I thought that Pulseaudio was not delivered with Fedora 37 (which I installed from scratch). But I see that there's a "Pulseaudio" line that I can select as audio system in Ardour's and Zrythm's settings... On the other hand, when I type "pulseaudio" in a terminal, it returns that it's an unknown command and suggests me to install the "Pulseaudio" package... So I'm not sure about anything.
(I've been on Linux for some months only... so I'm not a veteran yet...)

DAWs just mention "JACK", and qpwgraph gives no info about this. But I suppose it's Pipewire JACK, as :
- pw-jack command works
- jackd and jack_control commands are unknown
- The qpwgraph app is undertitled "A Pipewire Graph Qt GUI Interface"

I didn't touch anything, and I'm not sure what settings we are talking about. In Ardour's Audio/MIDI settings, I can only choose the sample buffer (which is on 1024, as default). It also shows a red message saying that JACK is already running, and that Ardour is going to connect to it using the existing settings.
I search on the internet but couldn't find further ways to investigate on Pipewire JACK's settings.
Thank you for your help. Please forgive my newbiness.
