Lip sync fault - Samsung QE43Q60R QLED (2019)


The Beam has lip sync problems with the new 43’ QLED TV when audio is delivered to it in dolby. No sync error with PCM.

From a cursory reading on here it seems Samsungs generally work with Sonos (ie without sync errors).

Other than adjusting to PCM are there other settings I could adjust to retain dolby while eliminating the delay?

@Jonjon1239  This may be a possibility, albeit it’s expensive.

I'm having a similar issue with my 2019 Q85R where when I'm playing my PS4 or Xbox One X there's a delay between actions and sound. It's fine when watching Freesat or the inbuilt apps but I game quite regularly and it was really distracting when playing The Last of Us Part 2.

 

I have a 5.0 set up with a Beam and 2x Sonos Surrounds. I'm connected via HDMI ARC and I can't really use the optical solution from console straight to Beam as I'll have to swap it constantly which will be fiddly.

Is there any way I can possibly get around this?

Audio Lag Solution:

I now have the Cablebox to TV as HDMI for video. And discovered there is a Optical Output from the Cablebox which I used with Optical/HDMI adapter to run directly into the Beam. I'm going to get a 3-1 Optical adapter to ultimately connect all audio components including TV apps, BlueRay, and Cablebox.

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.  

Now got to decide if I want to upgrade to the Sonos Arc.   I know I won’t probably get Atmos,  but oddly, my TV settings have a selection for that.  But I wonder if the sound stage is better than the Beam   

I was having lip syncing problems with Sonos Playbar and my Dish. Found out that if I turned off the Dolby on the Television I can now go direct from the Sonos to the TV and I have no problems with the Delayed lips sync Using either the Dish, Streaming services, or the DVD player. They are all 3 in harmony.:relaxed:

Here are two videos to help with testing.  Play these on the TV in the YouTube app.

 

That’s interesting, and suggests two different paths in the TV for the audio from each source.

Also, just for clarification, by using the Optical from the TV, I was also able to use the TV apps without the lag.  I still found a slight delay for tv broadcasts. 

I’d concur with MSterling. The issue is the inability of the TV to pass the signal back out to the Sonos quickly enough to avoid lip sync problems. Pulling the audio out before it reaches the TV is, until Samsung can affect an appropriate fix, the easiest and least expensive way to resolve the issue.

Please see my above response.  Also, please refer to my other replies on this subject.

The answer is not great, but it is a solution.

Got exactly the same issue.

 

Just bought the QE65Q90R. At the same time, I also bought two Sonos Play 1s to add to my Sonos Play Bar to great surround sound.

 

Switching to PCM defeats the object of the surround sound.

 

Is there any other solution?

Thanks, Samsung have sent out an engineer (3 visits) who have reported back that there  appears to be a compatibly issue with the soundbar.

 

I have chamged the settings on the tv to PCM and the sound sync is fine, I will now go back to Samsung regarding the TV processor .

 

Thanks

I have the same problem, please see me other replies.  I was able to use the optical output off the DVR, and also the optical from the TV for the TV apps, and the voice lag went away.  I utilized a J-TechDigital optical switch to control the input.  I realized this does not “solve” the TV problem.  But I like the Samsung Q80 75” that I bought, and this adapter solves the lag.  If I see a firmware update, which I don’t expect to the TV, that resolves this I’ll reconsider my need for the adapter, but for about $30 for adapter and cables - problem resolved.

I have a  2019 Samsung Q7 which I purchased direct from Samsung and have been complaining to them since I purchased it, I have sky Q connected via HDMI and playbar connected via optical cable.

When I switch the optical cable to Sky Q to Soundbar there is no lip sync issue but I cant use TV apps 

 Samsung have sent me firmware update and last week replaced the motherboard, neither sorted the issue as I need a negative adjustment on the sound. 

I am now advised that there is a compatibility issue with the sound bar and this is not Samsung’s fault., I am continuing to press them for a full refund.

 

Any assistance or advise would be greatly appreciated as this is driving me insane. 

It sounds like a case of the TV processor is ‘maybe’ not operating quickly enough to send the Dolby surround audio out its port to the ‘Receiver’. Some brands/models of TV still seem to have this issue as the manufacturers tend to spend more on the display/picture quality perhaps, rather than improving internal components for audio. TV speaker quality on some brands are testament to that. 

There is little that can be done for the in-built TV Apps in this type of case, but a separate audio extractor/splitter will at least work in most circumstances for external components, like Sky Q boxes, Apple TV’s etc. Fortunately most of those products now have the majority of useful A/V Apps, like Netflix, Amazon Prime Movies, YouTube, Spotify etc; just to name a few of the popular ones.

You say you have ‘now been advised that there is a compatibility issue with the soundbar’ but it’s unclear from where you have obtained that information, what is the source? and is the compatibility issue merely the case that your TV cannot process the audio quickly enough through its own port? If that is the case, you may need to approach customer care at Samsung and discuss the matter with them further, rather than with a Sonos user community here, which will likely show some bias towards and in favour of the Sonos product. It’s a Speaker after all and so the PlayBar will only play the audio when it gets it and clearly in your case the PlayBar sounds like it is getting it later, rather than sooner. That infers it’s a TV issue.

One thing you may want to try is switching off any audio enhancement features on the TV itself and perhaps even try PCM stereo audio output from the TV instead, just to see if the TV processor can send that signal quickly enough for the A/V to be in lip-sync and if it does work for you, it may go some way to point toward the TV processor being too slow for managing surround sound.

Hope that assists.👍

Pretty clear indication the delay is being caused in the TV?

Absolutely.

With the concept that misery loves company (not sure that really true).   I can confirm the same problem on my 2019 Q80 (U.S. version).  When I have Xfinity set to Stereo no issues.  But when set to Dolby 5.1 it has the video ahead of audio sync problem.   I have one more item to throw in the mix.  

 

My Xfinity X1 box HDMI Out is sent to my Denon AVR HDMI input.  Then the Denon HDMI out feeds the Samsung HDMI input.  And lastly the Samsung HDMI ARC feeds the Sonos Beam.  I have the Denon set to HDMI Pass-Through for when it’s not active and in Standby mode.   I have the Denon in the mix, because I also use it to play music to on my B side connections to my patio.  I use the Xfinity Music channels for that at times.  

 

I have not yet experimented if removing the Denon from the path of connections would rectify the lag problem.  But based on my reading of others, I don’t think this will help.  I have yet to try  +Firestarter999 usage of the Optical.  But I really didn’t want to give up the HDMI-CEC function of having one remote from Xfinity to both control volume and power on/off the set.

 

Lastly, I acquired two Sonos One’s a few days after getting the Beam, and successfully connected them as Left/Right Surrounds to the Beam.  With Xfinity set to Stereo, I hear audio for through the Ones’. Although, it’s not clear to me if they’re acting as Surrounds.  I don’t have the Sub.  So my set-up is 5.0.

Can someone provide guidance on this last comment?

Thank you.

I raised it with samsung and they are adamant it is a sonos problem after going  back and forward emailing swapping settings

On the Q90R Samsung UK have been able to reproduce the lip sync issue and have passed it to HQ for further analysis.

If the video is ahead of the sound then I’d expect it to be a TV issue. If the sound is ahead of the video just use the delay settings to correct it. 
 

For video ahead of sound all you can do is raise it with Samsung and escalate the issue. You can contact the CEO from their website. The more people that do this the more chance we have of a fix. I raised for Q90R.

Well this thread was for Samsung TV issues so thanks but I don't think we’ll find the same settings on the Samsung as you have on the Sony.
