How do you get the Roku remote to NOT turn off Samsung tv & Samsung surround sound, Xbox &/or PS4 ? I just want remote to power on/off the Roku device.
Roku do not have a power command, only roku 4 ever did, power key on the roku remote is a tv power key. If you no longer want the remote to control your tv power, it won't control the volume either, they're connected. Go into settings> remote & devices> remote> remote in use> program tv> when the volumes mutes click NO, keep clicking NO, until it really doesn't mute it and then click yes.
Or, when you're finished using the Roku just press the Home button on the remote and use your TV remote to switch to another device. As was mentioned, you don't turn a Roku off.
