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.

    [quote=rubberduck]This issue is all over the internet. It seems like people give up.

    I am using a view hd splitter from amazon that supports 4K @ 60hz with hdcp 2.2z This is needed for latest lg oled TVs c7 b7 and to support most hdr standards. If you invest in a Harmony Logitech remote you can control sonos tv splitter and Xbox from one source/activity. I would still prefer a hdmi option with aromos support. Ridiculous right now.

    Are you aware of a similar product that has the same specs, but provides more than 4 HDMI inputs? I have 6 devices I'd like to connect, and this box is almost perfect for my needs.

    Of course, if LG & SONOS could fix the audio delay issue, I wouldn't need an audio extractor and my options for this type of device would be greatly increased...

    Thanks!

    Are you synching the sound and video across multiple screens with that device?

    Can someone tell me if this extremely simple setup will bypass this audio delay fiasco? I'm looking to buy the LG OLED C7 or B7 television.

    LG OLED TV (C7 or B7)
    Playbar
    Apple TV

    That's it. If I turn off Dolby and go with Stereo, does that fix the problem? I don't do Surround Sound.

    I have the LG C7, Sonos Playbase, and Apple TV 4k. With the Apple TV 4K, I've managed to pretty much negate any lip sync issues. I have the audio hard-set to Dolby Digital 5.1 in the Apple TV settings, vs "Auto" which is the default. Prior to setting audio to Dolby Digital, I did have to mess around with the LG's audio delay settings, but was pretty easily able to get to a point where it was negligible.

    Can't say the same for my Xbox One X. Set it to DD 5.1 as well, but there's some pretty severe audio delay going on, which would be less of an issue if the Xbox had its own delay setting.

    I have changed the sound on my cable box,Roku,and blue ray player to PCM and all my lip sync issues disappeared I have an LG OLED C7P. Obviously either LG or SONOS fixing the issue is optimal and hope it will eventually get fixed

    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.

      As far as the LG C7 is concerned, I had the exact same sorts of audio delay issues with another sound bar, both via Optical and using the HDMI ARC input, while using other inputs (cable box, Xbox, etc). All native apps worked fine. Insofar as LG TVs are concerned, I think there's some laggy processing going on.

      See if your TV is outputting PCM Stereo or Dolby Digital 5.1, you can see this on the Sonos App.

      I've got a full 5.1 setup with Sonos Ones as the rears, so I'm not running PCM Stereo, though that does seem to eliminate any 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

      I'm have the same issues. But my setup does not include a playbar or a playbase. I'm using an LG OLED B7, set up by a regular 3.5mm mini jack audio cable to a paired set of gen2 Play:5's. As other users are describing, the sync occurs when the sound input is sorround, and not when it's in stereo.
      That means when watching Netflix, I can set the audio to stereo and have a descent experience, but other streaming services don't offer that option.
      My sound settings on the TV does not offer many options when it's set to using external speakers, and I am using the "bypass" sync option as well.
