I have in ceiling Sonos speaker and I tried connecting my amp to MY SAMSUNG tv using the HDMI but it keeps showing me a spectrum app and I don’t even have that service as I’m not in the USA. I turned on the Arc in my Tv settings and nothing. I unplug the HDMI and the spectrum app goes away, I was told at Best Buy this would work so I did not  purchase the sound bar that usually helps to connect the tv to the amp.. please help
