Re: How is PipeWire working out for you?

Hi Keith,
First of all thanks for the detailed feedback, more inline:

    Hi Christian,
    I've been exclusively using pipewire and been happy with it.  It
      has provided me with low latency and seems to identify all of my
      hardware correctly.  Using Carla, I'm able to re-wire my audio to
      fit my current workflow.  There have been some issues:
    - When freewheeling wasn't implemented I was shutdown from
      rendering in Ardour for a couple of weeks. That's now fixed
    -Ardour seemed to be unstable with pipewire. That's from both my
      experience and what I've read on various forums.
    
You say seemed (as in the past), but I get the understanding here that this is still the case for you right? 
-While App developers tend to try to be helpful, there's not a
      wide acceptance of pipewire yet.  A common response is to go back
      to Jack, or switch to alsa.  I've come across several individuals
      in forums who advocate to everyone to avoid pipewire and stick
      with jack.
Yeah, that is always going to be a challenge, hopefully as PipeWire gets wider adoption and further improves the resistance will fall away. 

    -I switched to Reaper, but Reaper fails to reconnect everything
      in pipewire.  This is annoying as every time I restart Reaper, or
      render in Reaper I have to go into Carla and reconnect my sources
      and sinks.
I have no experience with this, but can I assume that what you are saying is that Reaper do reconnect everything if you use Jack? Or is it just that Reaper in compared to Ardour doesn't reconnect everything? 

    -Reaper has no way to set pipewire buffer size and I couldn't get
      jackCtl to work to control it.  Apparently this works with Jack? 
      My work around is to define the environmental variable to set
      pipewire buffer when evoking Reaper from the command line,
Does the workaround from Wim in comment 9 fix this issue for you? https://bugzilla.redhat.com/show_bug.cgi?id=1949421 

    
    -Gucview no longer saves audio under pipewire during video
      recording and there seems to be no progress, or even
      acknowledgement of where the problem lies.
Ok, something that needs to debugged further 

    -I customized alsa-monitoring to rename my audio interface and
      its ports, but upon updating pipewire all the customization was
      overwritten.  The update did back-up the original file, however
      having to re-do the customization every time pipewire updates is
      annoying
Ok, also worth looking into what we can do. 

    -Finally, I wish there was a set of good quality GUI utilities
      specifically for pipewire available from Fedora repository. I
      believe such utilities would go a long way in giving the
      impression that pipewire is polished and a worthy replacement for
      Jack and pulseaudio.
Agreed, it is an area where I hope the community will step up and help though as Wim got limited time and thus things like these ends up getting pushed down his priority list. 

    
    I hope this helps,
It is very helpful, thank you.

      Hi everyone,
        So we have been shipping PipeWire for a bit now and Wim has
          of course been pushing out regular updates with bugfixes and
          enhancements. So I am not a pro-audio user myself so I wanted
          to ask how things are going, is PipeWire usable as a daily
          driver for ProAudio folks now or do you find yourself
          reverting to Jack ?
