if you havent used JACK before, its probably just a matter of not having
any experience with the tools. if you are not planning on using JACK, i
would just go back to xubuntu, but, basically, they are all ubuntu.
ubuntustudio *is* ubuntu, so if you are using the same kernel (which you
likely are, even if you installed the lowlatency one, if you didnt do
anything to select and boot it). the main difference is likely this
simple... you are clicking on applications (such as ardour) that try and
start JACK. JACK gets started, and basically takes over your audio (as it
is supposed to do).. you then have no way of going back to using the system
normally with pulse, since you have just started using JACK, and are likely
not configuring it properly (if at all)...

i would first relax, and ask yourself if you are in need of JACK. if the
answer is "no", then, dont use it. if you want to casually edit some audio
files, you can do that with audacity from inside *any* major operating
system, such as stock xubuntu without adding the ubuntustudio packages. if
you need JACK then, you would want to start from a fresh boot, and open
"qjackctl" and start configuring that GUI tool to start JACK. you would
select your audio device and click "start" and troubleshoot any errors that
come up for you in the window there.
