I'm confused. It's possible to start Jack1 with real-time priority, when
another app captured the device, even, when the user isn't in the group
audio?  I experienced that when an app captures the device, that Jack
can't be started anymore, but the OP can run Jack1. Can you send a link,
where such a situation ever was a thread at LAU?

Don't get me wrong, it might be possible that this could happen, I
simply missed, that this ever happened.

Regards,
Ralf
