Arc TV sound cuts in and out.

I have this problem as well. 2017 Samsung Q7F. The soundbar cuts in and out so frequently, I am ready to get rid of it all together. It’s mind blowing that this issue is ongoing for over 2 years without a solution. 
 

All I have been doing is “resetting” the system by unplugging from power for 10 seconds and replugging in, or changing the output to TV speakers for 10 seconds while messing with volume then changing back. Still not a solution by any means….

Have you tried switching off HDMI-CEC on your ‘other’ HDMI connected TV devices, or if unable, inserted a CEC-LESS adapter to stop them stealing the focus away from the soundbar? Doing that normally fixes the issue for many with that kind of audio-dropout issue.

Hello, has this issue been solved since then? I have a Samsung Frame 2021, and considering to buy a Sonos Arc, so I’d like to make sure I won’t have any issue. Thanks for your answer. 

Hi @ stueyB did you manage to find a solution as I am having the same with my LG OLED TV and arc .... It is so frustrating as the amount of money I spent on it

Unplugging the arc and plugging it back in solved it for me for about a week and I’m back to it cutting in and out,  any fixes from Sonos?  I don’t want to have to plug and unplug it all the time 

Hey I returned my Arc under John Lewis warranty and my new one is working as expected now... 

Have a home theater with a Samsung QN65Q80BDF TV, Sonos Arc SL, Sonos 1 SL x2, Sonos Mini Sub,  and a Sonos Move. System worked fine for months then suddenly sound would cut out upon turning the TV on for seconds then come back on and off for 2-3 minutes then the sound would be fine. When I turn TV on again, the dysfunction repeats itself.   I bought a 8-10K eARC HDMI cable ($$) which initially fixed the issue for a brief time. Now the problem has returned.  I have contacted tech support for both Sonos and Samsung without resolution each blaming the other product.  I have resigned to living with the issue, but don’t think I should.  My Tv and Sonos is still under warranty.  Any suggestions?

I have heard thousands of complaints on this same problem. With no fix. The smart thing to do is demand a refund. Return the speakers. Tell everyone that you know why you returned and stop buying Sonos until they care enough to fix the problem. When they see sales drop and subscribers leave then they we learn. What good is sound quality if you can not enjoy it without interruption. I am going to another system. I have no time to waste on this anymore.

Visited here to see if this was an issue, also have Arc Amp, Sub & Samsung 8k and it’s annoying that it keeps cutting out the sound. On the lasted software etc. 

So I also have the problem on my lg c2. Sound is off when I switch hdmi source or even happens when I switch from Netflix Dolby atmos to YouTube video, all internal apps. Switching sound source to tv speaker and back to HDMI solves the issue temporarily.Freaking annoying. Never had this issue with my Samsung soundbar. I think it’s Sonos.. regretting so much my god..
