I believe pipewire-jack is an alternative implementation of jack so you either need to remove jack2 or pipewire-jack.
If you don’t know which is better for your situation, I would recommend “Y”
I don’t know which is better so I will follow your recommendation, thanks Dalto
That’s odd.
pipewire-jack & co. got updated on my end, like 11 days ago:
[2022-01-07T11:09:40+0100] [ALPM] upgraded pipewire (1:0.3.42-2 -> 1:0.3.43-1)
[2022-01-07T11:09:40+0100] [ALPM] upgraded gst-plugin-pipewire (1:0.3.42-2 -> 1:0.3.43-1)
[2022-01-07T11:09:47+0100] [ALPM] upgraded pipewire-alsa (1:0.3.42-2 -> 1:0.3.43-1)
[2022-01-07T11:09:47+0100] [ALPM] upgraded pipewire-jack (1:0.3.42-2 -> 1:0.3.43-1)
[2022-01-07T11:09:47+0100] [ALPM] upgraded pipewire-pulse (1:0.3.42-2 -> 1:0.3.43-1)
I still got jack2 installed. If it’s a newer version of pipewire-jack, then it hasn’t hit my mirrors yet.
That is the case:

Noob question here. I had the same issue and I tried to remove jack2 manually with pacman (didn’t get automatic y/N option), but it didn’t work:
sudo pacman -R jack2
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)

What should I do? Just wait for mirrors update?
You need to get pipewire-jack updated which would replace jack2 and therefore avoids breaking the dependencies.
Could you post the output of
sudo pacman -Syu
?
You can’t remove it that way. You have to let the upgrade replace it.
sudo pacman -Syu

Do you have something that explicitly requires jack2?
I don’t think so.
You can always look and find out. Then you’d know for sure. . .
Not sure what was done here but I just did this and it looked like this:

I don’t know how to do this. Only command that come to my mind is ldd, but this isn’t it. I will be grateful if someone could give me some instructions how to find out whether something else needs jack2.
I know chaotic-aur isn’t the best practice, but aside from potential security risks it shouldn’t be a problem (or am I wrong?).
Run pactree -r jack2 to see what depends on it.
pactree comes from pacman-contrib if you don’t have it, install it.
Thanks. Result looks like this:
jack2

What does pacman -Si ffmpeg-compat-57 show?
chaotic-aur can create dependency issues that wouldn’t normally be issues because prebuilt packages need hard dependencies.
That won’t differentiate jack dependencies from jack2 dependencies. Although, that may not be the issue here, it was just a question.
EDIT: I triple-posted and had to moderate myself 
What does pacman -Si ffmpeg-compat-57` show?
Something like that:
