My kit is in my sig. The problem I cannot solve has started after adding the Oppo UDP-203 4K player to my system. My TV has 4 HDMI inputs configured as follows:- HDMI 1 = Yamaha RX-A3010 AV Amp HDMI 2 = Oppo UDP203 player HDMI 3 = Sky Q The Oppo has two HDMI outputs. The Main one goes to the TV in HDMI 2 and carries picture only. The second Oppo HDMI output is sound only and goes to HDMI AV2 on the Yamaha. If I select HDMI 1 on the TV I hear the sound from the Oppo in 5.1 through the amp but no picture is shown on the TV. The amp shows L,C,R,SL,SR and Sub channels. If I select HDMI 2 on the TV I see the BD being played but there is no sound. The amp only shows L and R. Why is the sound only audible when the amp is the selected source rather than the Oppo? I may be missing the bleeding obvious but I just can't see the solution.
