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

Unfortunately, although the Frame has eARC, it has the same problem as the Q95T. The best theory to date is that all Samsung 2020 models with the one connect box (which includes the Frame)are effected.

I am pleased to say that after reading CvH7 helpful comment and downloading the Samsung TV update, I disconnected the optical cable, plugged in the hdmi cable to e-arc and voila it works! No lip sync issues with Sky Q and sound works well on Netflix etc. Thanks all!

According to this thread on Samsung’s support site, they are working on a fix. Recommend people chime-in there as well: https://eu.community.samsung.com/t5/tv/potential-major-issue-with-2020-samsung-tv-s-with-one-connect/td-p/1857527/page/2

Samsung has an updated posted as of today! My TV (Frame 75”) wouldn’t auto download so I manually downloaded and installed on a flash drive. Everything appears to be working as expected eARC auto is turned on and working!!

btollenaar, could you please check what is the firmware version you have now on your TV?
My Frame 55” does not have an update on Samsung’s site, just the same v1304 from August.

It’s listed as 1402 - released on 9/29.

I had to manually download it on to a flash drive and update it from that.

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 have a new Samsung Neo QLED: QE65QN95A. I have tried just about anything and Sonos technical support has given up on it claiming that the Sonos Arc is working as designed and intended.
I get audio cutting from anything connected with HDMI (PCM audio works fine).
I have almost given up.. But here is my forum thread on the issue.

I have been having the same issue with Q95T and ARC connected to hdmi 3 e-arc. I just spoke with Samsung support and they asked me to under General> external device manage > input signal plus> enable the blue dot on all hdmi sources.

this resolved the issue now the sound works fine with e-arc enabled and atmos compatibility enabled.

I hope this works for you all.

Thanks for sharing this @Goofy87
As it is the first comment I see in cyberspace that implies a solved issue I would really appreciated some more details.

Did it’s stand time (Still no issues since fix)
What’s your setup, external input like appleTV or only built-in apps?

There are great deals on the 75” Q95 right now but I can’t really justify it with an ongoing issue like this.

Hi CarlChrister,

There are still intermittent issues unfortunately but the fix is fairly easily normal when it happens, toggeling on and off on the e-arc setup. Or worst case restarting the TV by unplugging power, no great for such an expensive setup but it's my life now.

But just a suggestion if you are looking to get a new Samsung why wouldn't you wait for a price drop on the Neo-led models as they have 4x e-arc connections and it's seems to have non of these e-arc issues on the Q95T, I would if I had the choice at the moment.

Not quite know about TV but I think LG is quite okay. :)

Forgot to mention:

Make sure you perform a reset of the hdmi sources after activating the input signal plus on all hdmi ports:

unplug all hdmi cables from one connect. Afterwards unplug power cable from the box for 30 seconds. First reconnect the hdmi cables then power cable. Hold power button on the remote for 10 seconds and the tv will start with checking all the sources.

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.

Have you resolved this issue? Does this issue happen for tv via sky tv ?

Yes still have the same problem, have to use optical cable and yes it does happen for Sky Q tv with lip sync issues

Hi Guys,

i’m looking to buy the Samsung Q95T but after reading all these comments, i’m not sure if the issues have been resolved. I will be using Sky Q, a 4k Bluray, Firestick, etc. Any ideas?

best

John
