Recently moved my boyfriends tv from his old apartment back to his house and into his bedroom. Had to buy a new remote for it because we lost the old one. The new remote is the simple remote without the volume button. The volume on the tv will not work whatsoever. I feel like I’ve tried everything!!! Picture works fine, literally just no sound. I have the Roku SE streaming device as well
If you want to control your TV's power/volume/mute with your Roku remote, you'll need one with those controls (a simple remote doesnt have those).
Otherwise, you'll need to use the TV (or universal etc) remote to control the TV's volume.
