I recently picked up an LG 42LW5700 TV and a new Sony STR-DH720 receiver to upgrade my home theatre to 3D and 7.1 audio, and though I'm able to get them working properly, I've been unable to figure out how to enable the audio return channel. I know the receiver supports it, and the TV has an audio setting to turn ARC on and off, so though I can't find any specific references, I'm assuming it supports it as well. Does anybody have any tips for what settings and/or ports I should be using to get the two to talk to each other? Or am I just stuck with using optical audio (not a deal breaker by any means, but would be nice to remove a cable from the already crowded area)?
