Just picked one of these up. So far, I'm somewhat impressed with the color reproduction and sharpness of the set. It can be confusing working with it though. It's an Android TV (essentially) and then there's the LG interface. But that's all another story. The reason I'm posing here (first post) is because I'm trying to find out why it's not passing Dolby Digital info to my receiver. I'm running audio from my satellite box straight to my receiver and that works so I know my receiver is ok. I'm trying to watch Amazon streaming video from the TV and am using an optical audio out cable to my receiver. I can't get digital audio. Ditto for running the Xbox 360 through HDMI to the set with the audio passing through the set to the receiver. Ditto for my DVD player via HDMI to TV. My receiver is quite old do it doesn't switch HDMI or I'd just run everything straight through it but that wouldn't help my Amazon issue. Seems like maybe there's something in a menu I may have to change but I can't find anything to save my life and can't find anything searching on the Web. The receiver is set up correctly--I double-checked. Hoping someone may be able to shed some light on this perplexing problem. Thanks.
