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

@CvH7 im not sure about your research, but if I go into expert audio settings on the TV it has the option to turn eArc to auto 🤣🤷‍♂️.    Let’s hope the new arcs shipping in November have fixed the issue once and for all! 

I’m sorry to report I don’t think it’s completely fixed. I have a 65 inch The Frame and a new ARC. It did work out of the box for a few days but then suddenly I had the intermittent audio. To make a long story short I turned off e-Arc and that worked for a day. The following day the problem was back so I reset and reconfigured the ARC and now everything is working again. Not sure what cause the system to become intermittent. One thing I noticed is the Samsung would show HDMI e-Arc, then  just HDMI when the problem was occurring. 

Hopefully this was a transient issue. I’ll report back if it comes back.

I have same issue , after the last auto update on the Samsung tv 1403.1 its an issue again for me. So a sulation for you Was to reset Sonos Arc ?

Hi, I experience the same issue with my 2020 75” The Frame. Whenever I switch TV on, I experience the intermittent sound issue. I have found setting e-arc to auto and disabling Dolby Atmos Compatibility, and then getting back to the previous configuration fixes the issue without having to unplug Sonos Arc.

I hope this is fixed soon since it is annoying having to be changing config so frequently

I have a 2020 Q80T, Arc, Sub Gen 2 and a pair of One SL’s. I have the Arc plugged into eArc, Atmos enabled in the TV and the TV set to eArc. No lip sync issues at all. The Sonos app indicates Atmos when playing Atmos content. If I turn off eArc in my sound settings the app indicates Atmos Dolby Digital+. 
my set up sounds great and has worked flawlessly so far. The TV is 10 days old. 

Thanks for your feedback Alberta, Can you confirm please that the eARC setiing is on AUTO. So Sound > Expert Setting > eARC enabled option is Auto. And then confirm you have sound. Can you confirm the source of Atmos please and also can you confirm when eARC is enabled if you get any sound on normal channels such as terrestrial broadcasting/in built apps such as Netflix?

Had dd+, but followed the settings as stated above. On my Samsung tv I hit settings>sound>expert settings>eARC enabled option is auto. Now when I check my system and main page audio output, I’m receiving true Dolby Atmos….no more Dolby digital +. Hope this helps others if you have a Samsung tv.

I have just been on the phone with Sonos and on chat with Samsung at the same time. Sonos believe the issue is the way Samsung has implemented the eARC in the TV is not to HDMI standard. They are still actively working on a solution with Samsung,

Samsung and sonos have advised to turn off eARC for the time being until a fix is issued… (fix might be returning this tv...) D̶o̶l̶b̶y̶ ̶A̶t̶m̶o̶s̶

FYI Just got off the phone with Samsung and she sent me a link to download a new firmware update Version 1460.9. It’s not available through the TV’s automatic updates. You have to download the file.

 

This is from Samsung Tech support: This is the link of the website where you can download the latest software version of your Samsung Smart TV https://www.samsung.com/us/support/owners/product/qled-tv-q6dt-2020. After the download , extract and unzip the files then plug the USB at the back of the TV (usb port).

 

I just installed it and now the TV shows Sonos Arc Receiver as the output whereas before it would just show eARC.  Hopefully this resolves the issue we’ve all been having. Good luck to everyone.

I have just taken delivery of the Samsung Q95T 75” and connected it to the ARC. I have had no issues so far with Dolby Atmos or any other format! Perhaps it has been fixed?? or am I just lucky. :)
