Headphones turn on automatically and I have no sound. I believe my neighbor has wireless headphones that are connecting to my tv. So frustrated that I think I just need to move away from a Roku tv and purchase a new one. Mine is not that old but o can never watch anything because I have no sound. Please help
Go into the Settings/System/Advanced system settings/Device Connect and disable it. Note that this also disable the hotel/dorm connection function, but shouldn't be an issue with a Roku TV. you don't normally cart one along when traveling.
I'm not guaranteeing this will fix the problem, but it should stop an unauthorized set of headphones from connecting.
