I'm a bit confused by your request if it's set high for a source it should be low when you select another source (as long as it's set low) or standby. Otherwise it makes no sense as a trigger. My guess is what ever you plugging in is not compatible.

Set every trigger on ever source low and set one high on one source and see if that works.
