I have an LG 86Nano916 screen, and a Sonos setup with an Arc, 2xOne SL and a Sub. New, high quality/capacity HDMI cables etc. It all worked perfectly when I set it up, including Dolby Atmos from Netflix streams via HDMI/ARC. It was stable for about 6 months.

A couple of months ago it started to show intermittent problems, with the sound disappearing randomly. Sometimes a screen power-cycle would resolve whatever the issue is/was. Now - to my irritation - it doesn't work at all. There have been NO changes in components or connections since setup. The only changes are the software updates that my LG screen and Sonos insist upon every now and then. Everything is on the latest version(s) of firmware etc.

Is it possible that these manufacturer updates are the source of the problems I am experiencing? That there are compatibility problems now that didn't exist when the system was set up?

In all honesty I don't have the appetite to get involved in what will inevitably a game of each party (LG & Sonos) looking to blame each other. I would just like my AV stuff to work as it did when I invested time and effort in setting it all up.

Posting here to see if anyone else has similar experiences with LG/Sonos kit, or would like to offer any advice on what may have happened and how to resolve it.

Welcome to the world of Digital

The world where all our problems go away, they said.

The world where stuff just works, they'll talk to each other, they said.

When its a world where so much is hidden we don't know what talks to what or even how.



There are a multitude of things that could be wrong or failing.

Obvious ones are the digital cliff on your connections.
Just because it works does not mean it is working well or ever has. Signal quality could be perfect with no digital errors at all, or could be 1 more error away from failure. Just because you had a good picture doesnt mean you had a good signal. As time goes on, cables and connections do degrade potentially pushing of the cliff and into a point of failure.

Or it could be the coders and the firmware upgrades, just pushing the communications further and further apart each upgrade. No one knows they are doing it, because they can and dont test connection combo or hardware combo.

Do you use the sonos side of music or via its own app at all?

How does that bit work?

Sonos audio via the Sonos App works fine.

The issue with the TV sound manifests as the TV audio-out switching itself to “Internal Speaker” after random periods of time. Sometimes switching back to ARC works, sometimes it doesn’t.

It’s infuriating. Especially because it was working and stable for six months with no problems.

So it seems closer to an internal LG issue than a link issue.

Does it autosense the ARC connection or manual.

Can you get into the settings to manually set it?

Mines and older set up with an LG 55EG960V and a Playbar and yes i have had this exact problem over the 4+years i have had and agree it can become infuriating. It actually occurs sometimes when changing channels and the sound disappears. the only solution i have found is to disconnect the Playbar in settings and connect again as a new device. Its probably happened a dozen or so times during ownership so i have accepted it as I always assumed it was due to incompatibility as when i first purchased Sonos was not an option and i had to set up as a Phillips to get working.

Yes - I think the issue is at the LG end of the chain. I did have the “Digital Sound Out” set to “Pass-through”, but have now changed it to Auto as per this: https://en.community.sonos.com/home-theater-228993... but that hasn’t solved the problem.

Evidently I’m not the only person experiencing issues with LG & Sonos. V frustrating - especially as it worked perfectly for months…

Thank you for your help btw.
