See that's exactly why I'm still using Ubuntu 18.04. Even if I were to just move to 22.04 I know I'd be troubleshooting things, and even things I rarely use. Just knowing that some tiny feature is missing will drive me crazy lol.

And oh yes I am very familiar with AV Linux! It was like my learning lab for JACK because everyone online made it seem like JACK and Pulseaudio were a nightmare to get working together so I grabbed another computer and installed AV Linux, but this was back when it was still Debian based. I used that and KX-Studio as a shopping list too, and then installed everything I liked manually on Arch.
I still have Arch installed on that machine collecting dust. I have to take it apart and try to figure out why the liquid cooling isn't working.

But yes, AV Linux is awesome because it comes with so many plug-ins, tools, and DAWs/Synths pre-installed. It used to ship with the hard Realtime Preempt kernel for low-latency, but now it uses the Liquorix performance kernel. I need to give it another try because a lot has changed.

Do you ever use VM's to try out distros? That's my preferred method because it makes recording my videos a lot easier. I think I have like 30 VM's installed on this machine right now. I used to run VMware ESXi on a server here that hosted all of my VM's including my server VM"s, and I could log into it with VMware Workstation and it was just like running the VM's locally. But Virutalbox and KVM with Virt-Manager work just as well.
