Try this (in this exact order):

Disconnect everything from the TV including the Arc. Then unplug the TV and Arc from power for a couple of minutes. Plug the TV and Arc back in but keep everything disconnected. Make sure Simplink is enabled in the TV settings and run TV Setup in the Sonos app under the Arc’s settings. Follow the instructions. When the app instructs you, connect the Arc to the TV’s HDMI ARC port using the Sonos-supplied HDMI cable. After the Arc has been successfully connected, connect the Apple TV to the TV and test again.

Hi @skodman 

Thanks for your post!

Do you have any other devices connected to the TV via HDMI? If so, please test with them disconnected - if you no longer experience the issue, then you likely need to disable CEC features on that disconnected device when you reconnect it.

I hope this helps.
