I just bought this bar yesterday. When playing certain content (PCM on certain apps, HULU and NetFlix) in cinema mode only at higher volumes there is a VERY high-pitched, unbearable squeal that sounds like microphone feedback. I did all the troubleshooting I could think of and as a last ditch effort went into the LG app on my I-Phone and turned off "multi-channel experience." That was it! I could replicate the problem by playing content in cinema mode and creating the squeal. It started and stopped repeatedly as I toggled the multi-channel experience on and off. I would ask the LG rep to look into this as I was getting ready to return the unit based on this issue. Hope this helps someone!
