Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
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
I agree, factory reset, make sure on tablo, when rescanning channels, that you check at least 3 channels of the main, here in Philadelphia it is 3-6-10. make sure check the antenna. We had to get 2tb hard drive wd and never had a problem. My mom watches OTA and she will tell me if there is a problem. On the tablo, click that blue button 3 second tap really quick to reset the tablo you should be fine, contact tablo support they rock, I have had awesome experiences with tablo. best dvr box to use, no more paying subscriptions and better than cable and satellite.
Make sure the router is 5-8 ft away from that device too.
