This unit is a complete mess when trying to use it with the HDMI-EARC. I had one for just over a year and it wouldn't work reliably with my Samsung 65" TV. I finally took it back to Costco for a refund.
Buyer beware.
Can you explain more? i have a 65 inch samsung SU8000 or something like that. I really like this price and may pick it up. No sound? static sound? delay?
