I have a BS SE setup. I can't get the sub to work! It was working a few months back, but I've not used it since. Without the audio rca cable connected; When I power the sub on... I immediately get a green light. If I leave it idle the light turns red. Green light active Red light no input If I connect audio cable to sub and amp and don't play any thing the light switches back to green, if I leave ideal the light goes red. If I then go on to send sound the sub light goes green, so it's getting the signal but I get no sound?! Connected to a denon avr2000 Any one offer any advice please? The unit is under 2 years old, hardly used.
