I have replaced an Arc with an Arc Ultra, attached via e-Arc to my Samsung QE55QN90B. They are associated with 2 Era 300s and a Gen 1 Sub.

When playing from my NAS, ( Ethernet connected Jellyfin source), I get a short drop in audio every minute / couple of minutes. Only lasts a second.   Sources from Atmos, to 5.1 to Stereo all experience it.

As it all worked fine with the Arc, I’m assuming it is related to the Arc Ultra 

Any thoughts on cause / resolution ?

 

 

 

Having the same issue here in Australia.

have the Samsung 77 90D with Apple TV and Ps5

not using the internal Samsung apps.

 

things I have tried.

using the Sonos HDMi cable provided (audio drop outs)

replaced all my HDMi cables with 8K high speed 

(audio drops out) 

 

trying with Atmos eARC setting to off.

so far no drops BUT….

the sound seems lower quality now.

interstellar has been my test film and audio.

going to do more research on eARC setting in the Samsung…

 

this is frustrating after spending so much money and time of this….

Since yesterday I unplugged all HDMI cables from my TV except the Arc Ultra via eArc. I do not experience those dropouts anymore. During my research for the cause of those dropouts I am watching content via the integrated Samsung TV apps. Can you try the same approach and check if those dropouts also disappear?

 

Hi I tried this and no dropouts once any other hdmi were disconnected 

Looks

Like a communication issue with the arc ultra and other inputs 

 

Netflix which is installed on my Samsung TV has no dropouts 

 

 

Glad to hear that. But tbh this can not be a long-term solution. I want to use my PS5 and my Nvidia Shield as well via the other HDMI ports.

Absolutely you are right I do use the hdmi for other inputs blu ray , firestick . I have added hdmi for the firestick back . I am going to try it again to see if the drop out problem comes back .

 

I may try a few other hdmi cables if the problem persists to see if changing the cable works .

If not I think we should raise this issue with Sonos and hope they provide a firmware update which resolves the issue 

Just checking in to confirm the CEC splitters solution: i was also having split-second dropouts every minute or so, with eARC and Pass-Through enabled. Managed to debug my problem and it only happened when I had other HDMI devices connected, everything was having audio dropouts - both HDMI devices and internal apps. Without any devices connected, the sound from internal apps was perfect. After searching for solutions, I tried a certified ultra high speed cable, however it didn't solve the problem. When I got to this thread about CEC problems, it clicked: as disabling CEC was not an option because my TV would not recognize the Sonos Arc Ultra, I ordered CEC strippers for my HDMI inputs and so far the problem is gone, no more dropouts.

Hi 

With you saying I presume when you added the cec strippers to your other hdmi inputs you are able to use the Samsung remote to control these other devices which are connected to your Samsung TV ?

I only ask as I have the same issue and have yet to try the cec strippers 

 

Thanks 

Just for info, and maybe it helps 🤷🏼
Samsung updates their firmware from time to time, the challenge is that if you search for updates on the TV it says there are none but there are. The update can be downloaded from Samsung's website and downloaded to a USB and then update your TV.

Have experienced this several times now.
I have a S90C myself and have not experienced any challenges.

thanks for the hint. actually I have the most current version. just checked it manually.

So I saw on Reddit they recommended swapping cables I bought this one on Amazon and I haven't had any cutouts since.

Same issue over here.  Samsung QN90C.  Latest AppleTV 4K.   Arc Ultra.   I am testing changing HDMI-eARC from auto to off.
