So when you pause the video does the option box go away?

I'm talking about running PulseAudio on top of JACK and not the other
way around. Is that what you're doing?

I''ve done that before to port youtube audio into Pd. While it's certainly
handy it's a lot of work just to get a GNU/Linux machine to behave with
one other general audio use-case.
