I just set up a new LG 77 inch C2 Oled with an Arc, Sub (G3) and 2 One SLs, but everything is showing up as Stereo PCM, whether from my Apple TV, Xbox Series X, or PS5. I’m new to Sonos (and LG), so I apologize if this is a stupid question.
TV settings:
HDMI Input Audio Format: Bitstream
Digital Sound Out: Pass Through
eARC: On
Apple TV 4K Audio Format settings:
Change Format: OFF
Dolby Atmos: ON
PS5 settings:
Output Device: HDMI Device (AV Amplifier)
HDMI Device Type: AV Amplifier
Number of Channels: 5.1ch
Audio Format (Priority): Linear PCM for gaming or when watching a DTS-encoded Blu-ray disc. When streaming content from the PS5 or watching a Dolby TrueHD/Dolby Atmos encoded Blu-ray disc, change this setting to Dolby.
When watching Blu-ray discs, there is another audio setting that must be adjusted when you start the disc. Tap the Options button on the controller, select the “…” and change the Audio Format setting to Bitstream for Dolby-encoded discs. Change this setting to Linear PCM for DTS-encoded discs.
Xbox settings:
HDMI Audio should be set to 5.1 uncompressed for non-Dolby Atmos content and gaming. Change the setting to Dolby Atmos for home theater for all Dolby Atmos content. Enable Allow passthrough.
