Sonos Arc Samsung Frame TV eARC not working

Hi All,

I got it to work and it’s been working the last few hours.  I unplugged the soundbar from the Frame and then switched to eARC Auto.  Once switched to Auto, I then plugged the Arc back into the OneConnect box and it’s been working for a whole movie.  Only time will tell if it continues to work..

I have the same issue with Arc connected to Samsung Frame 2020 and eArc (Auto) -> no sound.

But having switched Samsung eArc to off - format to auto - dolby-atmos to on -

i get dolby atmos sound (also dolby atmos logo on S2 app) while playing e.g Jack Ryan UHD/dolby atmos via amazon prime app.

Same issue here with Frame 2020 and Sonos arc. I get Dolby atmos but only when earc setting is OFF on TV. 

I’m seeing what seems to be similar issues on the Q90T and I posted here:

Other Samsung TV owners are saying the same thing. Hard to believe, given Samsung TVs are very widely used, that this is purely a Samsung issue.  How do we get more eyes on this? Until I see Ryan S responds, not sure if Sonos is noticing this.

Given that it’s only on Samsung, and not any other brand TV’s , it’s hard to conceive of it not being a Samsung issue. 

I can’t speak to other TVs working or not but I am suggesting it could be a combination of the two (having done standards work before, subtle interpretations of specs by two parties can compound issues when they come together).   

But true, it could purely be a Samsung issue. They are definitely newer to eARC compared to say LG.

Regardless, hopefully Sonos can take a look and verify (and hopefully Samsung can too).

I’m also experiencing what I believe to be connection issues between the Sonos Arc and a 2020 model Samsung Frame 55”.

I’ve spent considerable time speaking to both Sonos and Samsung support and neither have been particularly helpful. The Samsung support in particular has been a criminal waste of time, as the only thing they know how to suggest is that you turn off/on or “factory reset” your TV.

After much trial and error the only way I found I could get the TV/Arc to “connect” was by power cycling both the TV and Arc.

However I’ve recently noticed that if I have the TV on, then switch to play music on the Arc, I am unable to toggle the Arc back to playing the TV sound again unless I again power cycle both the TV & Arc.

I never had this problem in the past with an older model Sony TV, optical connection and the Sonos Playbar.

I’m not sure if this is an eArc issue, a Samsung issue, a Sonos issue or a V2 App issue, but it is a huge functionality regression.

**Edit** - Now I’m struggling to replicate this, I experienced it organically a couple of times over the weekend but in typical fashion I couldn’t replicate when I called support. I’ll keep an eye on it.

same issue on ARC & Q95T.

I have noticed two things:-

1) As noted during the issue, I have always lost the Sonos signal from the EARC source. I.e. I don't see the Sonos picture anymore, if I change to the Sonos source.

2) a quick unplug and replug of the HDMI cable from the ARC fixes the issue.

Might be worth checking these two issues/fixes to confirm same issue?

Same thing with EARC, but if I set to off, I still get Atmos and all works okay, until the above issue occurs every few days.

Same issue on my 55 frame tv 

Sonos - Can we get a comment on this.  I want to purchase a new Samsung q90 TV with a new ARC but not if they won’t work together!
