Guys I hope someone can help me because I really need to get this going for my particular setup. I don't want to use an optical cable because my TV is wall mounted (all wires hidden inside wall) and I don't use a sat/cable box so I really need the arc to get sound from my tv to the receiver. The setup: LG Lm7200 TV Sony STR-DA1800ES receiver Both are ARC compliant The problem: I can actually get arc functioning between the TV and the receiver. The issue is none of my other components register. So when I select my BD, ps3 or anything else I get "no signal" message. I plug into a different port on the TV that's not arc compliant and everything works fine but no arc of course. So far I have tried: turning simplink on, turning simplink off, power cycling all units, setting pass through on the receiver to both on and off, turned Hdmi control to on for receiver and confirmed arc is enabled on TV, and many other failed attempts of switching various settings around. . I know this is probably a tired subject but you guys can really make my day if you can help me with this. I've exhausted all the options I can think of.
