I’ve looked through all the threads and can’t find anything so, I figured I’d ask. I have a 2016 Lg tv model # 65UH6030 with a rca 2010 model #rtb1023 blue ray surround sound. I can get the speakers to work with dvds but not with the tvs like everyone else but I have the HDMI plugged into Arc port still nothing. I tried the red and white rca jacks still nothing I tried changing the mode on my tv audio out still nothing so if anyone had some advise I’d appreciate it!
After connecting the optical out from your TV to the two seperate white and red AUDIO IN connectors, you have to switch the source on your RCA player to "AUX".
(On the remote is a button "AUX") That´s for external Audio. It´s not possible via HDMI with this RCA player, sorry.
