I just unboxed and connected a new roku premiere and hooked up to my less that year old tv, and have very slow or garbled noises coming from the tv when using any apps. Best way to describe it sounds demonic. I have tried using a different hdmi plug and no results. I have deleted the app and reinstalled. Tried changing audio formats. Have used the * button to turn volume mode off, but it was already. Any other options? I just purchased this.
