I have a Roku Ultra 4K HDR on one TV and a Roku Premiere+ 4K HDR on another TV. I record OTA on a Tablo. One day I tried to play recorded show from my Tablo and it did not work #("Your Roku.is not connected to a device that support Surround sound.") It actually is and works fine on all the Roku channels included Spectrum and always did until that day. Called Tablo support and they said ROKU did something and only way to correct was FACTORY RESET the Rokus. It worked (almost) as the Ultra immediately worked but the Premiere+ did not. I factory reset 3 time and it still does not work. I disconnected woper and let sit & tried again. I have tried several different setups and always no good results. My receivers all have ARC. I am using HDMI cables. Roku not answering phones. 03 25 2020
