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.

My setup is a Samsung Q95T and the Sonos Arc. For some reason my Q95T is only picking up the Arc as a HDMI Receiver despite the fact that the supplied HDMI cable that came with the Arc is plugged directly into my TV's HDMI3 eARC port. 

 

As my TV is unable to pick up the fact that I have the Arc plugged in as an eARC Receiver I cannot enable the option to allow audio pass through, which I believe is causing audio delay.

 

Samsung have told me that the problem does not lie on their end and have advised that there is nothing they could do to fix it themselves, they've just sent me to Sonos

 

I purchased the TV and the Arc together because I was excited about the fact that they would work well via the New HDMI eARC input, experiencing such terrible audio delay isn't really what I expected after spending so much money. If I'm unable to get this fixed I'd rather return the Arc and get my money back.

You’re not alone. Here a LG C9 OLED with Sonos ARC with audio delay. I think it has more to with the tv then the Sonos as the audio is delayed which I think is caused by the tv rather then by processing the audio in the Sonos ARC.

Hi Daryl,

 

I have the same set up and brought both together for eARC functionality. Unfortunately I have the same issues as you.

 

I really hope Sonos can find a fix for this..

@ekwok Are you saying that it all works as it is supposed to for the topic starter as he does have Atmos via DD+ on Netflix - the only way it is possible to get Atmos you are not using a 4k Blu ray?

Is there any firmware update needed for the TV?Have you also asked Samsung for help? What did they say?

@106rallye Yes, that’s right.

I read that streaming services stream lossy DD+ Dolby Atmos only.

To get lossless Dolby Atmos, we need bluray and eARC or Arcana.

Having said that, it seems the new Samsung has some bugs there. The need to turn off eARC for any sound to come through is not right.

Hi, I've got the same TV as you and I'm having the exact same problems - It's all well and good that Sonos is saying the difference we are missing out on is negligible however when I use my Arc with my Xbox One X I have a horrible audio delay, which i believe i could fix if i set the TV audio to Pass Through mode - Unfortunately this is only a feature available through eARC mode which we're unable to use! I've been in touch with Samsung a few times about this issue and they just keep sending me back to Sonos claiming that as far as they can tell there are no issues on their end.
