Hi I’ve got the new Sonos arc and it’s connected to my Samsung Q90R tv via the arc HDMI, my TV viewing is with Sky Q 2tb box. I’m getting lip sync issues being slightly out, I have adjusted the audio settings to zero on my sky box TV and Sonos app but still no joy. I had the playbar before with no problems any help pleased.
Hi All,
I had massive issues with Lip sync and they now seem to be solved.
My Setup is a Sonos Arc plugged into the E-ARC HDMI port on a Samsung QE85Q70T. I also have a NVidia Shield Pro running Plex plugged into the TV via a HDMI port.
My Audio sync issues were much more prominent on the Netflix and Plex on the Nvidia shield.
My fix was as follows:
My issues now seems to be resolved including for True HD 7.1 Atmos Blueray rips on Plex.
.
Hope this helps someone.
Thank you! We switched our projector to a Samsung one and suddenly started getting lip sync issues with the Arc. Your Samsung TV settings worked perfectly for our projector too. Thank you!
Okay
It hadn't crossed my mind that I'd need to buy another device to get premium brand and model TV and soundbar playing well together.
The pass through setting on the LG TV definitely made the biggest improvement to the audio sync. Not sure if any of the other settings on the TV have helped.
It’s difficult for me to comment on your particular hardware, as mine is different. I use the Sonos Arc with ‘Fives’ and two Subs that are connected to the older LG C9 OLED TV via eARC (set to pass-through). I use FireTV, Nvidia Shield & Apple TV with no lip-sync issues seen.
In my Dining Room however, I have an older LG TV (2015) which has no eARC, just ARC, and supports DD 5.1 and that had very slight lip-sync issues, even on pass-through, with a Sonos Beam (gen2). Anyhow I chose the Feintech audio-splitter/extractor and that solved all the lip-sync issues and gave me Dolby Atmos on that TV too, but again I use the Nvidia Shield (mostly) with that TV. So that was my reasons for suggesting an audio extractor and perhaps try bypassing the TV altogether. It worked in my case, but obviously it’s different hardware to what you are using.

Came here to see if Sonos Arc users are getting audio sync issues as I'm having this issue with my Vizio Elevate soundbar connected to LG C1 TV, Google Chromecast TV, and Xbox series X.
The Elevate has 2 HDMI inputs which resolves audio sync but the Elevates HDMI ports do not support 120hz refresh rate of the Xbox. Major bummer because it's one of the reasons to own a next gen gaming console.
With devices plugged into the TV and eARC to soundbar, the lip sync is super obvious when playing Dolby Atmos content. I've tweaked the pass through and other audio processing setting on the TV but there's still sync issues. The Elevate Audio delay setting is also one way.
Is this just a universal issue for soundbars even when connected to eARC supporting TVs? I've also tried this same setup on a Samsung Q70 tv which also produced audio sync.
Do I just need to get lucky with the right TV, soundbar, and streaming device setup? I'm starting to think that there will also be some delay and perhaps some people just don't notice or care. Is the only solution to get a soundbar with HDMI ports that support 120hz refresh rate?
Have you maybe considered bypassing your TV altogether with an audio extractor, such as the HDFury Arcana or a Feintech VAX04101A? There’s nothing to then process the audio and slow it down, although I would have thought your LG CX TV set to ‘pass-through’ should have achieved that for you anyway.

Depends on what the word ‘mini’ means in this case. You’ve essentially got two soundbars available, I recommend each mostly by the size of the TV set in use. If the TV is 50 inches or less, go with a Beam. If the TV is larger than 50 inches, go with the Arc. In either case, fill out the ‘room’ with a pair of One SL speakers to use as surrounds, and a subwoofer to support the movies/TV shows you watch.
Is there any Pro Person who can Give me the Ideas and Best Design for making a New mini Home Theater on my own house. I Will Be Very Grateful for your Opinion and Work.
I had just the same problem
I have Sky Q 2tb linked via TV (ARC) to Sonos ARC.
Tried everything in the settings of TV and Sky but no improvement.
Solution download latest version of Sky Q software and let the system update. PROBLEM GONE !
Word of warning… updating the Sky Q box means you will need to relink any Sky mini boxes you have and also relink their remotes to the TVs.
I guess if i had thought that I wouldn’t have asked the question! But, now you’ve said it it does make sense.
However, there was a reason for my ‘illogical’ thought process, and that was because I changed audio mode on my TV from ‘Dolby Digital Plus’ to ‘Pass Through’. I was thinking DD+ would provide better quality. But, not being overly savvy in this area I didn’t realise that that option was processing the sound in the TV before transmitting to ARC.
So despite me feeling that your response was somewhat patronising, you have at least helped me to understand the setup a little better. So thanks.

