On 2 of my 3machines it works like a charm. On one machine (Debian Trixie) it ist still hanging, but it looks as if it's finished with jack. On Qjackctl there is no Qtractor left and I can gracefully close other applications like Qjackctl or non-mixer-xt.
And it makes no difference anymore if I close non-mixer-xt before closing Qtractor, or if I start Qtractor without non-mixer-xt.
So at least jackd is in a working state. This is a progress.
But what ist Qtractor waiting for?
I started Qtractor with strace and copied the output up to the state where Qtractor isn't seen anymore in Qjackctl and hangs. See attachment.
