@aedcce HI!
Welcome to the Roku Community! Glad you're here.
I'm happy to inform you that a Roku Streambar must be compatible with the TV brand you have chosen. To use the Roku Remote to control the TV, we must set it up. Here are the steps: Home > Settings > Remotes and Devices > Remotes > Set Up Remote For TV Controls. Need further details? Click this article. How to set up your Roku voice remote to control your TV
Wishing you success! 💜
