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

I think that Samsung has different firmware for UK/US. The plot thickens..

I was thinking the same thing. Perhaps we have different software configurations. I feel fortunate having read the issues many have had with Samsung and Arc functionality. I bought the TV knowing there were people having issues but I’ve always been a Samsung fan. This is my first Sonos experience. Started with Arc and quickly added the Sub and Ones. Not because the Arc wasn’t getting the job done but after listening to the Arc in a full 5.1.2 set up I just felt I would take the plunge for max enjoyment.

All - reponse from the CEO’s office of Samsung as follows:

“I am contacting in response to your recent communication received to the CEO of Samsung UK. I am sorry to learn of the challenges you have faced with connection of your Samsung television and Sonos sound bar.

 

While our department is not technically trained, following receipt of your email I have reached out to our AV head technicians to request their comment. They have reviewed your concerns and note that the response you have received from Sonos appears to be that they are aware of this issue and are investigating, while regrettably not having a timescale for solution. Our AV department has given assurance that this issue has not been reported by customers using Samsung sound bars with this television, and so trust that Sonos will continue to investigate and take steps to improve their product compatibility.

 

We appreciate you taking the time to raise this with us, and while our AV department have taken your comments under review, as above this does not appear to be an issue affecting compatibility through Samsung devices. “

 

So the ball is with Sonos - can someone from Sonos acknowledge this please as an issue?

“....Our AV department has given assurance that this issue has not been reported by customers using Samsung sound bars with this television...”

The reply is telling you that Samsung TV and Samsung sound bar = no problem. 

Indirectly telling you to buy Samsung products. 

I would suggest you change out of Samsung TV.

Here are my sound settings on my Q80T 2020 Samsung.

To my understanding, the Q80T model does not have an one connect box. Please confirm. If so, the above would indicate that the problem lies with the one connect box. TVs without the box works with eArc, TV with the box does not. This has also been suggested by other users.

I have the Frame (which has an one connect box) and cannot pass sound through eArc.

I don’t care for that answer either.  The eARC standard means that it should work with any eARC capable audio equipment, not other Samsung products.  I would want Samsung to confirm that their products are following the standard correctly.  

I am more inclined to believe that Sonos is using the standard correctly, because it has shown to work with other eARC capable TVs, and because they don’t sell a video display they would prefer you use.

Honestly though, based on the very mixed results with TVs processing ARC and eARC correctly, I’m not inclined to think trusting TVs to process audio correctly is a good idea.  Although AVRs, who’s main job is audio, do seem to have a better track record with processing video, you still are allowing your audio equipment to limit your video capabilities.

I like the idea of using HD Fury’s Arcana or other options for HDMI switching as well as sending video to display devices and audio to audio devices with no pass through functionality required.   You can buy a display device solely based on it’s display capabilities and an  audio device solely based on it’s audio capabilities.

That might be the reason why you are not getting sounds because you don't have eARC content.

I am playing uncompressed 4k blu rays and there is no sound

I already confirmed this from our product specialist and was advised that this is normal with the TV if you are not using an eARC content.

no, that is wromg

As I've mentioned to you the eARC supports 8k, not the normal 4k.

‎4‎:‎44‎ ‎PM

Recieved Message

It will only work if you have eARC content.

‎4‎:‎45‎ ‎PM

wrong again, it supports both 4k and 8k, its not a video issue its audio. Do you know what eARC stands for?Enhanced Audio Return Channel.

Can't believe you don't know this?

I already coordinated with our product specialist about this, and I was advised that this is supporting 8k.

HDMI 2.1 supports 8k and 4k at high frame rates. eARC supports uncompressed audio. Hope this clarifies.

‎4‎:‎50‎ ‎PM

Recieved Message

Let me coordinate with this again, please hold on.

‎4‎:‎52‎ ‎PM

Recieved Message

I already checked this again and as I've mentioned to you the content that you are using is not eARC content. That is why it is not working.

‎4‎:‎56‎ ‎PM

Recieved Message

I haven't heard from you for a couple of minutes, I just want to check if you're still there?

‎4‎:‎59‎ ‎PM

sorry, I know this is wrong. The soundbar should emit sound either compressed or uncompressed when eARC is set to auto. If standard tv is played, you will receive sound, it sound from an uncompressed source is played it will also be passed through. As I have explained, I have played sound form all sources including Dolby Tru HD which is uncompressed sound that eARC can handle and no sound. I am afraid you are wrong in your statement. In your view then, what is eARC content?

Can a product specialist contact me?

‎5‎:‎01‎ ‎PM

Recieved Message

We cannot be able to do that because we are not allowed to transfer customers to another representative including our product specialist.
