Arc Ultra and Samsung Tv - audio drops

  • November 3, 2024

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 ?

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

    Hey,

     

    I was the one who had previously suggested switching the ER setting to off from auto. For me this fix the dropouts, and Atmos content still played fine, but Dolby 5.1 content just gets down mixed to stereo.

     

    I have also tried new HDMI 2.1 cables, and I still get the dropouts

     

    i for the CEC strippers but then I couldn’t adjust volume and power from the Apple TV remote. And I’ll double check but I feel like I still got drop outs. 
     

    can anyone else confirm if the HDMI CEC strippers have and still work?  

     

    rhis sucks!

    For clarity, when you switch eARC from auto to off - there are no more drop outs but virtually everything except Atmos gets down mixed to Stereo PCM?    I have had this exact same experience.

     

    Something else that is interesting is I tried the Arc Ultra on my older Samsung (2020) and i don’t get any drop outs from the built in apps or AppleTV 4K but I do get them with a PS5.    If I replace the Arc Ultra with an Arc - zero issues.

     

    to me, this clearly means the Arc Ultra is causing the issue

    hello,

     Yes that is correct. And I fo think it is the Ultra as well. . 
     

    I just checked and put those CEC strippers on the 2 inputs I want to use (Apple TV and Onn pro streamer). This stopped the DROPOUTS!! 
     

    But then Apple TV remote wouldn’t do sound or power for the tv. But I took the stripper off the Apple TV input and the remote works for sounded and power! I left the CEC strippers on the cable input for the Onn. 
     

    so I think I may have found a solution!! I got the CEC strippers off Amazon.

    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….

    I have your exact set up and the thing that resolved the drop outs was to unplug the Samsung Q90D from power and leave it for 30 seconds. When I plugged back in I’ve had no issues since. Been enjoying my Arc Ultra for over a week without issue.

      I posted before that the cable fixed mine, I was wrong it didn't. Sorry for misleading anyone. However turning off earc did work but obviously that's not ideal..

      I just tried a CEC stripper.  No change.   Drop outs still persist

      Grrr. I saw that post about disconne ting power cord and tried it. Now I am in a worse spot than ever. Now even if I only have one thing plugged into, I am getting dropouts. This never happened before. 
       

      going to try using CEC strippers and just posing ability to control volume and power with Apple TV remote. 
       

      but what is going on here? It was working fine with two things plugged into and the stripper on the second device. No drop outs and I could still use Apple TV remote to turn on tv and adjust volume. No more. 
       

      I am sad. I will have to turn eARC Zoff and have all 5.1 stuff go to stereo if these strippers don’t work. 
       

      sonos really needs to get their dhot together. I haven’t reached out to them yet cause I figured they’d just blame robl on the TV, but has anyone else reached out lately?
