    Exclamation Problem with qjackctl & calfjackhost

    when I run the calf audio plugin using jack host, there was no audio going in (while the audio in/out working well outside of jack.
    Later, even the calf were not working...
    the error message:

    Besides, I run qjackctl to check. It turned out to be not connected to server.

    Hi. Not sure to have really understood your problem, but it seems that jack was not launched by Qjackctl. Can you post details about your distro and how you installed jack and Qjackctl?
