Hi Just bought a Yamaha RX-V373 receiver. Set it up as per instructions with HDMI to BD/DVD and TV, and optical to non-ARC TV. I get video, but at first the only sound I could get was via USB and iPhone - with all speakers working. Then checked the manual and followed instructions, switching on HDMI control. Now I can get sound with the TV - though sometimes it gets confused and I have to change HDMI input for it to use the optical. Nothing I have been able to do will get the blu-ray player working - it's a Panasonic DMP-BDT110EB - video works OK, just no sound. All audio on the BD is set to bitstream. Swapped cables to see if there was a fault there - none that I could detect. Anyone have any suggestions?
