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.

I took 10 minutes yesterday looking for such a device on Amazon, and could not find one.  Doesn’t mean they don’t exist, but Amazon US doesn’t seem to recognize the search terms I was using, I got a bunch of devices that can accept and pass an eARC signal, but none that could natively create that signal from an incoming HDMI input. 

I’d imagine there are some folks working on that right now, given there’s a rather pent up demand for such. It will be interesting to see what price point it comes in at, as most devices that include that type of electronics are TVs, and the opportunity for us to notice a significant price difference is low, since there’s so many other electronics in that package.  Perhaps someone like Flexson is already dealing with a purveyor that’s close to production? We just don’t know.

Here is one I found earlier on amazon

That device doesn’t create eARC, it merely passes it along when it’s connected to an eARC device that is sending it (via HDMI 1)

You’re right. Realised it today after reading up on the ARC input requirements of the Beam and Arc. What we need is a splitter that can mimic an eARC.

Hi,

 

Can B9/C9 owners confirm if audio sync is still a problem in those models? I’ve heard a firmware update fixed it. Thanks

@Marc_51, as soon as I find one, I’ll be posting it where ever I can. So far, nada. But then again, I suspect the market for such a device has increased many fold, so it would not surprise me to see something two or three months down the road. I’ll make do with HDMI-ARC for now.

I found the weirdest thing today. Whenever I watch Netflix, Disney+, etc via my Apple TV I always get lip sync issues. However, when I watch something on Apple TV+ it will stream in 5.1 DD with no lip sync whatsoever. It’s really weird. One day I’ll figure it out but I will probably have got an eARC TV by then.

I’m not sure if you mean no lip sync issues, or no lip sync.

If you set your Apple Tav’s audio settings properly, it will only send Dolby Digital audio to your TV, and the TV would then forward that to your Sonos.

That may be a moot point when Sonos releases S2, we don’t know yet, and it would also depend on your connection method. For instance, I have an optical connection, which I believe can’t carry Dolby Digital Plus anyway.

Just to clarify, my ATV is set to output DD5.1. And my beam was connected using ARC. There is a lip sync issue with all apps except the TV+, which for some reason is perfectly in sync. Just thought it was strange. When I connect to the beam using optical everything is in sync anyway.
 

I was just experimenting as I would like to go back to ARC instead of optical as it’s just messy using audio extractors and optical switches, and would save a lot of excess cables behind the tv unit.

I'm having the same issue. Just bought a new LG C7, Xbox One X. It is just terrible. You should plug in a pair of headphones into your xbox controller and you'll see just how bad it is. I haven't set up my Roku yet to see if I have the same issue, but it sounds like I will. Very disappointing. When I was playing Destiny it was crazy bad. My shots sounded like they were an echo.

Quite remarkably I came to this forum because I’ve just got a Sonos Beam with surround. An Xbox One X and noticed severe audio delay when playing Destiny. It’s unusable. However comforting to find I’m not the only one with the issue it’s exceptionally disappointing that your post was 2 years ago and the problem remains. What a shame
