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.

Any chance that LG remote is using something other than InfraRed to send signals to the TV? The Sonos can only ‘see’ IR, so you often have to tell your remote to use IR. See some additional data here.

Sorted! Thanks a lot!

Just came to put my own hat in the ring, 2018 LG TV with PS4 pro and Sonos surround system, exact same issue. I won’t be reading the entire 17 page thread but if they’re not going to properly fix the issue I’d even appreciate finer tuned audio delay settings...

Your rather lucky, if your talking about lip-sync issues here, I think LG TV’s can easily resolve such issues with this lip-sync feature available on their newer TV’s…

Some of their models also support HDMI/Optical port pass-through too in the TV Settings

…. and that’s without waiting for Sonos to fix anything at all here.👍

For what it’s worth - I was very nervous about purchasing a new LG OLED display since I own a Sonos Playbar system (based on the problems some of you are experiencing) - but I did go ahead with the purchase - and I have no audio delay issues with my LG C9 at all. It’s perfectly in sync (and I am a professional film editor - I cannot stand even the slightest sync delay).

This is my (admittedly) very simple and straight-forward setup - as I only use the LG C9 as a (stunningly brilliant) monitor for my Apple TV 4K. I do not use any of its internal smart features. No cable TV box or other external connections.

LG C9 55” (2019) - I was told it has the fasted internal processor (maybe that plays a role since the LG needs to pass on the audio to the Sonos universe), latest Apple TV 4K. PLAYBAR, SUB, BOOST, 2 Play:3’s (surround).

The Apple TV 4K is connected to the LG using its DOLBY VISION option, which also seems to automatically (and magically) configure some settings of the LG through the port it’s connected to. The Playbar is connected via optical audio cable to the C9.

When I set up my new system, I got all new cables (including a new high-end Optical audio cable).

I don’t know what did the trick here, but I was ready to use a (4K capable) external HDMI/optical audio switcher to fix any audio delay problems. Luckily I didn’t have to, as this is a much more elegant and simple solution (when it works).

I have a Sonos beam and two play 1s connected to 75" sony Bravia x950g via HDMI arc. I found that the tv video was ahead of the sound when playing through Sonos system if I was watching TV with a charter spectrum box. I had the sound delay sensibly set to zero on the Sonos app. However, when I streamed content through the tv via the Netflix or Amazon video apps, the sound synced up just fine.

I just now seemingly fixed the sound lag when watching cable TV by setting the 'A/V sync' to ON under the TV's audio output settings. When I had the A/V sync set to AUTO, it seemed to sync up sometimes. When I had it OFF, the sound lagged quite a bit. I hope this fixes the cable tv sound lag permanently and doesn't lag again for whatever reason.

Maybe this is a new setting on the Sony TV to fix this issue. I don't think I really changed any of the other sound settings when I first set up the tv months ago. It would be nice to get some guidance on the other Sony TV sound settings to optimize the Sonos experience. There are only a handful of settings that most folks are probably curious about regardless the brand of TV.

I am having a nightmare of time trying to get this issue straightened out. I recently purchased a new Sony Master Series XBR TV and I used it for the first time last night attempting to watch Frozen 2 with my daughter. The audio delay was atrocious. Mind you, I have multiple Playbars set up around my home and this has never been an issue so I was quite surprised when I had this happened to me last night. Any help any of you could provide to get this straightened out would be greatly appreciated.

While I agree with your irritation, this isn’t something that Sonos can be involved in. As has been repeatedly shown by people who “spend extra money”, as you’ve accurately put it, the Sonos works properly. The issue is in the ability for LG (and Samsung) to not delay the signal as it goes through the TV.

I replaced a TV recently, and looked at both LG and Samsung as potentials. I ended up with another Vizio, because I was confident it could pass through a Dolby Digital signal without delaying it. And I was correct, my Sonos continues to work perfectly, as it had on my previous Vizio.

I see that you a prolific poster here with this specific issue and I wanted to reach out to directly to see if you had any input in regards to my situation.

The Sonos HT device and its surrounds will only play the audio asap, when the TV has sent it to that receiver… so my suggestion would be to look at perhaps why the TV might be delaying the audio output through its port.

Perhaps switch off any TV audio enhancement features, check the interconnecting cable and ensure the TV firmware is running on the latest version. I’m assuming you are using a Sony TV in-built App for movie playback, rather than a connected peripheral, like a cable box or entertainment device, (Apple TV, Roku or Firestick etc.) If you cannot solve the matter it may pay to speak to Sony Support to see if they can suggest a way to deliver the audio output in a more timely manner.

Hope that assists.

I am not using the built in Apps as I have a lot of programming on my firestick.
