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.

It's absolutely disgusting that between LG especially and Sonos that this hasn't been worked out. This is all very expensive equipment that people work hard to pay for, and you get two products which cant even get something so fundamental like Lip Sync right?

I keep checking for a class action lawsuit to be started against LG. Their frontline staff are absolutely useless and just knowingly make things up to get people off the phone. Don't underestimate their desire to wear everyone out until the issue just stops being talked about and we just forget we are using stereo on our TV's instead of Dolby.

As for Sonos, get with the last decade and put a darn HDMI Port on your Playbar and Playbase. HDMI ARC would have solved this whole issue.

100% agree but I don’t think it’s a Sonos issue personally. I think it’s LG. It’s works perfect over optical only. So it’s something to do with the HDMI pass through ability of LG TV’s. I am not sure if a HDMI port would help. We’ll see if anyone reports issues with Beam.

Hi all,
As predicted by some on here, the main board replacement had no tangible effect on the lip sync issue. The engineer has escalated this with his base, who will advise LG of the outcome. Hopefully another voice to a growing chorus of discontent at the contempt LG are displaying towards their customers.

LG just take the p**s they really do. I work as frontline IT Support for a major tech company and I wouldn't have a job if I behaved the way the clowns at LG do.

They really just have no care about wasting people's time with things they must know wont fix anything, just to wear them down. I really think for the amount of money we pay, someone high up at Sonos should be our advocate with this. It will mean more to LG coming from Sonos.

So is it safe to say if you have an OLED television stay away from Sonos for now for home theater? I guess we don't know on the beam yet but that seems more like a bedroom speaker then main room..

I think the beam looks great (Aside from lack of HDMI Passthrough). It's probably worth seeing how the reviews stack up against the Playbar when it is actually released.

Sonos could make the Beam far more attractive to home theatre users if they allowed us to use it as a centre channel with 2 other Sonos units as front left and right speakers. Now that would be amazing!

I just hope the beam doesn't suffer from audio delay, it's a deal breaker if so.. as far as the beam as a center channel I agree that would be amazing but they didn't release it that way and seems unlikely that things will change.

As has been stated before, the delay is within the TV, and not the BEAM. And it's not a center channel only, it's the center, left and right in a single enclosure.

Where did any of us say the delay wasn't in the TV? From many reports online, it is stated the issue is with the TV Optical port though, so many of us are hoping the Beam having a HDMI port wont suffer from the same problem due to being connected to the TV via ARC.

Also, no-one said the beam is a centre channel only. Just that it would be good to be able to use it that way with 2 other separate sonos speakers as front left and right. This is purely a suggestion to Sonos.

Sorry, I was responding to the statement "I just hope the beam doesn't suffer from audio delay,", but you do have a point, assuming that you're connecting with the HDMI cable rather than the optical cable. I would expect that if it was connected with the optical cable, it would have the same delay.

I'd be fascinated to hear from someone who can test this.
