Hi Christan,
I also responded inline below:
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?
The main issue with Ardour is that the plugins I wanted to use
(vital synth, sfizz) were constantly crashing Ardour. I switched
to Reaper about 3 weeks ago and haven't played with Ardour since.
Reaper, besides having a ton of features beyond Ardour, seems very
stable with plugins. It doesn't use pipewire to internally
interconnect and show up in Carla as a single block with just
hardware in/out ports
-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.

Also, please let me know if I said something incorrect.
-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?
Since i do not have jack installed I can only guess at what jack
users are experiencing. I haven't found anyone complaining about
reconnection issues. Ardour was good at reconnecting, Reaper both
randomly re-orders its ports and seems to randomly reconnect up to
the wrong sources and sinks. I haven't files a bug report with
them because its difficult to explain, and a course I use
pipewire.
-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
I don't think this is related. When you select jack as the audio
backend in Reaper it no longer provides a means to change the
buffer size. I tried setting it in QJackCtl first, but that
didn't seem to work. I since added
bash -c "PIPEWIRE_LATENCY=256/48000 /opt/REAPER/reaper" %F
to the advanced setion of the KDE launcher Reaper application and that worked. (except I can't change it on the fly, which would be nice).
To tell the truth, I'm not sure how to debug this very well
-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 ?
