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.

Same issue exists with the new LG OLED65C8PUA. I used an optical splitter, and this seems to fix the issue. As an added note, for those of you with a PS4/Pro that watch Blu-Ray movies, if you are only getting stereo, use the optical output (only reason I had the splitter) to have your PS4/Pro output 5.1

How did this fix the issue for you? I have an LG OLEDC7 and bypass it completely with an optical splitter but I still get delay with DD 5.1 on Xbox, PS4, and Directv, none with PCM. This has to be an issue with the playbase processing DD 5.1.

I just spoke to the LG VIP support representative She indicated that the firmware update to resolve the lip sync issue is scheduled to be released this Friday ( it may take a few weeks to be available to all consumers )- a hopeful development -

Has this worked for anyone? I am currently bypassing my LG TV completely with the sound but can give it a shot if the update has been released.

I honestly think the issues lies inside the PlayBar when Dolby 5.1 is being used, the PlayBar must be doing some type of processing causing an audio delay. Nothing we can do besides never use Dolby 5.1 OR use an HDMI audio extractor so the PlayBar gets the Audio before the TV even processes the image but then you'll have to constantly change the audio delay based on 5.1 or 2ch.

I have come to the same conclusion, I don't think it is the LG TVs, I still get delay on all of me devices when I bypass the TV completely and individually connect each device to the playbase with no splitters or interruptions. This is a sonos issue 100%. I even connected my old Vizio soundbar instead of the playbase and had zero delay with DD 5.1.

I have the same problem with a recently purchased LG OLED55B7V. Audio is delayed on dolby digital signals but fine with stereo PCM.

For me it's 100% the TV that is the problem.

I've tried audio direct from V6 box to Sonos Playbar, and sync is perfect.
I've also tried V6 to HDMI-splitter-with-optical-out, then from there HDMI to TV and optical to playbar and again sync is perfect.

But taking optical out from the TV delays dolby digital signals. Quite unbelievable that LG would ship such an expensive TV with such a serious defect.

Firmware version is 04.70.85 which is the latest right now.

Just an update after speaking to LG tech support. They acknowledged the existence of the issue and even conceded that it's due to the delay resulting from processing the dolby signal. However told me there was "nothing they could do" and didn't consider it a defect, but a "compatibility issue". And they have no plans to address it (that they were willing to share with me anyway).

Clearly it is a defect and quite a bad one for anyone needing an optical out.
Very disappointed in LG, just as well I only paid £1449 for the TV and not the £3000 it was this time last year.
For that reason only, I can put up with using an optical splitter, just bought a 3-in-1-out splitter from amazon along with a couple of optical cables - £24 total. It's USB powered with remote control, so assuming it works it's an acceptable workaround.

The optical splitter will work and it can be programmed into a Logitech Harmony remote to make the experience seamless.

The problem is still that any HDMI device you may have which doesn’t have a dedicated optical out will not be fixed.

I’ve switch to using the built in Netflix and Amazon Video apps, I use a PS4 and Virgin V6 direct to optical. It’s just my Nvidia Shield which I only use for Kodi which suffers. Luckily Kodi has an audio sync feature.

Thanks, I also have a media PC with Kodi, but as you say the Kodi setting can take care of that.
I'm glad to hear of someone else in the same boat as there aren't too many complaints against the exact model of TV as mine.

Or is everyone just suffering in silence, having bought their splitters and since moved on? :?

Hi,

I just purchased a LG OLED 55 B7V, a Sonos Playbase + Sub + 2x Play one because there was a pretty good offer in a local store. Now I just stumbled over this lip sync issue and it seems that there won't be a solution to this soon. Is it really that bad? I couldn't find any videos where the issue was noticeable. I would like to connect a BR player and a nvidia shield to the TV. What would you guys suggest? Returne the order, wait for a fix, purchase another TV or purchase another 5.1 System? I don't really get the thing about an optical audio splitter mentioned in this thred before. Would be great if somebody could explain it to me.

Thanks and BR

The easiest solution is to change your settings to PCM/STERIO on cable box and other devices. This will eliminate lip sync issues but you lose Dolby unfortunately Hope that helps

Hi Bigmanibids,

thanks for your fast reply but buying a pricey 5.1 system just to listen in stereo when watching all my blurays doesn't sound like a "solution" to me ;)
