Arc doesn't work with Samsung TV Q95T : If you want Dolby Atmos avoid Samsung Flagship TV's

I bought a New Samsung TV and Sonos ARC Soundbar last week: 

Samsung TV Model QE65Q95TATXXU

Software Version : 1115.5

Connected Sonos Arc to the eARC port 3 on the TV and the Arc only delivers any sound when the eARC is switched off (no Sound on Automatic). The Sound output on the TV is only recognising the ARC as connected to HDMI when it should recognise it as connected to the eARC HDMI port. The Dolby ATMOS compatibility button makes no difference when on or off. Pass through setting makes no difference. Dolby Atmos (DD+) is recognised by the SONOS App when playing directly from Netfix App on TV, this means the TV and SONOS ARC are not talking to each other and not recognising the eARC signal (it should say DOLBY Atmos not DOLBY Atmos DD+). Checked all connections and have rebooted both TV and Soundbar with no success

Not ideal when the TV and Sound Bar cost over £3500, I just want it to work and thats what should be delivered by SONOS.

Spoke to SONOS Support (Xander P) and these are the quotes from him:

It does look like there may be some issues arising when the eARC function on the TV is enabled. DD+ is capable of carrying a compressed ATMOS signal, so you should still be able to experience ATMOS from your Arc. In the mean time however there's no fix for this.

I'm not able to give you a solid answer right now unfortunately, however the Arc is known to work with other TVs so my inclination would be that this is a Samsung issue. We are certainly aware of this however and we are reaching out to Samsung in order to get this resolved.

I would expect this to be fixable via a Firmware update, however I can't guarantee this unfortunately.

We are reaching out to Samsung in order to get this issue resolved. Due to the huge number of TV models and manufacturers, issues such as this do sometimes arise - in any case we are looking in to getting it resolved and we are happy to assist any customers which are affected by this issue.

So basically SONOS are blaming Samsung because the ARC works with other TV's. No firm promise of a fix, not very impressed with SONOS at this point as Samsung could be classed as a major supplier of global premium TV's and you would have thought that SONOS would have ensured their premium soundbar would work with the new Samsung Flagship range, but apparently not.

Suggest SONOS and Samsung get their act together and sort out the issue.

@106rallye The linear setting works fine and does give surround sound yes, however there does seem to be a difference in sound quality and “immersion” when the “Dolby” setting in enabled, which sounds better than the linear mode, however with “Dolby” I get the delay in sound vs. video… I have my PS4 connected to the one-connect box, so the sound is sent via there to the Sonos system. (DTS i know is not supported) Not sure how i can get lip-sync working properly when using “Dolby” setting

 

I agree with your comment on the one-connect box. it appears that is indeed where the problem lies unfortunately… I just raised the issue with Samsung support here in Holland, and they said they will send me a new One-connect box straight away. I told them I don’t think that will change the issue, but they want to try it anyway. Guess it’s never a bad thing having a spare one-connect box given they are crazy expensive haha. Still doesn’t fix the issue though :(

Just has a response from the Presidents Office at Samsung stating “our AV team has advised that they are indeed in contact with Sonos and awaiting response from their technical team. As soon as a response is received from them, I will be in touch with you. “

So Both sides are definitely aware and need to work together - come on Sonos!

Why wasn’t this resolved before the Arc launch? Sonos must have tested a bunch of combinations, and should have notified the other manufacturers of issues and worked with them to have the fixes ready for launch.

This is common practice in the AV space, especially for complicated items like HDMI interop.

Got the same here CvH7.  Brand new Q95T 75” delivered this afternoon.  If I leave the TV on eARC off, I see Dolby Atmos for some Netflix and Amazon Prime app movies, and some that say they are Atmos just say Dolby Digital 5.1 in the Sonos app info  If I enable eARC I get no sound on anything anywhere.

I’m hoping this will be resolved in the next 27 days (return period).  If not, I’m not sure what Samsung will offer or do. It was an expensive TV here in the UK.
