I am unable to watch Showtime and Apple TV as I only hear a loud buzzing. It’s the only 2 premium stations that I have. The buzzing does not happen on the free channels on my Roku express so I am able to watch other channels just not Showtime or AppleTV. I can watch Showtime on my same tv using the Showtime app from my iPhone with Chromecast but not on Roku. My tv is old but the Roku express is new.
