Sonos Arc Samsung Frame TV eARC not working

I’m on the latest firmware 1402.7 (I’m in Australia) and I have eARC working on Auto now, Dolby Atmos is working. Unfortunately, I also have the cutting in and out issues when turning on the Q95T TV and ARC from standby. But it doesn't happen everytime I turn on the TV, it’s random, so I don’t know what going on. 

Installed the 1402 update with an USB disk! Searching online didn’t work so far when trying it out on Friday! After little 15 minutes for downloading, extracting the EXE file to USB and updating the TV I made it without any issues. 

Reconfigured audio settings to enable eARC option on my Samsung Frame and all works well for the last couple of days. Both Sonos and Samsung made the updates available. Thank you for that! For me I had the struggle for little 4 weeks and with both premium brands I am satisficed with provided results so far.

I made my wife also happy by configuring an alarm with her favorite radio station as Google Assistant  ignored her command :) and doesn’t want to play requested radio station. I am happy Sonos customer from the Netherlands 👌. The only thing pending at my to-do’s is to get real Dolby Atomos content and experience that with this Sonos Arc beast.

Watched a movie with Dolby Atmos, the movie went for 1 ½ hours and I had 3 audio drop outs that lasted for about 2-3 seconds each time. For what you pay for this A/V combination it’s pretty disappointing, these problems need to get sorted. I’m the latest firmware with both the TV and Arc. 

Here are my findings after having updated the Q80T, Apple TV 4K and Sonos firmware:

Lip syncing issues only fixed by:

• TV set to E-arc Auto
• Delay to zero on Sky Q, Q80T and Apple TV 4K
• Q80T set to passthrough and Atmos compatibility on

The next day (with no changes to setup) the sound kept cutting out, the only fix for me was to unplug the Arc and plug back in again, no lip syncing problems again and this has only happened once so far.

I've not yet experienced Atmos via SKY Q (shown in Sonos App when output)

Neither via the Apple TV app on Q80T, but I get Atmos using my physical Apple TV 4K

Also watching a Atmos video on YouTube does not output Atmos via the Q80T or Apple TV 4K youtube app?

Alexa very sensitive on the Arc, often overtaking Alexa in another room.

Grouping all downstairs Sonos speakers when listening to radio and switching the TV on automatically unpairs the Arc and Sub and reverts to outputting the source sound which works well.

Last weekend I (living in the Netherlands) received the Sonos Arc and the Samsung Frame 65” (65LS03T). I've updated the Frame firmware with version 1402.6. After this I could use eARC and play movies with Dolby Atmos. 

However, when I turn the TV + Sonos on (after it being of for the night or just few minutes), there is the breaking sounds for a few seconds at a time. Only after a complete poweroff / disconnect the power the sound is back to normal (and then, everything works like a charm). Hope Samsung comes with a few, or even Sonos for that matter - not sure whom to blame :-)  

Just ran the Samsung Update for my 2020 Samsung Frame via USB and it worked great all evening with eARC and verified Dolby Atmos via the app.  Today, I’ve attempted to watch TV and it’s back to the same thing - cutting in and out and often times no sound at all.

This nearly 4 month incompatibility between Sonos’ flagship product and a highly popular Samsung TV line is completely unacceptable. 

@Ditte - are we being heard and what is being done about this??

I totally agree, it is unacceptable. Sonos stated 4 months ago they were working on this with Samsung and nothing yet. Do I send my Sonos Arc back?

As of now my combination Frame (2020) and ARC is working. I disconnected all HDMI devices. Then removed power cable from power Plug for about 15min. After restarting TV, I‘ve disabled Dolby Atmos compatibility.

On next day Sound was still good. Dolby Atmos was active by magic again. Connecting all HDMI devices again. Now since three days no cutting issue anymore.

Keeping fingers crossed that it will stay so.

But have to say that I am using „HDMI“ Not eARC activated yet. Would be next step.

Well. 

Samsung has sent out a repair, to replace the Connect One box, the repairman replaced it. And nothing. Sound cuts off from the Arc still. Its off more than on. For me, its got to be a software issue with Samsung. Because when I go into the the Sound input the Samsung Switches off, between Receiver HDMI and Receiver (HDMI-eArc) then the sound comes on when the system system goes back to “HDMI-eArc. The sound is ONLY a problem when attached to the Samsung One Connect. When streaming music through the Arc there is Zero problems.

As for Samsung, this has been an ongoing issue since day one. Samsung pushed and pushed me to “repair” this issue now Im 4 days PAST MY return date. And now im stuck with this TV. Samsung did elevate this issue with their RRRR division, they were supposed to call me today but didnt. Honestly this is my last Samsung product. 
 

Very frustrating. 

Okay. 

So I actually got into contact with a State Side Engineer. He Knows what the problem is, Works for Samsung only with 1 Connect Tv’s, and WE may have figured something out. All of the updates are find and dandy. But they Do not cover, or at least in my case, something. 

I have the most current Updates from Samsung, but I needed to go into About TV, under the settings. There is a something called “Sub-micom Version”. This was not changed in my case, don’t know about others, in the most recent updates. There is a part the number in the “Sub-micom Version”, and towards of the sequence of numbers it was -1005t-. He sent me a Bin file (because im using a Macbook) and he had to from his end log into my TV, and upgrade it to -1006t- . 

This can only be done from the inside with an Actual Samsung Application Engineer it seems. My system seems to be Stable now. I don’t get anymore Signal loss (sound dropouts) or changes from HDMI to HDMI(Earc). BUT I will be trying this for the next few days , and its 100% not guaranteed to work. I am definitely a lab rat at this point. 

Also, Ive been told that Korea is working on this, as well is SONOS. they are STILL TRYING to figure this out. but Like the world we live in. Both sides are blaming each other. 

This took weeks for me to get ahold of this gentleman from SAMSUNG, and he is pretty competent. But like. he said. IF this doe not work, then it will be going to KOREA. I’ll keep you folks updated on what is happening on my end.
