to be:

  • While the rear altoparlants works, the front ones do not work, forcing me to use “Stereo sound” instead of “5.1” I’ve been using
  • The kde audio settings keep freezing after a few minutes open. This did not happen before.

Hi, did you ever definitively fix this? I’ve been trying for a long time (<-- just my latest plea for help) now. Here’s my config.

I also ran the same journalctl command you did and the output is here.

Basically, the problem is, no sound and the audio icon the KDE Plasma tray just says “No output or input devices found”. Would be amazing if you could advise.

Same exact issue with PulseAudio

I cannot help you,as my audio works with both PulseAudio and Pipewire and so my problem is different.
Begin with

  sound.enable = true; 
  hardware.pulseaudio.enable = true;
  services.pipewire.enable = false;

To begin troubleshooting with PulseAudio.
Also please begin a new thread.

Ok good idea, will do. Thank you.
