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.

That's fascinating. Your evidence points to the fact that light travels slower through one cable than it does through another.

I continue to use the cables that came with both of my PLAYBARS (several years ago), and still have absolutely no lipsync issues on either of my Vizio TVs.

Yes can’t say it makes complete sense but it definitely seems to have made a significant difference. My lip sync was quite noticeably bad also but now seems normal, so either way I am very happy.

Just to also add, I didn’t previously have any lip sync delay issues with my previous Samsung TV when using the original optical cable that came with the playbar. Just FYI

I've got to think there's something else that was going on. Physics is physics, it doesn't change based on the model of TV, or the cable.

I also experienced lip-sync issues but managed to eliminate it.

My equipment and config:

LG OLED55C8 (HDMI ARC, DTV audio: Auto, AV sync adjustment: on, Bypass : on
Apple TV 4K (Change format:on, New format: Dolby Digital 5.1. Also enabled Match Frame Rate)
Sonos Beam (No change)
Sonos Ones x 2

This is the exact same Sonos setup I have and I am debating whether I should get a 65" C8 or wait for the C9 or new Sony A8G or A9G which shouldn't have these issues but will be more expensive.

By making the AV sync and bypass adjustments, do you lose any functionality on the Beam? Are you able to fully control it with the TV or cable box remote via HDMI ARC as intended?

I know myself and if I spend $2k on a TV plus what I have invested into the Sonos system, there is no way I am going to put up with it not working properly and having to do a work around to try to get it to work. I would rather wait a few months for the issues to be ironed out.

Any news on this. I have a c7 and a c8 with a playbase and beam and honestly would not recommend Sonos to anyone with any of these OLEDs. I am getting sick to death of the terrible lip sync and waiting for a fix for this. I have been waiting for nearly 2 years in the c7s case. Bought a c8 for the front room thinking it would be ok, but absolute no difference. Only fix is to use it on pcm and NOT in Dolby Digital which then you will NOT get 5.1 and only stereo which defeats the object. Most people see when changed to PCM and everything is in sync don't realise they are only getting stereo. Absolute Rubbish.
Be Warned.

I have that LG B8 and don’t get any lip sync lag through my beam (or playbar before it blow up) through the built in apps, uhd Blu-ray or Apple TV 4K but I do on my Xbox one x and PS4 weird.... but I can live with faux DD 5.1 on console and if my tv and movies are working perfect. I’m not updating anything just in case lol.

Im having the same audio delay with Samsung QLED as well. For example, If I use Bitstream and Dolby, there is audio delay. If I use Bitstream and PCM or stereo there is no audio delay. I have a surround sound 5.1 setup with Sonos speakers, so PCM does not work with surround sound.

When I call Samsung Support, they say it’s a Sonos problem, then when I call Sonos, they say it’s Samsung! How about these companies work together on behalf of the customers instead of having customers go through hoops to make make their tech work properly?
