My experience with PipeWire so far: Works mostly as a drop-in for PulseAudio, but echo cancellation is absolutely undocumented and even worse to setup than in PA.
The thing that kills it for me however is, under the SLIGHTEST load the audio starts stuttering and crackling, which is absolutely unacceptable. I'll poke it for another hour or so and then go back to PulseAudio, because, srsly, one job.

To eliminate a hardware issue (it's a new device), I should probably try pulseaudio for a day to see if it also stutters.

Switching back to pulseaudio and after one day I did not hear a single stutter while listening to music and working, so I'd say this is indeed a pipewire issue.
I'm too exhausted from linux shenanigans to tackle this problem this month, especially since pipewire does not actually benefit in any way.

@rash what distro?
I'm using Fedora, they switched to Pipewire in F35. Was very sceptical, but worked out of the box. No hassles.

@skyr ArchLinux. Yesterday I noticed that it actually does not run with nice -11, I needed to install rtkit. Might still be some config missing perhaps, but the arch wiki does not mention anything.

@rash Unfa's on Arch, too. Worked for him as a drop-in replacement, but over the course of 2 months, he experienced some issues which made him switch back youtube.com/watch?v=RvWgm6aZTQ (that was last November).
If you have such profound problems, it's either just you ;-) (some misbehaving oder badly-supported hardware, perhaps), or Arch fulfills my personal prejudice (I was never happy with it, stuff broke constantly)...

@rash used it as a drop-in on my arch and my colleagues didn't report any problem so far. And the load is high on video calls.

@rash
Well, I am sad to hear, that you had this experience. Pipewire works flawlessly on my machine and I never want to go back to pulseaudio/jack/smth config hell and erratic behavior in audio device selection.
Hope that someday you will try again and will have a better one.

(I recommend using up-to-date or rolling distros, as newest pipewire patches fixed many issues for me)

@rash Ich hab auf der Workstation jetzt ca drei Monate pipewire ohne Probleme bei Last. Auf dem ThinkPad das schneller mal mehr Last hat hab ich es erst seit gestern, gut zu wissen dass das ein Problem sein könnte.

@rash I have crackling sound whenever there are sources and sinks with different bitrates involved. Didn't have the time/motivation to investigate or to switch back to pulse though.
