I have the LG 49UB8500 for a few years now but I just now bought a receiver with a HDMI ARC port. I connect the HDMI2 port on the tv which is labeled ARC to the HDMI ARC port on the receiver. On the TV, I changed the Sound Out to "External Speaker (Optical/HDMI ARC). However, there is no sound out to my receiver.
Does the ARC function on this TV only works with LG sound bar or it works with other receivers as well? I know Bluetooth only works with LG bluetooth headphones. I wonder it's the same case here with HDMI ARC.
