i think i found the problem and now i dont know if it is a problem.
it seems the lfos are connected to the audio drivers somehow.
when turned off or to some specific drivers, the lfo stop. but with a little fiddling it can be started again.
also is there a way to get my “desktop-sound” ? (sry for lack of better word) meaning whatever sound is playing right now be it from music player or browser.
