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 audio sync issue on my Philips 55POS9002 OLED TV. The issue is intermittent. Sometimes lips are in sync. Usually when my devices are rebooted. My setup is: Sonos Playbase with 2x Play 1 as surround and Apple TV 4K connected to my TV with HDMI.

I have the same slight delay with dolby 5.1 through HDMI bitstream (switching to Linear PCM 'stereo' is fine, but obviously clearly lower quality) using ps3 and a Sony TV. very annoying, seems to be no setting on the TV to deal with it, and the SONOS controller audio delay only works with audio that's ahead of the picture, not behind. i noticed it on a Dolby TrueHD blu ray (The Godfather trilogy), don't know if that has any effect as opposed to standard Dolby 5.1?

As a side note to my previous post. The picture in my case is also ahead of the sound.

turning off 'Reality Creation' in the sony TV picture options seemed to help.

Any chance you tried Game Mode on the input the PS3 is connected to?

No - can't find a Game Mode option on the TV actually. But as far as I can tell turning off 'Reality Creation' seemed to help.

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

If anyone here is solving lip sync issues by setting to stereo you have just wasted 700 bucks. The whole point of sonos is to at least achieve surround sound through 3.1 or 5.1 switching to stereo is degrading the system. Buy a hdmi switch with audio splitting. It is ridiculous there is lip sync issues in first place. I paid 3k for an lg oled tv and still have to pay for a splitter to solve the problem. Sort out the firmware and provide and hdmi option in future

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.

Or you could have provided an hdmi option instead of an old unused optical option

This issue is all over the internet. It seems like people give up.

I’m using a playbase, LG C7 oled, and Xbox one S. There’s a delay when the Xbox is set to bitstream surround, but not uncompressed stereo.

The way I mitigated the audio delay was by running my optical directly to the playbase, from the Xbox one s. Not ideal because you give up the TVs switch capability. but it works.

The problems everyone seems to be having originates at the hdmi to tv/ tv optical out to playbar playbase pass through.

The sonos app has an audio delay, but it doesn't seem to have any effect. Super frustrating.

I am using Xbox one x with bitstream out via hdmi to a hdmi switch and optical cable from switch to play base. This is only way I could solve lip sync issues.

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.

I have thought about this option... waiting and hoping LG fixes this.

I regret not researching this particular combo before, as anyone here knows the Sonos and Oled TVs are an expensive solution to not tearing your house up, or running cables everywhere.

What is really sad is that what is being acheieved is a rather basic form of surround... with really expensive equipment.

I would think there is a higher level individual at Sonos that may have a relationship with someone at LG.

We are all after all customers of both companies. Would it be too much to ask for this?

I am not blaming Sonos, but, you folks probably have industry contacts that could be made aware... at the very least on our behalfs.
