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.

    You need a HDMI splitter with audio out such as a viewhd box from amazon. If you have a harmony remote you can give everything to switch correctly automatcially, or LG could address the issue. Better still sonos should get with the modern age and use HDMI for audio, ridiculous

      Redesign the SONOS playbar/playbase to use HDMI passthrough so embedded audio stays synced.

        I have the same issue. Philips 55POS9002 OLED TV, Playbase and two Play 5's as surround. With the TV outputting DD 2.0 I have terrible lip sync issues. Switching TV to output Stereo improves the issue but it is not perfect.

        Looking forward to someone taking the issue seriously.

        This is either a sonos issue or tv manufacturer issue. I suggest , if you have not done so, contact support. We all want this issue resolved

        I have the same audio delay issue! The video on my tv is ahead of the audio on my Sonos Playbar, so frustrating and seemingly can't be fixed because I can't delay the video. The optical out on my tv is connected directly to the Sonos playbar. My tv is a Sony XBR65X850c

        I setup my Xbox One S yesterday with the optical out directly the the Playbar with the hopes of avoiding audio going through the TV altogether. It is definitely and improvement but I still had to turn the TV audio sync on with the bypass mode enabled. It is now close enough to not be distracting, but still not perfect. And if I want to chromecast something or watch something on an app that Xbox doesnt have, I am stuck swapping optical cables which is really annoying. Hoping that someday this gains traction. Sonos stopped responding to my ticket in December.

        I have an oled c7 with the playbase 5.1 setup and i have this terrible lag problem. I also have ks9000 that i had previously setup with the playbase 5.1 setup and guess what, same problem. All sonos keep saying its the tv. Really?!?!

          LG C7 user here. Bypass is better than any of the delay settings for me. Obnoxious. TG for the 45 day return window.

          I have a Verizon Fios 1100 (arris) STB box. The only way I can mostly eliminate lip sync is to change audio to stereo on the STB box. For my other devices Roku, blue ray player bypass appears to minimize issue I also will keep my LG C7. But wish LG, Verizon,Sonos could fix the issue

          Hello everyone. Quick update: The team is aware of an issue with LG OLED and Sony XBR TV's using Dolby Digital and lip sync. It'd take a firmware update to fix it on the TV's side of things, but we have no word on that. This can be further tested and verified by changing the audio from Dolby Digital to PCM (Stereo) or by testing the audio with another optical audio source such as your cable box. Thank you for your patience on this so far.
