Used it with jack2 1.9.10-6  
Strange, the version of jack2 you are using is known to cause issues
with Ardour, but actually I experienced an issue :D.  
Okay. What kind of issues are those supposed to be though, and what
exactly is your issue with ardour + jack2?
IIRC there was an issue with ardour's freewheeling export and jack2. I
don't remember exactly which commit fixed the issue.

I don't know what kuind of issue I've got. Ardour crashed, when testing
my new USB audio interface, so I continued testing with Qtractor. I've
got no time to check why Ardour crashed.

Is that jack2-git from AUR?
No, it is jack2 from git, but not the original AUR package, see my
comment https://aur.archlinux.org/packages/jack2-git/ .
