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?

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.

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
Most tvs have this function. https://www.samsung.com/my/support/tv-radio-video/how--to-set-up-av-sync-in-audio-setting/
Might help
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.
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.
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?
Did you try using the optical connection via the included hdmi-to-optical adapter? Might help. You won’t loose any sound quality, although you won’t have HDMI-CEC support either. On the flipside, Beam has an IR receiver and it can “learn” your TV remote, so you can control volume that way.
Where is the A/V Sync setting? I can't see it on the Sound menu.
Set your A/V sync on your tv to ON and not Auto. Lip sync problems sorted beteen tv and beam and sky Q.
Hi. I raised an issue with Samsung. I would suggest you do the same as the more people raising, the more attention it might get. I also have the retailer chasing Samsung and fortunately have the offer to return or exchange the TV.
Meanwhile, the only work around is to use PCM output instead of Dolby 5.1. Not really acceptable but at least it works!
Thanks.

Hi Mark, I’m not getting any sync issues when using the TV speakers - but not a comprehensive tests as I’ve not tried it with all channels that were causing problems before (BBC1 HD was worst I think). Have you found a fix? Samsung need to update the firmware to allow voice and video modulation as the Apple TV update provides (assuming that’s the fix).
Have you tried the TV speaker? I’ve just tried mine (no soundbar). The sound and picture are not quite in sync. It’s not as bad as with the soundbar but does seem to point to a TV issue. This is with Sky Q HDMI and optical connection to Playbar in Dolby 5.1.
Sonos - no; retailer suggested only the audio delay setting in the sonos app, which doesn’t help. Consensus seems to be that there’s latency in the audio output through hdmi-arc when using dolby, presumably due to processing, which the Sonos can’t do anything about. If the latency theory is true then I assume it can only be fixed by Samsung updating the firmware so the audio output syncs with the video. I’ve given up playing with the settings; if there’s a way to retard the video to allow the audio to catch up I’d like to know what it is.
Have Sonos offered any suggestions or do they think it is the TV?
No, my experience is the same as yours. It seems to be worse on Virgin TV than with internet VOD or streaming.
Did you fix this? I just got the Q90R ‘Flagship’. I often have negative lip sync and I can only add a positive delay. PCM doesn’t sound great. The lip sync varies so much I am changing constantly.
