Sonos Arc and Samsung - eARC compatibility issues

Hi All

I wanted to make you aware of an experience I am having with both Sonos and Samsung. I am on my second Samsung tv (replacement q95t) and the following letter to CEO’s of both companies should explain. Be interesting to know if any members of this community are aware or have experienced these issues.

Dear Patrick/Sang Ho Jo gwi-ha

 

Apologies for the direct approach, however I must make you aware of a situation with regards to two of your companies top consumer products.   I have been a loyal purchaser of both Samsung and Sonos products for a number of years now, and most recently have purchased your Sonos Arc Soundbar and Samsung Q95T television products.   On receipt of these products, I have noticed a compatibility issue between the two aforementioned products around the eARC connectivity. Simply put, once eARC is enabled on the Samsung device, no sound is transmitted via the Sonos Arc. Once Disabled however, sound is apparent.   From a samsung perspective, I have been issued a second device which has had the same issue, and no further known resolution to fix has been offered with technical advising its not a Samsung issue. From a Sonos Perspective, the response from technical has been to "confirm that the issue you are experiencing has been raised with the right teams who are looking into it, regarding e-ARC needing to be off to get audio from this TV. We don't have a timescale on a resolution at this time".   From a loyal user, this is far from perfect with no eta to fix, or even a guarantee that it will be fixed and no clear view on where the issue resides, with Samsung or Sonos?   On looking at the Samsung forums, this appears to be an issue not just for myself but for many other users now. The following is one example of feedback from Sonos on the Samsung Forums:  

"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, you would have thought that they would have ensured their premium soundbar would work with the new Samsung Flagship range, but apparently not."   So my ask is simple - please can your organisations work together to resolve this issue as opposed to the blame culture that has been our experience - Many users have purchased both devices on the strength of this eARC capability, and this is clearly advertised as a function of your devices.  My retailer in the UK is on standby to take these products back if we can't get to a resolution which would be a major disappointment so I hope you can find a solution to this issue for me.   Kind Regards   Mike

Also have the q8dt and arc with install slotted for Monday.  Subscribing to this thread and will share my experiences/settings/connections with everyone.  Sonos has a good track record of fixing things so I guess we will see.  Frustrating to spend this amount of money and have these type of issues!

I just received my SONOS ARC and set it up with my SAMSUNG Q8DT. No issues with the set up. The TV recognized the ARC and turned on all the appropriate settings, e.g., ATMOS to AUTO, etc. When playing ATMOS content, the S2 app shows Dolby ATMOS. My AppleTV 4K also recognized the ARC and   configured itself for ATMOS content.

One minor complaint, hugely reported, is that the ARC does not have Volume Level numbers, only a + at the top and a - at the bottom of the field when you raise or lower volume. Most think it is a pure lazy, minimal effort, setup by the SONOS people.

I do still have a minimal lip-sync issue. I have Comcast Cable and someone on that forum, I believe, posted this advice:

 

The lip sync issue is there...just enough to notice it. I stumbled across a post somewhere, possibly the Comcast Xfinity forum, where a poster had traced his sync issue to the Dolby implementation. He suggested that setting the Xfinity Cable box to “Stereo” (which I believe is PCM) instead of DD 5.1 fixes the sync on cable programming. Viola ! It does. Since most of my watching is cable fare, this is a decent solution for me until someone engineers a Dolby fix.

Hi Everyone, hope you get the Samsung fix, I swapped out the Q95T for an LG GX and its better in every way and eARC works with the ARC. Movies on Apple TV are now streaming in Dolby Vision and Dolby Atmos and TRU Hd Blu Ray is uncompressed.

This sounds like an issue with one connect, and again hope this is rectified.

My q8dt with arc isn’t getting atmos according to the app.  Any ideas?  I have all the same settings as mentioned in this thread.  Tried with 4K Apple TV on input 1 and also through the native apps and not getting it.  Shows Dolby multi channel pcm 5.1.  Arc is in input 3.  Did everyone use the hdmi cable that came with the arc?

And of course I ended up rebooting everything this morning and can now play atmos streaming from the Apple 4K.  Not going to bother with the native apps for now.  Sounds awesome!

@BBH , question for you … so are you seeing any dropout of sound at all? And if not, are you set to auto eARC?

I am set to Auto and I don’t notice any dropouts at all. I added a SONOS AMP to “fold in” my existing in ceiling speakers as Surrounds. All sounds good to me.

Hi Everyone. After reading through the various posts I still don’t see there being a resolution to the problem. We recently bought a Samsung Q80T bundled with the Sonos Arc and Sub (Gen3). Everything worked great till just recently: We are suddenly experiencing sound cutting in and out. I stress that everything was fine for weeks and the problem suddenly started for no apparent reason? Nothing has been changed in terms of system settings, connections, etc.

When the problem occurs disconnecting the Arc from the TV fixes the problem for a short time. Alternatively powering down the Arc and starting it back up fixes the problem for a short time. 

Otherwise sound from the TV speakers works fine and there is no sound outage. It is sound from the Arc that seems to be the problem.

My concern relates to the fact things were fine to begin with and the problem suddenly started for no apparent reason? If we were to change TV we may be in the same situation where the Arc works well in the beginning but then suddenly is plagued by gremlins. In the meantime there are reports of problems with other Arc+TV combinations. Hence the one common denominator seems to be the Arc.

Interesting. For me, though I got my Arc early (so not from the latest manufacturing location), what I see is almost like clock work, every 25 to 30 minutes the sound cuts out for a split second. It use to be less predictable but much much more frequent, but after various firmware updates (on the TV, a Q90T, and the Arc) as well as a reboot of the Arc and the TV I’m now in this clockwork like state.

It is exceptionally odd. Most of my watching, however, is from an Xbox One (and I have tried and Xbox One S and Xbox One X, both have this clockwork like behaviour).

Has this issue been fixed? I just purchased Q80T THIS PAST WEEKEND! I am concerned that upgrading my SONOS playbar to ARC will resort in the same issue you are all facing. Is this a world wide issue or isolated to UK? Are customer in USA finding same issue with Q80T and Sonos Arc compatibly? 
 

Any help appreciated? I spoke to Samsung tech and they say they have no complaints so far on this issue? They are not aware of an issue. They also said the most recent firmware on Q80T is 1301 August 4, 2020! I am tempted to return the TV if I can not use Sonos ARC with the Q80T
 

thank you..
