Setting up my Yamaha R-N803. Stuck on how to get sound from TV to receiver. I connected optical cable to optical output from TV to optical input to receiver. No sound. Message from set-up says 'Not available'. Double checked physical connection with optical cable, and cable is connected.
I have iTunes on my Mac mini connected to receiver using ethernet cable, and this works fine over AirPlay. Tuner also plays. Speakers and headphones work.
Don't know what to do from here and would greatly appreciate advice. I found no threads about the r-n803, so I suspect I'm not searching the right way, since this is a fairly popular network player
