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.

I recently went through the trouble of updating the software on my 2020 Samsung Q80T to 1460 (not sure why but only available as a download to a USB stick). Seems to have made the problem worse. Changing channels on YoutubeTV drops sound. I doesn't come back unless I either change the audio source on the TV and then change it back to the Arc, or change channels and change back (this sometimes works but not always). So Samsung does not seem to have fixed the problem yet, and haven’t seen a Sonos software update is quite a while, leading me to think that Sonos has taken the position that its not their problem.

I worry about these updates that show up for download but not pushed over air. Feeling like we’re getting test versions. If it is worse than previous, can it be rolled back to previous version?

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?

Well it seems LGs recent 3.21.09 and 3.21.16 firmwares for CX/GX have improved the issue, I would go as far as say its fixed the issues, but I only installed the firmware the other day so can’t say for sure.

Although the firmware notes do not state audio/eARC fixes I believe the firmware does contain fixes for audio issues, Ive seen a lot of owners say these firmwares have fixed their audio issues.

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

I’m sure I read somewhere on AV Forums that the issues on this thread seem to be mostly happening on all of the 2020 models like the LG CX, Frame etc rather than the 2019 C9, something to do with how eArc was set up on the earlier model.

I am going to get on to Sonos support today and hopefully they can help as I am getting nowhere with Panasonic, they are saying it is down to the the way Netfilx, Prime etc configure their apps its not Panasonic. Everybody passes the book to somebody else, its depressing!

This may help/may not. If you have Sky Q, change picture settings to 8 bit. I get sound interruption if set at 10 bit. Wierd...

1460 appears to have pushed over air for Frame. Folks seeing any improvement? I still have to restart Sonos with 1460. Seems it still can’t handle a audio stream start, like tv coming out of sleep or art. But can reboot into an existing audio stream.

Having 1460 on Samsung Frame with sub and play 1. super disappointed that this is working faulty and even more to see it is known for almost a year now. Sorry Sonos...we spent good money for your system, go figure and solve it. Be customer-focused please

I have a Samsung Q70 and have random issues when changing between Netflix, Youtube, TV etc. the sound just drops out. Usually have to unplug everything to get it working again.

I am having the same issue. Have an LG OLED55C6B. Had arc less than a week and sound just stops completely and reverts back to TV speaker.

not what I expect from a sound bar that is nearly £1k.
