If you're experiencing audio delay issues, read this

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.

I have the same problem with the same television. Very frustrating ?

I have the same issue using the PLAYBASE + SUB, both on wired Ethernet, using the LG OLED65E7P TV. No amount of adjusting A/V sync settings on the TV or the SONOS app have resolved the issue. I can get close to great A/V sync as long as each output device is set to stereo only. That sucks, but at least it’s watchable.

I’ll keep monitoring this thread for a fix, and I’ll contact LG and SONOS again. It’s really disappointing to experience this with such otherwise great (and expensive) equipment.

FWIW, I bought a splitter and am now going directly from Sonos to each device. This did resolve the sync issue & everything is working great. I don't think relying on a 3rd party is acceptable, but is what it is I suppose....

Which model of splitter did you use? Does it extract audio from HDMI or just split optical signals? Thanks!

Hey guys,

Same here Im afraid. Just purchased a week ago :
LG B7
SONOS Playbase

...Delighted by the display but really disappointed by the Lip Sync.
I especially purchased a Playbase as my 2 Play 5 Gen 2 suffered (as expected) of bad audio delay.

I tried all fixes that I read online and here on particular but I can't seem to fix it.
This ruins my overall excitement to have acquired such great piece of hardwares.

I was on the market to invest in 2 more play 1 + Sub to complete my 5.1 equipment but I won't go ahead until this is fixed. To be fair I feel a bit of a fool now that I ditch over 2,500 Euros !

I will contact both Sonos and LG Support Team but reading your previous feedback I am not overly optimistic.

Hi to all, same problem here even with the newest LG firmware.
OLED55C7V with 04.70.65 just updated two days ago.

The german LG support says they don't know anything about audio delays ... funny, mailed them a lot of forum-links.

I use a Ligawo 3080026 HDMI HDR Switch to solve the problem, but i would love to not have to use this additional peace of hardware.

FWIW, I'm having the same issue. Have only really noticed it while playing a game on my Xbox One. When I play with headphones, everything is in perfect sync. When I play over the Sonos system, everything has a delay. After some searching, I was hoping to find a solution here, but no such luck. 😞

so excited to finally set up my system, but so disappointed in the sync as listed above, I wish I would have known about this. I'll call LG, but this seems crazy that this isn't fixed yet. What else do we need to do???

Sync Issue with:
LG OLED65B7A
SONOS PlayBar and SUB
Connections: Apple TV 4K > HDMI > LG > Optical > Playbar

I just called LG about this, and their VIP support told me that the engineering team is still aware of the issue and is investigating. They could not provide me with an ETA on the fix, unfortunately.

Also, in playing with settings, I found that turning on A/V Sync Delay, then setting it to 'Bypass' significantly improved the sync. It's now barely noticeable, which is an enormous improvement on what I was observing before.

I have found a partial solution to the audio sync issue for my lg c7 and playbar. I have set all device audio ( roku,Verizon set up box ) to Sterio. I also set audio sync on and tv with bypass on. It seems to solve lip sync problem but not optimum I hope LG really solves problem

I also chatted with LG and received the same standard answer that I read in the forum - known problem- engineers looking at it - no ETA- also frustrated and wonder whether LG is actively trying to solve issue
