Sonos Arc
Question about Sonos Arc
Hello together Maybe someone can help me. I am using the LG OLED65CX, the Nvidia shield pro and the Sonos Arc with 2 ONE SL as rearspeakers. I used the HDMI cable supplied by Sonos as the connection from the TV (HDMI eARC) to the Sonos Arc. I also adjusted the following in the TV settings: HDMI eARC --> on Audio output --> HDMI ARC Digital audio output --> pass through Adjust AV Sync --> Bypass Now when I start playing movies from Netflix or Disney+, which according to the info have DolbyVision format, the Sonos app shows me Dolby Digital Plus 5.1. However, as far as I know, this is not the full Dolby Atmos (but compressed). Or am I wrong here? By the way, it doesn't matter whether I stream it from the Shield or directly from the TV. Can you tell me if I need to adjust anything else or if I am fundamentally misunderstanding or doing something wrong? Thanks for your help. Greetings
Dolby Atmos sound is almost only available for the original English sound - and only for a few films/series. The exception here is "Dark" season 1. Dolby Vision is a picture format and has nothing to do with Atmos.
Hi, I'll expand on the answers a bit more, namely: "If you play a film/series via Netflix/Amazon, then "only" Dolby Digital Plus" comes out. This can then be Dolby ATMOS sound via HDMI-ARC on the Arc.
If, on the other hand, you play a film with Dolby TRUE HD via BD/UHD, then the device and the TV must have an E-ARC HDMI and then plays full Dolby ATMOS without compression.
Conclusion: via EARC and Dolby True HD Atmos you have uncompressed ATMOS sound, while with normal ARC or via streaming services only Dolby Digital Plus Atmos comes out, which is somewhat compressed.
And yes, Dolby Vision has nothing to do with sound but with picture.
PSPS: Make sure that your devices (including the TV) send out the output signal or pass it through the TV (passthrough) in such a way that ATMOS can arrive at the ARC :-)
Have fun :-)

From the Sonos website:
Dolby Atmos (as in "atmosphere") is a format that allows sound to be heard in three dimensions - even from above! (Arc achieves this by reflecting sound from the ceiling). To facilitate this experience, Atmos information is contained in an audio wrapper (known as a codec) that contains metadata that instructs the audio drivers how to control the sound in your room.
Arc-compatible codecs that include Dolby Atmos include Dolby Digital Plus, Dolby TrueHD and Dolby MAT. Most streaming services with Atmos content use Dolby Digital Plus, while Blu-rays typically use Dolby TrueHD or Dolby MAT.
