Lip sync fault - Samsung QE43Q60R QLED (2019)

I have the Playbar which is only optical although I have tried a Beam and other HDMI devices. 
 

I still can't locate the A/V Sync setting mentioned above. Is it on the UK/Europe version of the Q90R TV?  

Sky Q hdmi cable direct to tv HDMI ARC,  Optical out using the hdmi and the optical adaptor for the beam direct to the beam HDMI.

Sony tv is SETTINGS > SOUND > Then look for the A.V Sync.  If it is set to Auto move it to ON. This removes the lip sync issues.  Sorry dont know where it is on all TVs but check it out.

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. 

Most tvs have this function.  https://www.samsung.com/my/support/tv-radio-video/how--to-set-up-av-sync-in-audio-setting/

Ive been suffering with lip sync since i purchased the sonos beam ive tried all sorts off setups but nothing sorts it 

Samsung say its sonos problem 

My tv IS  a QE55Q8CNA any help appreciated 

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.

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

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

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.
