Sonos Arc: How to Play Dolby Atmos

Показать описание
This video several strategies for troubleshooting why Dolby Atmos and/or Dolby True HD is not playing on the Arc. You might be running into issues streaming or when playing a blu-ray. If so, I suggest watching

Clarification: regular ARC is sufficient for streaming Dolby Digital+ (lossy Atmos). eARC is needed when playing Dolby TrueHD lossless Atmos (typically via BR disc). Could have made this more clear in the video.

Chapters:
0:00 Intro
1:47 Atmos via blu-ray
3:46 Atmos via streaming

Bro i had the Sonos Arc for like 3 months before i realised i had been playing stereo-PCM....
I was wondering why the APP showed "stereo-PCM" when i was playing ATMOS content on Netflix etc.
Activated "Pass-Through" on my TV and the entire soundbar almost exploded. It was like the heavens opened.
So happy i figured it out 😁

Good video! I have the LG B9 OLED, Apple TV 4k and the Sonos ARC, but when I got it all set up, tv shows that would normally have Dolby Atmos were only showing 5.1 on the Netflix App (running on the Apple TV). It was driving me crazy (especially when I saw that the Netflix app build into the B9 was in fact outputting Atmos through the soundbar), so I called Sonos support and the tech had no idea what to do, so he transferred me to a tier 2 person who was actually able to help. He said that there's a known issue where the Apple TV 4k is not always able to output Atmos to the Sonos Arc (Sonos are working on it with Apple apparently to fix it asap, he told me) - he made me turn eArc off and back on on the television, change Bitstream to PCM and back to bitstream, power cycle the Sonos and the LG B9, and only after all of that I am finally getting Atmos. So if you ever have someone with an eArc TV or LG OLED, and an Apple TV 4k saying they are not getting Atmos on their Sonos Arc, that's what I had to do to make it work. Thanks again for the detailed vid.

Hello do you think that the TV Sony KD-75XE8596 works with sonos arc for Dolby Atmos ?
i bought it and i think the sound of it is great but i tried it on netflix and it only shows on Underground 6 that its 5.1 not dolby atmos it never shows Dolby Atmos not even on the sonos app.
Do you think i have to get the Fire TV Stick 4K which has a great price 50€
or the Apple TV 4K which is 150€ more
I dont know whats the best for dolby atmos?
And btw i only have a Arc port on tv unfortunatly not eArc or schould i connect it to optical audio Output cable?
Need help to get Dolby Atmos

Hello Daniel, I have a 3 year old Vizio E60u-D3 which I plan to upgrade this year. However, I am in dilemma to get a $2000 TV that doesn't work with my Apple TV and Sonos Arc Combo. 2021 Vizio P series Quantum X has eARC support but it does come only with DTS Virtual-X Audio support for its Audio output. Do you think eARC will passthrough Dolby Atmos for Apple TV 4K(5th Gen) even though TV it self doesn't support it ?

Hello Daniel. I hope you can clear this up for me. I have this setup: Sonos Arc via eARC to LG CX and Apple TV 4k via "normal" HDMI input to LG CX. There's only 1 HDMI input labelled eARC/ARC behind the TV andI don't know what to call the other HDMI inputs. My questions are: one, will I be getting Dolby Atmos from streaming Netflix on the LG CX itself? and two, will I be getting Dolby Atmos from playing Netflix on the Apple TV 4k even if the Apple TV 4k is not plugged in the eARC-labelled HDMI input of the TV? By the way, I'm using high-speed HDMI cables but as I've mentioned, only the Sonos Arc is plugged into the eARC input of the LG CX. I'm so confused.

Hey I have the 2020 LG CX TV with the Sonos Arc. The app displays Atmos but there ist only good Sound but there is absolutely no atmos feeling....I tried Netflix Dolby Promo Videos with the PC but there is no Atmos feeling. I tried to change the position if the arc. I got a rectangular living room. There should be at least a lil bit atmos feeling.
Do you have made the same experience?

Great video!! May I ask if you an old 2015 Samsung tv and it has arc not earc, will an Apple TV 4K Netflix app sent Dolby atmos (dd+) to the Sonos Arc or it needs earc or the tv to supports Dolby atmos in order to pass through and sent the audio to sonos arc?? Thanks

Thanks for your very informative review.
I'm curious to know though, whether a Sonos Beam Gen 2 can be connected to an Apple TV 4K in the same way that HomePods are connected - i.e. using AirPlay 2.
I have an older TV that does not allow Dolby Atmos to pass through from a HDMI input to my HDMI ARC port.
Therefore I need my Apple TV 4K to connect directly to my speakers using either AirPlay 2 or HDMI input (which the Sonos does not have).
I'd prefer to use Sonos if possible, so I can extend the system in the future by adding a sub and the new Era 300 rear Atmos speakers.
If this is possible, would latency be an issue? Or would it be just as good as using HomePods?

Hello I have a tv which has earc feature. When I was watching doldy atmos trailer in YouTube, I can only see ‘Dolby digital plus 2.0’ but not ‘Dolby atmos’ in my Sonos apps. I changed the tv setting to earc mode but the problem was still there.

Is it the problem of the YouTube trailer? Is it a must that I have to watch Netflix so ‘Dolby atmos’ will pop out on my Sonos apps?? Sorry that I don’t have Netflix subscription at the moment.

Thank you

Enjoyed this video. Nice background on your studio as well.

One of the nice things about the magic of advanced positional audio is that it can sometimes create a 4D effect. A bomb went off right behind my wife’s ear and she punched me. I have to fine tune the delay to get it synced better but it felt like I was truly there.

I have the Arc, Apple TV, and Sony Bravia TV. The Arc is connected to the eArc port on the TV and the Apple TV is wired to the Bravia.

When I play content from the Apple TV should I route audio to the TV or can I AirPlay to my Sonos system (Arc + sub + One surrounds)?

When I don’t use AirPlay, audio does not go to my surrounds :-/. So if I do stream using AirPlay should I be getting Atmos sound (assuming the content is Atmos of course)?

Help! My TV is LG oled65cx (2020), I'm connecting to the Sonos arc using the cable that came with the soundbar. I've checked all the boxes: eARC turned on etc, Netflix shows Atmos for the show, but when I start it out flashes "Dolby vision" and the Sonos app says Dolby digital plus 5.1. What can I possibly be doing wrong? I have unplugged the hdmi and power chords on both devices while switching to internal speakers in different orders but to no avail. Help?

What Blu ray player are you using? Should I consider a used Samsung k8500 to decode dts to Dolby digital and will it still deliver atmos?
