Hi,
I've been able to use StereoTool with Jack on Ubuntu 16.04 LTS without any issues. I've disabled PulseAudio in order to get Jack to work. When I try to start StereoTool 8.30, I see this error and StereoTool does not start. Jack is running and holding onto ALSA directly. I need to Jack to feed the output of VLC and to connect a silence detector.
Code:

Is there a command-line option to force Jack-Only mode?
Thanks.
