Adam from Clairmont, CA

Adam recently bought an LG OLED 65" TV. But using his Sony receiver with Dolby 5.1, should he plug everything into that first? Leo says that his general standard is to route everything through the AV receiver and then to the OLED. But if he is streaming from the TV itself, he will need an audio return channel (ARC) in order to get that audio through the home theatre system.

Scott Wilkinson recently did an article on how soundbars have the design flaw of using only a single HDMI port. But what if you have multiple HDMI devices you want to connect? Scott was reviewing an LG Atmos Soundbar, when he discovered the drawback. Looking around, he discovered the same problem with other soundbars as well. Leo says you can use Optical, and that makes sense. But Scott says the optical output is limited and doesn't support Dolby Atmos. The only thing that carries the Atmos bitstream is HDMI.

A few questions. Caller is having issues with his ARC in his home theater system. A SmarTV needs to be able to run audio from the TV to the home theater system without latency. That's where AV ARC (audio return) option comes in. But your home theater and TV has to support it. It is essentially sending the audio the other way along with HDMI system.
