I want to do a lot of music editing, recording, etc. First of all I installed Hydrogen and along with it came this 'Jack'. After I use hydrogen, my system sounds stop working and start again only after restarting. I tried Googling this problem and seems like several others have this problem too. The solutions there are actually some explanations and I don't have the patience to read all those pages! What I want regarding JACK audio is:
A simple and proper understanding of what this software does so that solutions to this problem make sense. When we go to their actual website, they have all this long story of "Do you want to .... blah blah". When we go to the Wikipedia article, they straight away demoralize us with all technical terms.
How I can close it along with Hydrogen so that my system sounds return to normal (OR) How I can make all my system functions works along with JACK. In this case, Jack will have to start with every boot.
Hydrogen's default MIDI driver is ALSA (even when there is a jackmidi option); then why is jack needed at all?
