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?

Assuming this is the correct 2018 tv, your tv doesn’t pass Atmos. https://www.rtings.com/tv/reviews/samsung/q6fn-q6-q6f-qled-2018

audio passthrough

- ARC Yes (HDMI 4)

- eARC support No

- Dolby Atmos via TrueHD via eARC No

- DTS:X via DTS-HD MA via eARC No

- 5.1 Dolby Digital via ARC Yes

- 5.1 DTS via ARC No

- 5.1 Dolby Digital via Optical Yes

- 5.1 DTS via Optical No

If you want the Ultra to shine, and accept Atmos audio connect, you will either need a 3rd party device as mentioned above, or upgrade your tv to a new that supports eARC/Atmos audio output.

Check there are no updates available for Apple TV 4K, then reboot both TV and Apple TV 4K

Just checked, currently the Apple TV is on webOS 18.1 and there is not an update available.

@bigtimepower, would you be able to share some photos of the audio settings on both your Apple TV and your Samsung TV?

Have you tried going to the expert sound settings on the TV and selected Dolby Digital Plus for HDMI output? This might get you some Atmos support, but only at the lower rates supported by DD+. For higher bit rates an eARC capable TV is required.

If the Arc ultra had an additional HDMI input then that would help but Sonos don’t think of that.

If you can’t get DD+ from the TV to the Arc Ultra, then you may need to get an eARC capable TV to get Atmos.

Mr. T

Ah sorry, I had assumed you upgraded from the Arc and were previously getting Dolby Atmos, but lost the ability with Arc Ultra.

Dolby Atmos on Apple TV 4K uses a higher bandwidth and generally requires an eARC connection, unless the television can convert Dolby MAT to DD+, which very few televisions have the capability to do so.

As a minimum, as @Ian_S states, the TV’s HDMI output needs to be set to Dolby Digital Plus. If you are still unable to select Dolby Atmos on Apple TV 4K then you could look into an audio extractor, such as HDFury Arcana, or upgrading the TV.
