Indeed. I have no idea what Jack is, but it is there, in /usr/lib64.
But what happens otherwise if I remove it?

If it came as a dependency, something might stop working by being
uninstalled. If it came as a recommended package, something obscure
might no longer work, but you might well not notice it unless you do
obscure things. Try removing it and check that it isn't going to take
anything else with it. If it is, then it was a dependency, and it's up
to you to decide whether you can live without whatever else is going to
be removed or cancel the removal.

Jack is handy for music production, as you can often use some of the
features of your sound card which might not be supported by ALSA alone.
e.g. some sound cards have more flexible routing than ALSA supports, so
you could do multitrack monitoring in a way which eliminates the latency
you would get if the monitor channel were subject to the same delay the
recorded signal is. It's a bit like having a patch panel, hence the
name. It's essential in a recording studio, not so common in home music
systems. It also helps to know how to use it, as if you don't you
probably aren't getting much benefit from it.
