It has always worked perfectly for me. I have
that box and the
"Enable system tray icon" box checked (and qjackctl saved in my KDE
session), so when I start KDE I have a small plug icon sitting in the
system tray from which I can get to the connection window, and jackd
is started and ready to go.
same for me. Added qjackctl to the KDE autostart folder (I personally
dislike seesion management) and it works very well this way (except the
USB audio card isn't available ;-) .
There's yet another option: start your jack-enabled application as a
qjackctl command line argument, `qjackctl <your-app>`. This way, qjackctl
will show up and start jackd automagically before launching <your-app> in
turn. If jackd is found already running, it will just launch <your-app>
and exit graciously.
AFAICT this feature has been in effect as far the planetccrma desktop
menus goes on all jack applications, after some kind request from
Fernando's.
Cheers.
