I have a Samsung BD-J6300 3D Wi-Fi Blu-Ray Player (2015 Model)
and have an HDMI cable from Blu-ray out to Receiver HDMI DVD in. and a HDMI between Receiver and Top box. The only way I could get sound while watching a DVD was to set the input selection to "CD". OK, so I reprogrammed my Logitech Harmony One to direct my receiver to"input CD" instead "input DVD" and it works fine when I first select watch DVD then it automatically changes from CD input back to DVD input. If I hit the help button it changes it back to CD input. So my first question is why do I have to have "input CD" on to watch a DVD with sound (DVD works but without sound), and two, why doe the input switch back to DVD from CD with my Harmony remote?

Thanks?
