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.

Hi,

I just purchased a LG OLED 55 B7V, a Sonos Playbase + Sub + 2x Play one because there was a pretty good offer in a local store. Now I just stumbled over this lip sync issue and it seems that there won't be a solution to this soon. Is it really that bad? I couldn't find any videos where the issue was noticeable. I would like to connect a BR player and a nvidia shield to the TV. What would you guys suggest? Returne the order, wait for a fix, purchase another TV or purchase another 5.1 System? I don't really get the thing about an optical audio splitter mentioned in this thred before. Would be great if somebody could explain it to me.

Thanks and BR


The other option mentioned is to have an optical cable from each media source connected to a splitter which then outputs to the Playbar. (e.g. I output my audio from my Sky Q box to the Playbar rather than from my TV) This will bypass the TV for audio signals to the PlayBar.

Edit

The limitation with this option however is that built in apps on the TV won't work.

Not so, I've now got my splitter in place and Netflix App on the TV plays perfectly going from optical out of the TV -> Splitter -> Playbar.
It was fine direct from TV to playbar via optical and adding the splitter adds no further delay.

So I think this is a good workaround.

Okay, I wasn't considering a TV optical link when I wrote my reply to avoid the lip sync issues but if the TV output is also connected to the splitter then the Apps will work but perhaps with lip sync delays.

Nope, it's perfect, thankfully! 😳

Is the hdmi arc on the beam going to help with these issues? Considering buying a b7 with beam 5.1 (2x ones and a sub) but am pretty hesitant after reading this thread.

I doubt it will change anything. It’s pretty much been confirmed that it is a TV issue. For some reason the TV’s can’t process the 5.1 pass through from a HDMI source. Remember it’s only an issue on devices that can’t use a dedicated optical. You could try it out... Sonos has a 100 day return policy if it’s a problem for you.

Hi,
I’m experiencing similar audio delay issues with an LG OLED55B7V and a Playbar with external sources. I’ve contacted LG who are sending an engineer to replace the main board. I’m sceptical as to whether it will do any good, but let’s see. Otherwise may look at returning the TV, as I’m convinced it’s not the Playbar.

What is the source of the input to the TV? If it a Sky or Cable box that has an Optical output, can you please test with the optical connection to the Source rather than the TV?

The sources are either a Humax Freesat box, or a Blu Ray player, both set to multi-channel audio. I haven’t tried straight optical to the tv yet, but can confirm that tv sourced audio (Freesat or streamed) is perfectly in sync and delivers 5.1 when available. I’ll try direct connection from Blu Ray soon and let you know.

Possible solution:



Go to advanced settings - go to Audio Compression and set it to automatic
