HDMI ARC PROBLEM SOLVED

I have a Sonos beam and a Samsung Smart TV that’s a few years old. I spent probably ten hours and came minutes away from buying a new TV before I resolved this issue but I fixed it. Issue was that the HDMI ARC port said it was not recognised and TV would default to TV Speakers. Would work sometimes then not. I FINALLY looked into the cable box I was using (in my case Telus TV) and there is a common issue with the HDMI ARC when you have a cable box and other devices connected to the same TV and the sound bar is on HDMI ARC. There is a CEC prong in the HDMI cable to the cable box (or perhaps game console, whatever)  (I forget which pin but google it) that causes ALL these issues. You can either 1) try and remove or block this pin or 2) what I did is I bought a $20 CEC Less HDMI adapter and connected it between my cable box and regular HDMI port. Boom problem solved. I have never posted in a community before but I spent HOURS & HOURS on this issue and almost bought a new TV so I hope this helps someone.
