Dolby Atmos with Sonos Arc and 2020 Samsung QLED (Q80T)


I recently purchased a new Samsung (2020) Q80T (Q8DT- Costco) Series - 4K UHD QLED LCD TV and also purchased the Sonos Arc. I have connected the Sonos Arc via HDMI to the back of the TV (HDMI-3 (eARC-Port)). 

 

In the Expert Sound Settings on the Samsung TV I have enabled:

HDMI-eARC Mode to Auto**

Digital Output Audio Format to Auto

Dolby Atmos Compatibility (selected and on)

 

I then go to Disney+, Apple TV+ or Amazon Prime on the native apps provided on the Samsung TV and chose a movie with Dolby Atmos listed in details. Once the movie plays I go to the “about my system” on the new Sonos S2 app and select the Sonos Arc to verify the audio output codec. **It displays the Audio In as Dolby Digital Plus 5.1 when HDMI e-ARC is set to “OFF” in the Samsung TV Expert Sound Settings and Dolby Multi Channel PCM 5.1 when HDMI e-ARC is set to “AUTO”. I do not have the Netflix UHD 4k plan at this time so I have not trialed this with Netflix. 

 

I have never been able to get the Sonos Arc to display Dolby Atmos on the now playing screen or about my system in the app despite multiple attempts at changing the settings.

 

Note, I’m not streaming from an external device (Apple TV/Roku/Firestick etc), I’m simply using the native apps provided by Samsung which include Netflix, Apple TV+, Disney +, Prime...Additionally, aside from the Sonos Arc I have no other devices plugged into the TV. My TV is connected to my personal 5gHz WiFi and I’ve got decent speeds (30 mbps download and 25 mbps upload).

 

I can't understand why the Sonos Arc won't play Dolby Atmos. Is it a streaming issue - are the native apps not supporting the output? Is it my internet speeds? My picture seems great though. Also why does the codec change when the HDMI e-ARC is changed from Auto to Off. I would really love to be able to get Dolby Atmos sound coming from the Sonos Arc. Any help or guidance would be really appreciated. Thank you.

Has anyone had any luck getting the native Disney+ and Apple+ apps to put out Dolby Atmos yet? I see it working for Prime but no luck on those two. I have the Samsung Q80T and Sonos Arc. If the Samsung seems problematic, does anyone have experience with the native apps on the Sony XBR 90CH? I hate the idea that I spent this much on a flagship TV only to have to spend another $100 for an external device like Apple TV to get the right sound output I also paid premium for. Thanks! 


Atmos 100% works for me using Netflix, Disney plus and Apple TV native apps on my LG C9. So I'd hazard a guess if it's defaulting to 5.1 even though the content you are watching has Atmos (the Atmos logo appears on the movie listing etc) the problem is with the TV not able to do pass through 

according to rtings that q80t should be able to do Atmos pass through over eARC, make sure your RV is on the latest firmware and copy the audio settings from rtings https://www.rtings.com/tv/reviews/samsung/q80-q80t-qled

I have not been able to get the Native apps to work, but an Amazon Fire Stick 4K is my current workaround and if you keep an eye out for deals you can get them for $20 or so … not ideal, but not too frustrating either.

This may already noted/answered. I have the same TV and an Arc. I had to update my Netflix subscription because only the Premium plan allows for Atmos streaming.

 

 

It's my understanding that samsung tvs in general, including the newest flagship models don't support dolby atmos fullstop, Samsung don't beleive in it, they don't believe their tvs need it. 

The lip sync is definitely an issue but I was able to fix that by going to the Samsung expert settings and taking the audio delay to zero (I believe it’s set to set to 80 or 100) at baseline. Then you can change the lip sync delay in the native Sonos app (system - select your device - tv dialogue sync). Once I got rid of the audio delay on the Samsung my lip sync wasn’t an issue anymore. 
 

Ultimately I was able to get Dolby Atmos to display with the Netflix app but Disney + and Prime still do not display atmos. Might just be the native apps on the Samsung TV.

