TV is a Samsung LN46C750. Receiver is Yamaha RX-V667. Both are ARC audio return channel compatible. I have the HDMI cable running from port 2 on the TV as required by Samsung, but no sound on any speakers connected to receiver. The Samsung DVD player connected by HDMI to the receiver manages to get surround sound, so it has to be the ARC. I tried a different HDMI cable that support ARC just to make sure. But still no luck. Ideas?
