Arc TV sound cuts in and out.

Just got the Arc and have it paired with 2 Play:1’s and a gen 3 sub. 
Samsung Q80R tv. 
 

The sound from the tv will play for around 5 seconds and then cut out for around 1 second, play for 5, out for 1, on and on. 
 

I’ve swapped out the hdmi cable twice, tried unplugging the tv, switched between PCM and DD+ and switched between different apps on the tv. 

The sonos app shows that I am getting an atmos signal  


Was running a beam with the Play:1’s (but no sub) before just fine.

 

Not sure what I should try next.

 

Thank you,

mike

    Thank you all for all your efforts and testing. A system update has now been released which also include a fix to this issue (it disables the Sonos “screensaver” on an Arc if connected to a Samsung TV). Please update your Sonos systems. If you’re still experiencing problems after updating, please let us know.

    Just wanted to let everyone know that Sonos sent me a replacement Arc. After 5 hours , it also had an audio drop off issue when I was watching tv then switched to Netflix. I’m wondering if it’s the tv’s now and not the Arc’s.

      But we are seeing the problem with different TV’s. Samsung, LG and Sony are all having problems. I have a LG B9 and im having exactly the same problem as a user with a LG CX.

        @Krishma M I think an update from the engineering team is overdue regarding this issue. Could you reassure Sonos Arc buyers that a fix is indeed coming soon?

          So with the new firmware update eARC is really important when using an Apple tv. If not enabled the support for LPCM wont work. I really hope there is a fix in the new firmware or else it will suck using an arc and Apple tv.

            Its not fixed!!! Literally the first time i switch to my cable channels the sound drops completely. I had to switch eARC off and on for the audio to come back.
             

            This is not ok!

              What you’re seeing is that you didnt have a faulty Arc - they are all bad!  It’s not the TV’s fault, there is a clear design flaw with the Arc that we are all waiting for news on a fix.

                Happening now even when changing channels within the same (YoutubeTV) app. Not good. How long is the warranty? Really thinking of returning it. $800 is just too expensive for it to not work correctly.

                  Same issue Samsung 55 frame tv.  Sonos arc audio cuts in and out.  Has it professionally installed and the don’t know what to do .  Hopefully there is a software fix for this available very soon.

                  Reading on reddit and it seems as if a lot of people are having eARC issues. The new firmware update properly made more people switch to eARC and now they are experiencing audio drops.

                   

                  Sonos should really get moving on this!

                    Just came here to ask if this update fixes the drops, oh well, more waiting it seems.:disappointed:

                    From the consensus it seems the short audio dropouts or complete audio drop outs happen a lot with the Samsung and LG TVs. In fact I think it happens with any TV that has eARC activated.
