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.

    Hi, I just purchased the Samsung Neo QLED 4K 55QN95A with Sonos Arc. After reading all the compatibility issues between Samsung and Sonos I was surprised that I didn’t have the sound issue...at first. Now I seem to have intermittent drop outs in the sound. Power cycling the Arc doesn’t work. Only power cycling the Samsung TV. Furthermore, I see that the Samsung TV is continually swapping between the HDMI eARC (Sonos) and the TV sound output. It seems that the TV is trying to play through the Arc but no sound is playing so it swaps back to the TV speakers for a few seconds and then tries again. This issue has been going for a few years according to the forum posts and there is still no fix.

    I got the HD Fury Arcana for my old Samsung KS8000 with the Sonos Arc and it plays what it should in Atmos and other sources. I’m just waiting on delivery of the Q95T so hoped I could remove the need for the Arcana. Guess not for now. Those that are suffering with lip sync issues or not getting Atmos could try the Arcana.
