I am still having problems with jack and qjackctl, I just re-installed it. When I start jack, a playing Youtube video stops untill I stop jack. Also, there is no sound or midi in Reaper when I use jack as engine. This is Linux Mint 19.3 Cinnamon
Somehow, after a reboot the error messages in qjackctl are gone, but jack is not working (no sound in Reaper). The strange thing is, when jack is started, it stalls my vidoes untill I stop jack. Something is till very wrong here. Can I somehow re-install jack?
I had jack working ok with qjackctl on my Linux Mint (19.3), but I had to install libjack-dev to compile a program. After the install qjackctl was removed from /usr/bin
So I installed qjackctl again, but now if I want to start jack, it gives an error: Could not connect to JACK server as client...
