Arc TV sound cuts in and out.

758 replies

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.

Hi, I've recently had this issue on a brand new setup of Samsung QE55Q90 and sonos arc connected through eArc in the TV. Every so often the sound would start to drop for about a second every few seconds. Only way to fix was to unplug sonos arc from the mains and restart it.

I see other people have mentioned problems after using the Nintendo Switch and it dawned on me that I've only recently plugged the switch into the TV and the sound drop outs appear to have started since then - it definitely didn't happen for the few weeks I've had the sonos before then.

Have unplugged the Switch completely and will report back if the sound drops out again

I know it's difficult to test for all permutations of AV equipment but I don't think this is really good enough for such an expensive soundbar.

If the matter is resolved, then try switching off HDMI-CEC control on the Nintendo Switch.
I think (but not sure?) you have to goto "Settings | External Inputs | Bravia Sync Settings | Bravia Sync Device List” to switch it off - at least that’s what was mentioned online.

I manually updated (download firmware, put on usb, update from usb) my Sony A9G to the latest firmware - release notes mentioned soundbar integration enhancements. Normally this update is rolled out automatically by Sony but it could take weeks or even longer till you get it.

No sound cuts occurred since this update. My sincere advice to Sonos is to really adjust and be more clear in your communication.

Apparently the integration with soundbars by TV manufacturers requires improvements and impacts Sonos as well. From what I have read, these issues also happen with equipment from Bose and Denon.

And yes, these issues should have come to light in the QA process of Sonos when doing integration testing. They were easy to replicate, but that is a learning I guess for future products.

You mention Bravia in your post when he has a Samsung. I’ve only known Bravia to be related to Sony.

I imagine there are similar settings on my Samsung so is still useful information.

So far,I have not had the dropouts since the Nintendo hdmi was unplugged so may be related to the Cec channel.

I also have issues with my Virgin Media V6 box and Cec with regard to turning on and off from the tv, eg turning on the tv sometimes turns off the virgin box and it all gets out of sync.

None of this is really good enough for a brand new £2K setup but I was aware of the eArc,hdmi 2.1 teething problems but hoped the manufacturers will carry on testing and bug fixing.

Merry Xmas!

Ah sorry, my mistake, I saw the Sony A9G mentioned in famschopman’s post and made the error of thinking that related to your post. For Samsung devices, I understand they call HDMI-CEC standard "Anynet+” - and as another user here, I was just trying to assist.

Your VM V6 box has no option to switch off CEC, but there are CEC-Less adapters to cater for that situation.

Merry Christmas to you also.👍

I experience various issues:

sonos system only plays music on arc, while the other speakers remain silent. Seems to resolve after resetting the wifi in some cases.
samsung frame 2020 tv and sonos arc seem to fight all the time. Sometimes the sound stops, turns on, stops,…

very disappointing after this longer period of issues being reported…?!

This is just ridiculous, I spent $3000 for the entire setup and this is the 10th time I write on this forum with another issue since June.

I have exactly the same issue, used to be weekly but now its MULTIPLE times throughout the day!

I have a Q95T Samsung, a PS5, and Sonos Arc with Sub + LB + RB.

I restart the Sonos Arc and then its not even discoverable through the Sonos app, I have to do multiple restarts, when I do, I can access the app but then everything else is missing from the App other than the ARC so I have to restart the surrounds and the sub.

It keeps happening when I switch between PS5/TV or TV ambient mode and Spotify.

Samsung got an update a month ago I don't know if that’s the issue or Sonos are just completely trash but Im just so frustrated at this point.

If you goto “Settings/System/[Arc Room Name]/Surround Audio” and switch Music Playback from ‘Ambient’ to ‘Full’ ...see if that solves your issue for playing music.

If the Arc goes missing from the Sonos App, my initial thoughts are that its more likely a local networking issue - probably WiFi interference perhaps. You may find this video can be helpful:
