Hello, I believe my setup should work but I’m missing something. I’m hopeful someone with a similar setup can assist and highlight what I’m missing. Tv, Apple TV, and sound bar are all up to date.
Hardware:
Apple TV 4K (2022) → “4k 120fps hdmi 2.1” cable→ HDMI 1 (enhanced format) on Sony Bravia 5 2025 K65XR50
Sony Bravia 5 2025 K65XR50 port 3 eARC → same HDMI cable model and length as before → Sonos beam gen 2 (latest firmware)
Surround is 1 x Beam gen 2, 2 x ikea symphonik bookshelf speakers as rear audio, and a gen3 subwoofer.
Software settings:
Sony TV ->
sound (audio settings);
Dolby AC-4 dialogue: min
Dynamic range: standard
DTS Dynamic Range: off
audio system settings;
acoustic center: off
audio system prioritize: off
avsync: auto
digital output: auto
eARC: auto
optical digital audio output;
optical digital output: off
digital output: Auto
I can get Dolby 5.1 all day long but there is no option for atmos on the Apple TV or in apps. I swapped cables and tried full power cycles. No change. Any suggesting appreciated!’
