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

I have spoken to Samsung, Sonos and Best Buy this morning! Samsung said they have no current complaints on this issue. Sonos has said there is a known issue and their engineering teams are working on a fix but eta on update is unknown. They also said Samsung is the only brand which has a known issue to the HDMI ARC compatibility. Who knows if this will take another few months or weeks but I have a difficult decision to make either to return this Q80T and go with Sony Or take a leap of faith! 
 

any advice?

Having looked through the comments, let me contribute a little bit.

 

Set Up

  • 2020 55" Q95T (QE55Q95TATXXU)
  • Sonos Arc + Sub (gen 3) + 2 ones

Issue

I confirm that I face exactly the same issue as the one observed by Mike. 

In particular, once you enable the eARC you get no sound, while once you turn it off, you get sound output but up to 5.1 surround level and not the desired Atmos.

I am not sure that it will get resolved, but I guess I can hope for a solution by both Samsung and Sonos.

I spent a few hours this morning with Samsung and Sonos and I now have eARC auto enabled on my Sonos ARC (only speaker I have connected) working. Sonos was able to check on their end that it was connected and working as expected. It involved a lot of resetting, unplugging, plugging back in, rebooting. It is my belief that other inputs where interfering with its initial setup.

 

Try this: unplug everything from the Samsung One Connect box but the Sonos ARC. Select Reset on the Samsung TV (sucks you lose all saved settings). Boot up everything, enable eARC Auto, once enabled unplug the TV for 30 seconds and then plug it back in. This worked for me. I was then able to plug in all my other input devices, at this point the Sonos ARC stopped working (happened when I plugged in a Nintendo Switch) when that happened I unplugged the TV again for 30 seconds, plugged it back in and all is well with the world, beautiful Dolby Atmos (uncompressed) sound.

 

Let me know if this helps anyone else out.

I will follow up an a few more phone calls and have found out the following:

Sonos has been diligently working on a fix for nearly 4 months. The issue from what I have gathered is the Q Symphony technology which is new and is not working properly with Samsung TV’s. IT is the only known brand to have issues facing the Sonos compatibility. Sonos said that it would be idiotic to not fix this problem because Samsung is #1 selling brand in the world and we need to sell our products. 

I spoke to tech from Best Buy, to figure out what to do with my brand new 2 days old 75” Q80T. An expert said that if your not planning on upgrading to Sonos in the next 6 months you should be fine however the Q80T is best quality versus Sony X950 or X900. I am taking a leap of faith that Sonos and Samsung find a fix quickly, I am hesitant to keep this unit and unsure what to do before my return window closes. Why have an expensive TV if you can not enjoy its features?

Ya, the auto eARC setting didn’t ‘hold’ audio eventually just cut off, had to turn auto eARC off … waiting for a proper fix...

I have had a samsung technician attend my home to look at the same issue. When i choose AUTO the Sonos ARC mutes.. no sound! Also, when i turn my 2020 75” Samsung frame on the Sonos ARC sound cuts in and out. I have to unplug and reset it, once i have done that is it OK. 

 

I also took my Sonos ARC and tested it on a 2020 SONY And LG  TV and had no problems at all. 

 

Samsung tested a new samsung Soundbar with ATMOS and it worked fine.

 

Samsung and  SONOS are blaming each other. Doesn’t really help the consumer.

I have read this thread on the Samsung TV and I am in the same situation. The Sonos Tech after several jours of trouble shooting said and I quote” upon checking both diags, the TV logs are still showing something that is not normal in the TV processor, here is the message: Input Format change Dolby MAT (2.0.0) --> Dolby MAT
(5.1.0) so basically the TV processor is constantly changing the audio format and it can cause some issues with the audio.”

 

I purchased it at  Best Buy and I am replacing the  TV with an LG OLED.   I have no reason to not believe the Sonos Rep

I have received an e-mail from Samsung to advise Sonos and Samsung are working on this issue and should have an update mid September.
