"I had installed jack just before I installed these packages and so the option to fix real time permissions wasn't available." To add to this, I have run ubuntustudio-controls and I can't see an option to "FIX Real Time Permissions", possibly because I had installed Jack before I had installed ubuntustudio-audio.
I don't want the lowlatency kernel and so won't be installing it, and it seems like it's optional.
I'd addressed Len's answer with this:
