Does the sub kick in when you turn the volume up?? I don’t use active standby I leave my sub on all the time? It may not be this and just a thought?Hello. Just replaced the board in my subwoofer. Because it was not working for a weeks I have now noticed something that was properly happening before. When I turn on the tv and play a channel on sky q etc my Denon app says all the channels are being used on the output. The problem is the subwoofer is not used unless I press the sound mode button on the remote to reactivate the sound mode I am already in. Then the subwoofer green light comes on. I use dts neu x mainly. Can anyone suggest what may be wrong?
