I thought that everything went into the receiver from the DVD, XBox, Cable Box via HDMI and I just needed an HDMI from the receiver to the TV. What is the optical cable for? I thought that the HDMI carried both video and audio. I can hook it up the way it says in the manual but I have no idea why it needs to be so. My guess would be that if I wanted to play music from a CD player or Apple Airplay through the TV speakers??? Why would I do that when I have a receiver with surround speakers? Any quick words of wisdom/explanation?
Not sure what it says in the manual (which is hardly a stellar example of clarity in technical writing) But the optical cable is only necessary to receive sound that ORIGINATES from the TV. For example, if you have a Smart TV that has the ability to connect to Netflix or Pandora, the sound from those applications can be 1) played through the TV's speakers (obviously inferior if you have a surround system) 2) sent back, via HDMI return channel, if both your TV and Receiver are ARC capable, 3) output from the optical out (assuming your tv has such an output) to the receiver, or, lastly, if your TV has plain old (red and white stereo) outputs, those can be connected up to one of the two audio input jacks on the Yamaha. The same is true if you receive your TV signal over the air.
All your input devices (Cable Box, DVR, DVD player, Bluray player etc) should be hooked up directly to the receiver and sent along from the Receiver HDMI out to the HDMI in on your TV.
Hope that helps.
