So I’ve just bought a new LG OLEDC155 TV along with a Sonos Beam gen 2. I get sound from watching live tv but when I play anything at all from my Apple TV 4K there’s absolutely no sound at all. Any help appreciated.
Set your LG settings to this:
Sound Out: HDMI (ARC) Device
HDMI Input Audio Format: Bitstream
Digital Sound Out: Pass Through or Auto
eARC Support: On
Auto Device Detection: On
Simplink (CEC): On
Auto Power Sync: Off
On the Apple TV, under the audio settings, set Change Format to Off and under Immersive Audio, set Dolby Atmos to On.
