Set up Dolby Atmos or surround sound
- Make sure that you connect your Apple TV 4K directly to the HDMI input on your sound bar or AV receiver with an HDMI cable. Most televisions don't support Dolby Atmos pass-through to sound bars and receivers.*
- Plug one end of an HDMI cable into the HDMI output on your sound bar or AV receiver. Then plug the other end of the HDMI cable into the HDMI input on your television.
*Some sound bars and AV receivers support Dolby Atmos, but don’t support video formats like HDR10 and Dolby Vision. In this case, you can plug your Apple TV 4K into either the sound bar or AV receiver to play sound in Dolby Atmos. Or you can plug your Apple TV 4K into your television to watch video in HDR and Dolby Vision. To do both, you need a television or an AV receiver or sound bar that supports both Dolby Atmos and high-quality video formats. Apple TV 4K uses a high bandwidth form of Dolby Atmos that doesn’t work over ARC connections.
