Has anyone gotten Ubuntu Studio Controls to work?

Apparently, Studio Controls is supposed to be a better replacement of Cadence.
And yes I've had a lot of problems with Cadence.

But has anyone successfully run it on Arch Linux?

Nothing happens when I click "Start or Restart Jack". The first time I got some logs:

So I installed `libffado` then.
After that, every time I click "Start or Restart Jack", nothing happens. I don't get any logs at all. And the (child) process is defunct:

$ ps aux | grep jack
ploppz      2689  0.2  0.1  95972 18572 pts/1    Sl+  22:01   0:00 nvim jackdbus.log
ploppz      4001  0.3  0.0      0     0 ?        Z    22:02   0:00 [autojack] <defunct>
ploppz      4248  0.0  0.0   6316  2312 pts/3    S+   22:02   0:00 grep --color=auto jack

This happens also after I uninstall libffado...
I don't really get the option "FireWire Module select" anyway, what is FireWire? And why do I have to select either ALSA or FFADO modules?
I tried to select FFADO and rebooted (it says that "requires reboot to switch") but when I reboot and open Studio Controls again, it's set to ALSA again! So much for rebooting.

Re: Has anyone gotten Ubuntu Studio Controls to work?

I had exactly the same problem and almost gave up on using it, until I saw in the Studio Controls CHANGELOG for version 2.0.0, that it depends on python3-alsaaudio.
So I installed this package from AUR: https://aur.archlinux.org/packages/python-pyalsaaudio and now everything works as expected for me including the logs written into the ~.log folder. Hope it helps. Cheers!
