Hi @Ygggg,
Welcome to the Sonos community. Thank you for reaching out to us and for letting us know about your concern. Let me share some information.
Your Apple TV remote should automatically learn how to control your TV’s volume without any additional configuration. If you already set up your Sonos home theater product to use your TV’s remote, then your Apple TV remote should control Sonos. If the Apple TV remote doesn’t control Sonos volume but your TV’s primary remote does, go through the steps in the help section of Apple’s support article to verify that your Apple TV remote is programmed and that your TV’s HDMI-CEC setting is turned on.
Are you using a Samsung One remote or an F-series remote? You may follow the steps in the following articles on how you can set up your Samsung remote control.
Our phone support team is closed during weekends but you may reach them from Monday through Friday, 10 am - 7 pm EST. Please feel free to reach out in the future if you have any other questions.
