I've tried everything and I can't get any sound other than the main TV speakers. The HDMI Arc and optical audio output modes do not work. I had a 2016 LG Oleg TV and was able to get it working without any problems. Also, this newer model is darker than 2016. How did it happen? LG 2021 model. Year of failure for LG. I would return it if I wasn't too lazy to take it off the wall and box it up. Too much work. Just a loss for now.
