Thanks for the datapoint. I've been following https://github.com/NixOS/nixpkgs/issues/102547 and considering trying it out for a while.

Did you just set services.pipewire.pulse.enable=true?

My major concern is that I use PulseEffects as a key component of my setup so I'll need to check if that works well with PipeWire. But the only way to be sure is to try it!

I also have Pipewire running on NixOS. This is what I recommend configuring:

  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    jack.enable = true;
    pulse.enable = true;
    socketActivation = true;
  };

That allows me to run pretty much any application that uses ALSA, JACK, or PulseAudio.

That gave me "services.pipewire.alsa" does not exist on 20.09; does this require unstable?

I believe so, I am on the unstable channel.

https://github.com/wwmm/pulseeffects#note-for-users-that-did... Pulseeffect has only support for Pipewire since version 5 and Pulseaudio in the legacy Pulseaudio branch

I didn't get to try it under PipeWire on my Arch laptop before that died the other day, but a friend had said PulseEffects is no longer such a massive CPU hog under PipeWire, so much so that they run it all the time now.

Interesting. I have PulseEffects running all of the time on PulseAudio and don't notice much CPU usage. However maybe that is because I only apply effects to the mic and it seems to disable itself when nothing is recording.

I just tried it on NixOS and the new version is already packaged and working.
