I've been living with lip sync issues (audio behind the video) since I got my Playbar about a year ago but I finally decided to do something about it. After multiple conversations with Sonos support and the LG's support people (they kept blaming each other for the audio delay), I decided to email Sonos' CEO about the issue.
After a few hours, I got a reply back from him, CCing a team manager who was going to look into the issue. We scheduled a call and he had me send various diagnostics to him. He said that the engineering team was going to investigate and get back to me.
A week later, I got an update. He told that they are still working on the issue. He also said that only one other person had reported the same issue (I assume that means that only one other person with an LG TV). So, if you're having audio delay issues and you've tried all other troubleshooting, reach out to Sonos support and have them look into it. If it helps you might mention my reference number, which has already been escalated:
Keep in mind that my setup is pretty straight forward (LG C6 OLED TV connected directly to the Playbar via Optical, audio playing from the built-in apps) and every single thing LG and Sonos suggested, including going into the TV's service menu and changing things there.
I know there are multiple post on the topic so hopefully we can solve at least some of the issues causing audio delay.

And also, keep us post !
No amount of fiddling could get the sound from the Blu-ray player in sync with the picture though, as others have observed the picture was arriving first, so audio delay settings couldn't help. Sound from the internal Apps was perfectly in sync.
I found many threads complaining about this and after seeing how old some of them were decided that I didn't want to wait for some mythical firmware fix from LG, and after spending so much on a TV I'm not prepared to have to buy an external switch and add to the AV cable clutter just to workaround something that so obviously should just work.
It's clearly a TV problem, so it's going back, and I'm going back to reading TV reviews again. LG have lost me as a current and future customer.
That is indeed what is usually recommended (you theoretically get a better audio signal since it goes directly to the speaker and is not passed through multiple sources).
In my living room I have:
65” Samsung KS8000
Sonos beam connected directly to tv via HDMI/ARC
2 Sonos One’s set up for surround
1 Sonos Sub
I don’t seem to notice any issues. I only watch cable tv and stream movies via VUDU and shows on Netflix. Seems to work great.
In my upstairs loft however is where I do much more and have the following setup:
65” LG OLED B7A
Sonos beam connected directly to tv via HDMI/ARC
2 Sonos One’s set up for surround
Xbox One X hooked up to tv via HDMI
PS4 Pro hooked up to tv via HDMI
I feel like I did not notice this until reading online and seen a bunch of issues. Now I cannot stop looking at people mouths when they speak. It may be in my head because the wife say she doesn’t notice (she’s not a techy like me though) watching cable tv and playing read dead redemption 2 I seem to notice this slight delay. The TVs internal apps again like VUDU for movies and Netflix it seems spot on.
One other thing that seems weird to me is dialogue in gaming (only tried on RDR2 so far) that when voices are coming from the LH and RH surrounds they are louder then when coming from the front facing beam. I would think it should be the opposite.
But anyways this is still an issue with the beam connected via HDMI right? Not just the older playbar and base via optical?
Just to clarify, my ATV is set to output DD5.1. And my beam was connected using ARC. There is a lip sync issue with all apps except the TV+, which for some reason is perfectly in sync. Just thought it was strange. When I connect to the beam using optical everything is in sync anyway.
I was just experimenting as I would like to go back to ARC instead of optical as it’s just messy using audio extractors and optical switches, and would save a lot of excess cables behind the tv unit.

Any ideas?
Hmmm, this has me rethinking my Sonos Arc preorder. My second choice is the Sennheiser Ambeo, but those can develop a glaring problem over time (center channel becomes muffled for some reason). It’s also around three times more expensive than the Sonos Arc.
Only reason I’m trying to replace my 3.1 system is I want Dolby Atmos when watching all this new Dolby Atmos content and I cannot add separate Atmos and rear speakers.
So you've connected your sky box straight to the beam and now have no lip sync problems?
This is where I'm stuck at right now, actually. For example, if I plug my NVIDIA Shield into an HDMI Switch, apps like Netflix/Prime come out only as stereo. The TV is what's been converting the DD+ signal to DD, so without the TV's involvement, the Sonos won't play the DD+ signal. So the Nvidia shield has to stay plugged in to the TV, which means the Sonos has to stay on HDMI-2 (ARC) to get the sound converted by the TV and not the splitter.
However, the issue now is my 4k player. The player is what needed the splitter, and now that the Sonos signal isn't running out from the splitter (via optical), I'm back at Square 1.
Which leads me to my next idea: Could I get a splitter for the Sonos signal? If I were able to have two inputs running to the Sonos, I'd be able to run my 4k player's picture to the TV, and the 4k player's audio to the Sonos (my 4k player has two HDMI ports..one for audio and the other for video).
So I just spoke to the UK support. I was told that because sounds comes out then there is no issue. As I had checked the settings there was nothing else to do and everything was working as expected.
On that note does anyone know if any other OLED TVs exist that don’t have this issue. Are Sony TVs still having it or are they fixed now? I’m going to sell mine when I can find a working replacement and I’ll not be touching LG again.
Adding my name to the list, 49SK8500PLA (LG 2018 nanocell) and Sonos Beam. HDMI devices such as FireTV stick and BT TV box show significant (300ms or so) audio delay when set to dolby digital, fine with stereo. Tried all the settings under the sun to try and get the TV to passthrough the audio as is, adding no delay. Tried talking to LG support but they said they couldn’t reproduce the issue.
Here’s hoping we get some kind of help for this, as it looks like a serious problem.
Keep us posted! What was the date of the update?
Keep us posted! What was the date of the update?
The auto update only happened today, but it updated to firmware version 5.80.15 which was a significant jump from the previous version. Hopefully it had a lot of bug fixes.
Unfortunately the PS4 Pro still has terrible lip sync, however as this is the only device still experiencing issues for me and I never watch physical disc media anymore, I really don't mind putting the PS4 Pro in stereo mode for the odd game I play.
This has meant I can now thankfully remove the annoying optical switch I had setup. I hate extra clutter behind the TV and adding in extra cheap devices in between expensive equipment.
You may have already looked at this solution. I bought it last year on the recommendation of this forum, as my TV is old school and doesn't pass through 5.1 at all.
It works very well, and they seem to indicate that it supports pretty up to date video standards.

I can't vouch for that, I've yet to upgrade beyond my 1080p plasma. But the product is awesome and they have solid support, so it would be worth at least an ask.

Funny coincidence : I sent few weeks ago a registered letter with acknowlodgement of receipt to Mediation Department of LG mentionning the URL of this discussion.
Which TV are you referring to, and what firmware version?
This seems to be the solution for me as well. I have the J-Tech 4K 60hz HDMI audio extractor (HDMI from cable box to J-Tech, HDMI out to Samsung q60 HDMI input 1, optical from J-Tech to Playbar). Solved the problem with audio sync but I can’t get Apple TV audio without switching the hdmi inputs to the j-tech.
Thanks
