Help with eARC

[Stryker]

Ok, so I have a newer 65" LG OLED TV (2022) with eARC HDMI port. I have a Samsung Q-60C sound bar with wireless sub. I connected an HDMI eARC compatible cable from the TV eARC port to the eARC on the sound bar. In the TV audio settings it see's the eARC connection and the sound bar shows DIN - DTX virtual X on it's screen yet, I am getting NO sound period! I had to eventually switch to a digital fiber optic cable just so I could get audio. What am I missing here? I am using Roku for TV and have a Sony blu-ray player (no sound what so ever with this device as well). HELP audio guru's!
