looks like some other app was using the sound card when you opened jack control.
Jack did not like this and quit.

did you have any other applications open that use sound?
close them if you did.
also turn off any sound settings for the desktop.

run jack control again.

if this may have to be run in a terminal session if you can not get all apps to stop using the sound card.

Now where was i going? Oh yes, crazy!
