I recently bought the Sonos Arc Ultra and an Apple TV 4K. I believe my setup is correct, but I can't select Atmos on the Apple TV 4K—only Stereo, Dolby 5.1, or Off.
Here’s my setup:
-
Sonos Devices:
- Arc Ultra
- Sub 4
- 2x Era 300s
-
TV: Samsung QN82Q6FNA
-
Apple TV 4K: Gen 3
Connections:
- I’m using the Sonos-provided HDMI cable from the Arc Ultra to the Samsung TV’s ARC (Audio Return Channel) port.
- The Apple TV 4K is connected to a regular HDMI port on the TV.
I also tried connecting the Apple TV to the Arc Ultra via Bluetooth, but it’s inconvenient because I have to manually switch the audio to Bluetooth every time I turn it on.
Does anyone know how to enable Atmos on the Apple TV 4K with this setup?
