I have a sonos ARC and sound keeps cutting out for 1-2 seconds and then picks back up. My sonos was fine for about 1 week after purchasing but now the sound will cut out periodically. Here is my diagnostics number 103248445. How can I fix this issue?

Same here. Very aggravating. Diagnostic report 490235596.

This used to be an issue with some TV’s, particularly with Samsung and connected sound systems using HDMI-ARC/eARC, where other connected peripherals like Apple TV (as an example) tried to steal the CEC focus.

So maybe try disabling CEC on any other connected devices and then power off all for a few minutes to setup the handshake again and see if that perhaps solves the matter.

same Issue Here. I Have Sony A80J , I cant watch any Movie with Atmos sound.

What source App are you using? If it’s Netflix, then ensure you have their (higher level) premium subscription and that Dolby Atmos is shown near to the title of the TV/Show - Also what is the current audio output that’s showing on the now playing screen in the Sonos App when you’re playing any Atmos source?

Yes. I have the Netflix premium Suscripcion.
I see “Atmos” in the Sonos App when I play movies with Atmos sound. Is not the issue, I have Cutting off when its play movies.

Thanks for answer! And I hope Sonos fix this issue.

Have you tried switching the HDMI port from eARC to Arc to see if that solves your issue?

I had this problem about a month ago, and I went through the suggestions mentioned here, and then purchased 8K HDMI cables to ensure I have everything needed to run smoothly, and the sound cut out again last night watching HMO Max through ATV. The movie was 5.1, although I thought it was a known issue with Atmos.

Hopefully there is a fix coming soon, because the suggestion of unplugging all electronics is not a solution.

We had a similar issue with our LG C1 and the Arc. I changed the sound output to the TV speakers and then back to eARC. That seems to have cleared up the issue here.
