[Solved] QJackCtl won't start in with real time.

Hey all,

I'm having a problem with QJackCtl, I got my version from Extra. The problem is that for some reason Jack won't start in real time mode using QJackCtl. Real Time is checked and marked under the set-up tab, but that little piece of info doesn't seem to make it to jackd. If I start Jack through CLI it works with real time, but not from the GUI.

I figured this out by starting JACK from the command line and then starting QJack. When I would do that it would be running in real time just without the rest of my settings (buffer,periods,sampling rate, etc).  So in my head there's an issue with QJackCtl. I've tried to find a solution, but I can't seem to find one. This isn't the first time I've set JACK up on a system, but this is the first time I've had this problem.

The rest of the system is set up and ready to go. Rt Kernel, limits.conf and all other tuning is done.

Is there something I missed when setting this piece of software up? Any ideas?

Solved Edit:

Okay, so right after I posted this I got a crazy idea. When you enter setup in qjackctl on the first page there's a box for server path. The path defaults to "jackd". On that line I added "--realtime", so it looked like a basic CLI start-up of JACK and now it works!

So, if anyone else has this problem go to the Setup tab, in the setup window on the line that says Server Path it should look like this:

jackd --realtime

It worked for me and I hope it helps somebody else out.
