Can anyone steer me in the right direction. This is the second Yamaha CXA 5200 I have purchased brand new, When I am watching TV I stream FUBO ,and also have Netflix, and watch You Tube as well. When I am watching TV and it does not happen all the time but I will be watching TV and hear a popping sound come through my speakers, BUT only the right two Front and Back Atmos speakers I have 4 they are the Rsl 34E an excellent speaker. I have also replaced my Monolith 9x Amp so I have a new amp as well. This is driving me crazy I have tested my Atmos speakers Right Front and Right Back or Height what ever you want to call them, and they are fine. The first Yamaha CXA 5200 I took to authorized dealer and he had to replace the HDMI Board, I mean what are the chances I have two Processors with HDMI board issues I am thinking maybe its an electrical issue but my processor is pluged into a furman Elite 20 Pfi power line conditioner surge protector, also the furman is pluged into a dedicated 20 amp circuit. This only happens during TV, when I play music streaming or CD's Or 4K Blu Ray's I have yet to hear a popping. Can anyone help.
