Im currently experiencing a problem with my surround sound that is driving me crazy. All speakers work fine. When I run a surround test through youtube on roku or through youtube on the home theatre player itself and also a calibration disc everything goes fine until it gets to the rear surround speakers. The sound will play but it plays through the front coordinating speaker as well. I have ran test tones from the home theatre player menu and that works fine for all speakers. Ive updated all systems, tried running hdmi to tv then to home theatre player through arc, and also direct to home theatre input. Same results every time. Here is my setup Roku premiere plus connected to tv via hdmi Tv lg 65uf6450 with arc channel connected to home theatre via hdmi Home theatre lg lhb755w 5.1 surround sound

Any help would be appreciated!
