Comment 2 for bug 1841746

ubuntustudio-controls and ubuntustudio-audio-core were automatically installed when I installed ubuntustudio-audio. I had to manually install ubuntustudio-audio-performance-tweaks.

I had installed jack just before I installed these packages and so the option to fix real time permissions wasn't available.

Before reinstalling my system I had previously tried using the GUI installer but encountered this bug https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-installer/+bug/1839182