Mostly positive experience here. Received and set up SONOS ARC on Samsung Q8DT. No issues with set up. ATMOS shows on S2 App when using AppleTV 4K box. Haven’t messed much with Sammy Apps. I don’t think the local Disney+ App does ATMOS, while it does through the AppleTV box. I believe the AppleTV 4K self configured for ATMOS when I attached the ARC.

Only irritant, besides slight lip sync issue, is that the ARC does not show volume level numbers. I am on Comcast Cable Xfinity service. A poster there suggested changing the cable box output to Stereo will correct the lip-sync on cable programming. it does !!!! So I think it does appear to be an issue within the Dolby Digital codec that is the lip sync culprit.

Are there any updates on this issue?

I am having noticeable lip sync delay issues with my Hisense Q8(not eARC) and Sonos Arc. Hisense blame Sonos, but I'm about to take the TV back and was going to swap it for a Q80t. Is that wise at this stage? Is the issue only with eARC?

Any help is great

I got it working! So I made 2 mistakes, I first downloaded the Dolby trailer earlier from the official link but used the ‘for mac’ download and it didn’t work on my TV. I then downloaded it from an unofficial site that had lots of trailers and could only get the picture to work. I suddenly thought I should have downloaded the PC files from the official site onto to my USB. I did that and I just had Dolby Atmos activated and confirmed in the Sonos app. Sounds amazing. One thing, my rear speakers are on stands behind my sofa … I’m sure it would sound even better if the speakers were above my head (or if the sofa was more forward, which I can’t do).

I may look into wall mounting the speakers.

My settings are a couple of posts above. Have a look and make sure yours are set the same. 

Yes I copied you hoping it would work. Should Disney plus come out in Atmos? 

I don’t have Disney +.  When I use the Apple TV Plus app I am only able to get DD+ with eArc off or 5.1 Muti Channel PCM with eArc on.

I’m U.K. based and Do not have a one connect box. My arc is plugged direct into the dedicated Arc HDMI port.

I downloaded the Dolby dignity file Amaze In Lossless form and when I try to play it, it says ‘unsupported feature’ … I have the picture but no sound. I have the Arc, sub and surrounds with a new Samsung 55” QLED TV. Any help?  

Do you have a One Connect Box on your TV? If you do then that will be your issue for it not playing. You will have to turn off eArc in your sound settings and then you should get Atmos played via DD+. But it won’t play that trailer you’re wanting to play as it is likely done in True HD which I believe requires eArc.

I don’t have a solution for you. I’m just relaying what I believe is the issue. I live in Canada. Samsung doesn’t provide the One Connect Box  with their sets here. It’s clearly something that Samsung needs to sort out. 

It appears the One Connect Box is the issue with eArc and the Arc. My 2020 Samsung Q80T and Arc are working flawlessly together. 

So what return the TV? I can’t get the HDMI ports on the TV as there is no furniture close to the TV to put all the equipment and its 75 inch!

I have the q95t and I have my Arc wired straight into hdmi 3 (eARC) the Arc only shows the Arc as a HDMI Receiver as opposed to Receiver eARC - I have a horrible audio delay when using Atmos on my Xbox One X and I think a possible fix could be to enable audio pass through on the TV but this is only possible on eARC devices, which for some reason it doesn't seem to think the Arc is. Does your Q80T display the Arc as HDMI receiver or HDMI eARC?

Thanks

Man I had the same issue!!! Same tv same setup spent 6 hours with Samsung support and Sonos support and they blame each other, THERE IS NO FIX! it’s just that the tv doesn’t support eArc other than the Samsung soundbars, they even released an update 2 days ago and it doesn’t fix the issue!! $5k tv and $3k sound system, good job sonos and Samsung

Besides the different Firmware, US vs UK, some have pointed to the One-Connect box as the problem. I assume the Firmware addresses the eARC differently in Built In vs One-Connect.
