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.

Same problem here with a Panasonic HZ1000 OLED. Iv had a Playbar since it was first released and it’s been faultless. Bought a new tv so thought I’d take advantage of the eArc functionality and the Dolby atmos so bought an arc. Absolutewaste of money it’s going back! The only way to get Dolby sound on the internal Prime app is to switch the Arc off and then back on again and it will then work intermittently for a while Then it disappears. The only way then to get sound is to change the format to PCM which is output in stereo 2:0 only. If I then switch it off and back on the same thing happens again. Replaced all cables etc as well.it’s no worth the money so is going back unless it gets resolved by support,

If you read some of the previous posts.. you’ll see it’s not a Sonos issue… tv manufacturers are coming out with firmware updates that are fixing this issue..

I’m no av expert so don’t know if it’s Sonos or the set manufacturer who’s unable to sustain the Dolby signal but it seems odd that it isn’t localised to one tv brand and is almost universal in its application suggesting to me it’s the arc not the tv, but I may be wrong who knows. All I know is that the playbar output 5:1 fine but now the arc can’t do it or should I say it can but the signal quality is terrible and gets worse the longer I watch something on the internal tv apps.

Iv looked online and also tried a software update on my TV and nothing is currently available my tv is up to date. Panasonic don’t do many updates and the new 2021 models will be here before you know it so I’m left wondering whether I should keep the arc or return it and go back to my playbar.

Maybe get a different tv brand that has the newest updates?? Panasonic is not a popular brand...

I think you just like to wind people up.

I really don’t think that would make a difference anyway as it seems from reading this thread the latest updates on other brands of TV are not working either. Its seems its either return the TV and wait and hope the 2021 models from all manufacturers are better equipped at passing through the signal needed for the sonos to work (if it is a tv problem) or return the sonos and purchase a soundbar that doesn’t have this problem as other soundbars don’t seem to suffer from this judging from what i have been reading on AV Forums.

This seems to be the most active thread so I’ll tag on to try and pressure Sonos for a solution.

Samsung Frame 65” 2020 model and Sonos arc

Sound cuts in and out every morning after being off. This happens on any sources that come trough the TV. Music plays fine.

Unplug and repluging either works as long as the TV is not turned off. Different HDMI cables don’t help. Optical converter solves the issue but doesn’t provide ATMOS for sources which have it.

I loved Sonos, and have them throughout my house so the optical converter is my “solution” until we can get to the bottom of this.

Please Sonos, help us!

Thanks for the update, much appreciated! Crazy you had to update us and not Sonos jumping in on this thread.

Guys,is there a TV that actually works with Sonos Arc for ATMOS? So far it seems like LG, Samsung, Sony, Panasonic, TCL, Hisense, Vizio all have issue with the Sonos Arc with audio cut out issues and no fix available yet. Is there even a TV that work for people here?

My LG C9 TV is working fine here and I get Atmos output.

Yep..my Sony works great. Sony came out with their firmware update a couple of months ago...no issues.
