I just purchased this amazing TV yesterday. It is amazing and I love it so far, except for one somewhat huge issue. I have a Pioneer SX-315 5.1 Surround Sound receiver that has a digital in (optical). When I run my optical cable from my optical out on my TV to my optical in on my receiver, I don't get sound to my receiver when I'm using an HDMI connection. My Video 1 (S-Video and A/V sound) connection gets sound to my receiver via the optical port, but HDMI doesn't. There has to be some sort of a setting I'm missing, because I'm swapped out everything in the equation and double check the equipment to make sure it all works, and everything is good. I contacted Sony Support and the lady (who didn't sound like she knew her left foot from her right) said I needed a connection to my coax on my TV to get the optical to work for my HDMI inputs. Doesn't make sense to you either? Didn't think so. Anyone think they can help me out here, thanks.