You state: “I thought this was going to cause issues with receiving the correctly decoded sound, but I can confirm that when I check the app I am still receving Atmos or 5.1 where it is available. Although I would be interested to know if this option has an impact on the quality of the sound signal being processed…?”
You might think when a setting is called “pass through” no decoding is done at by the TV all, because the stream originating from your source is being passed through. The chance of deteriorating sound quality, if that's what you're afraid of, would be less, not more.
I would like to confirm that thanks to this thread, I appear to have fixed my lip sync issues by selecting the Audio Pass Through on my Tv’s audio settings. My TV is a Hisense U7G.
I thought this was going to cause issues with receiving the correctly decoded sound, but I can confirm that when I check the app I am still receving Atmos or 5.1 where it is available. Although I would be interested to know if this option has an impact on the quality of the sound signal being processed…?
When I did have the issues, I found them to be more evident when using an external source e.g. chromecast, that provided the signal to the TV
I fear though that I am just one of the fortunate ones because my TV has this setting. It seems incredulous to me that so many people are have the same issue. It does make me wonder how much testing was done, and on how many different types of TVs…!
For anyone else who does not have the ‘pass through’ option, I have read and tried out the work around to switch on the motion-smoothing option your TV has. This apparently creates a slight video delay which may counter the delay you experience. I did find this worked for me to a degree.
Sonos can only play the signal as quickly as it is provided it.
Sorry if this has been said, but the solution is obvious, but not trivial. TV manufacturers should allow configurable picture delay.
Not letting Sonos off the hook, but logic dictates that the onus of processing delays lies on the eArc processor (e.g., the TV), not any sound system.
In a fantasy world, processing power would obviate this need, but we know that won't happen soon, if ever.
Could you confirm what all the connections are in your setup. What are the sources (clearly ATV is one)?
Sure, I have ATV and a BR which goes in to a Hd Fury Vertex 2, then that goes in to Hd Fury Arcana. The arcana splits and eArc goes to Sonos Arc and video goes to Epson. The lip sync issue seems to be that the video is ever so slightly ahead of the audio. Just enough to be annoying. I have tried resetting and unplugging anything but no luck.
Could you confirm what all the connections are in your setup. What are the sources (clearly ATV is one)?
Yes video ahead of audio. I can’t figure it out. All was until about 3 or 4 months ago and then something happened. I suspect it is on the ATV side but even though I run the wireless sync option it doesn’t change anything, even if I run it in different frame rates. I’m going to test today with an old BR player and see if can isolate the issue but so far no luck.
So just tested with BR file and the delay is the same. So now I know it is not ATV but somewhere in the Vertex 2 > Arcana > projector / Sonos side.

I am with Ken on this. The issue for me happened before it even got the the Sonos Arc. I still think the ability to have a negative and positive sync adjustment is the simple way forward.
this makes so much sense. My video is ahead of audio for some reason. I have Arcana and a projector. So annoying to not be able to get it in sync.

Yep tried all of the correct procedures but no joy, contacted Samsung who’s reply was it’s a Sonos problem. If I can’t find a solution I will be returning the arc.
If you do not have eArc on your TV or have lip sync problems, here is the solution. An adapter that sits between video source and Sonos arc! it's time for Sonos to start promoting this product, for your own sake. https://www.hdfury.com/product/4k-arcana-18gbps/
I have the same issue with a Philips OLED TV. I complained to Sonos & Philips. Sonos said it was the TV. Philips sent me an upgraded TV but the issue remains. Sonos say it is the TV that is the causing the issue when trying to process the 5.1 signal. My workaround is an optical splitter which isn’t ideal. They say TV’s with eARC are preferable but I don’t know if that’s true. I have a Sonos Beam. Does the Playbar have the same issues?
Would the HDFury solve my issues?
I am contemplating asking Philips to take the TV back and I will get another TV (with eARC). But reading the forums I may get another make TV with the same issue. So frustrating.

Hi there,
I’m also having issues with the lip sync lag. I just purchased the Sonos Arc to create a home cinema in combination with the LG Largo Cinembeam (with ARC HDMI input). Loving this projector, by the way.
Ok, so - I am using the Sonos Arc HDMI cable supplied. I purchased the Sonos Arc for the Atmos capability, so I’m bummed that the only options after reading the threads seem to be:
1) Use an Optical cable and then not make use of Atmos, which is a major characteristic of this soundbar,
2) Live with the annoying sync lag,
3) Send the object back,
4) While it’s a workaround, I don’t think it’s acceptable for Sonos Arc users to throw another 200 euros on a third party product switch/splitter to fix this issue/potential flauw. Adding the extra device undermines the intended simplicity of the object, as the big draw is to have a simulated surround experience in one clean beautiful object.
I’ve had a Sonos Playbar for many years and that works perfectly for my Samsung TV.
Sonos: will there be a firmware update to occur to fix this shortly - shortly being the 30 day return period? If the issue is inherent to the Sonos Arc, then it would be logical for Sonos to fix this issue of their top-of-the-line Soundbar.
I just can’t see how Sonos can fix a delay in receiving the processed audio - the Arc plays it as soon as it arrives, with virtually little or no buffering involved and no transcoding. The issue is what is happening to the audio before it arrives at the Arc that is causing the delays and lip-sync issues.
The HDFury Arcana, or other audio extractor/pass-through devices, are often there to bypass some TV’s that cannot either handle or process the required audio quickly enough through its ports… so this is not actually a Sonos Arc issue, it’s the sending device, or a device situated enroute to the Receiver … a good many TV’s work okay, so that in itself perhaps shows where the issues really lie here.

^ Thanks, I had heard something about this pass through. I have checked the XF90 and cannot see this as an option on my TV within the menu structure.
I understand LG use ‘pass-through’ and they also have a lip-sync adjustment feature within the settings on some of their latest TV’s:
