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.

Hmmm, this has me rethinking my Sonos Arc preorder.  My second choice is the Sennheiser Ambeo, but those can develop a glaring problem over time (center channel becomes muffled for some reason).  It’s also around three times more expensive than the Sonos Arc.

 

Only reason I’m trying to replace my 3.1 system is I want Dolby Atmos when watching all this new Dolby Atmos content and I cannot add separate Atmos and rear speakers.

I did find switching the video mode to Gaming helped quite a bit. The less processing the screen has to due the less latency.

I have been tinkering with settings for over a year and still having issues...I’m ready to try the audio extractor. I have an LG B7 OLED, Apple TV 4K and playbar. Obviously, I don’t want to lose 4K or HDR. What is everyone’s thoughts on this?

There is also a 4K Arc version as well, should I need that?  I was just thinking I’d run Apple TV to the extractor. HDMI from Extractor to TV and optical output from extractor to HDMI. 
 

Thoughts?

Hi All,

 

I have a LGC7 OLed, Sky Q, ATV and a Sonos Beam. I had the much talked about lip sync issue when using sky Q. I fixed this by using an Optical switcher. I am interested in the new Sonos Arc sound bar and want to ask if anyone has had lip sync issues with it and Sky Q so far? I know I could use the HDMI / optical converter like I do for the beam but then I would lose Atmos. I would also use it with ATV and an xbox one X as well.

 

I assume that the C7 that has Arc but not eArc will output Atmos.

thanks for any advice

 

Josh

Do you have any addition source devices other than the ATV?  If so, you may want to find one with more HDMI inputs.  I bought a product from J-Tech that’s also a good brand.

No - just the Apple TV. That said, the ARC version also has more inputs as well. Not sure if I need that or not...

I did some additional browsing of this Orei.  You may want to check their web site directly for other related products that I did not see on Amazon.  I’m not sure if they are new models with more features.  Please let me know how this goes, because I bought a Optical In (3) to Opital Out (1). (which uses the Optical to HDMI adapter for my Beam.  I am interested in knowing if what you considering will work and also pass the DD+, which the Optical does not. 

My Sonos Beam still has a lip-sync delay and i’m now considering an optical switch as many have said this solves the problem. 

 

How does this work exactly - i have searched you tube and can’t see anyone giving instructions to complete novices as to how to set this up. Have i got this right 

 

Tv’s Arc hdmi to the switch’s hdmi slot that says ‘out’ 

Optical adapter supplied by sonos into the slot that says toslink and then back into the beam.

 

Will that then get rid of the lip sync?

 

If i then put an amazon fire stick into one of the switchers hdmi ports would the sound play through that hdmi channel?

 

It all seems very confusing - i love the sound of sonos but the audio delays are maddening.

 

Any advice would be appreciated.

 

This is the switch that has been recommended.

It's absolutely disgusting hat 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.

I have two beams. Connected to both LG and Samsung TV’s. The sync issue is bad on both. Shocking for the money you pay.

After many months on the Optical I tried the HDMI ARC port again.  Lo and behold, it’s not giving the audio delay.  I keep track of the firmware updates on the TV and maybe the the S2 update to Beam did something - no idea.  But here’s one odd thing, the audio was now slightly faster than the video.  Almost imperceptible.  So using the TV Sound/Expert settings, I added a slight delay.  

FYI: This is on a Samsung 2019 75” Q80R

Hi mate I'm in the same boat as you with the Firestick and a Panasonic TV.  Netflix works fine with stereo 2.0 but sound delay on Dolby settings for 5.1.  did you try the switch from Amazon?

The built in TV Netflix app seems to work ok.  But ide rather use the Firestick! So annoying!

The delay is BACK!!.    It appears the Xfinity box as a HDMI source is definitely worse than the in-TV apps, which is pratically perfect.  I also put a 18gbps HDMI cable on the Xfinity to TV connection and that didn’t seem to help.  I did try a high-speed HDMI cable with Ethernet for the HDMI-ARC to Sonos.  It’s better than the Sonos included cable but still annoying.  I’ll be probably switching back to the Optical which at least does not pose that problem.
