Question

Sonos Arc and Samsung Q900 Dolby Atmos Support

Will my TV (QN65Q900RBFXZA) allow for Dolby Atmos audio using the OneConnect ARC port? I just ordered the Sonos Arc which supports Dolby Atmos but not sure if my TV is going to become the issue.

I've been reading Samsung hasn't released an update for eARC capability. Honestly, I am not sure what the differences between ARC vs. eARC and if it will be an issue.

I said external devices and they do not use DD+ they use higher quality codecs such as Dolby true HD, DTS etc. external streaming devices such as Apple TV 4K also don’t all use DD+ they use Dolby MAT which the arc does not support, though some tvs can decode this for the arc eg LG

You stated that external device couldn’t replace native Samsung apps, which implies streaming since that’s what Samsung apps do. Streaming sources, internal or external are going to be DD+. My understanding is that that’s even true on ATV for non-Apple apps. According to Sonos, they do support MAT.

Dolby TrueHD and DTS are codecs found on physical media, so therefore those will come through external devices as you stated. However, the statement that anything coming from an external device (HDMI) is going to require an eARC capable TV in order for the Arc to get atmos format audio is incorrect.

I would hesitate before speaking so definitively about the Apple TV. Early reports about Apple TV and the Arc have the majority of folks getting Atmos of some sort. On the main thread, a person just reported getting DD+ w/ Atmos from an Apple TV through his 3 year old LG that only has ARC.

So it would seem the kerfluffle over Apple TV was just a bit overblown.

Slightly changing my words but I see your point. In my case my other streaming device is the Xbox one but this will not recognise the arc as an Atmos device without earc from my tv and unless I’m missing something there is no option for direct connection. So the Xbox downgrades any uhd, game or streaming app to Dolby 5.1, Smart drive above and several articles have pointed to the fact that Apple TV won’t work with a number of tvs as it doesn’t process that codec, so it’s up to the tv to change it to something the arc can read. So what streaming device can I purchase to work through regular HDMI on my tv that will pass Atmos from Disney plus and amazon prime please?

As I said in the bit you quoted it seems only some tvs like LG can decode the Apple TV, this thread is in relation to my Samsung d900 which is what I and other posters have the issue with, I have no major complaints with the Sonos arc; in fact I mostly love it so far; but with this tv it’s functionality is seriously limited

I did some digging and as far as I understand Samsung botched the native apps Atmos support with it’s latest firmware upgrade (for the 2019 line of TVs). So until Samsung fixes this and or also enables eARC with a firmware upgrade or Sonos Arc supports LPCM the Sonos Arc cannot be used to it’s full potential on the Q900R - which this thread is about.

I had to play around a lot to get Netflix working, little trick, go to amazon prime video, play something, go to settings change the audio setting to Dolby digital plus, then go back into Netflix and then some shows had the Atmos logo. Disney doesn’t work and neither does amazon, nor my Xbox etc. basically the native Samsung apps are crap and we can’t get round this using an external device as there is no earc

I’ve got a Samsung Q85R and the Sonos Arc. Also having the same experience. With the TV’s apps Atmos is only working on Netflix (although it has changed itself back to 5.1 a couple of times and have to use that trick to get Atmos back)

Amazon and Disney - just DD+
Apple TV app - just DD

Also have a hard drive plugged into the USB, movies with atmos in DD+ codec are playing fine with ‘lossy’ Atmos (DD+)

Movies with full atmos in TrueHD codec just play in DD, probably because of no eArc

Can’t get Xbox to do Atmos or DD+ and DD still has massive audio delay, so leaving on stereo for now.

Hopefully the supposedly coming soon eArc update for the Samsung QLED’s will sort all of these issues. Although I don’t know why some of the TV’s apps aren’t working fully as that has nothing to do with eArc

I should have read this forum before, got my Sonos Arc today and as most of you have stated above, no Atmos. When I use Apple TV Tidal app to stream Atmos songs, Apple TV shows an error stating it can only output sound in Stereo. I also pre-ordered the HDFury Arcana, hoping that it would fix all issues.

Did the HDFURY Arcana fix all issues?

@jgchiriboga It absolutely did! I was blown away by the simplicity of the device and the way it is able to deliver Dolby Atmos audio stream to the Sonos Arc. I am using the Apple TV 4K connected directly to Arcana. In addition, there is a setting for LLDV > HDR, whereby the Apple TV detects and provides the Dolby Vision option for me on the Apple TV as an option. The image and colors are so much better with this option turned on. If you haven’t purchased it yet, I highly recommend getting it. It also fixed any previous lip-sync issues that were apparent on streaming channels.

Hi,

I have a Samsung tv too, Ks 8000 which will not pass through DD+ either and am about to buy an Arc. I have various external sources such as Apple TV, PS4 and soon ps5. Would the Arcana simply sit between my current Arc out from my tv and the arc in on the Sonos ARC? All sources would still connect to the Samsung one connect box? Thanks.
