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.
Hi,
I have the exact same problem ( Paul A Please note )
I bought the Samsung Q90r to use with my Beam and 2 x 1 surrounds. I was hoping to next upgrade the Beam by purchasing the Arc.
The problem is not cable related as I understand it but is due to the TV’s inability to pass through 5.1 digital audio fast enough to maintain lip sync plus the fact that the Beam and the Arc have only one input so that the digital feed cannot go from the SKYQ box into Sonos soundbars first and then proceed to the TV ( as is common with most high end soundbars and AV amplifiers )
PCM stereo can be fed into the TV direct from SKYQ and there will be no lip sync problems when passed through from TV to soundbar but that setting is just vanilla stereo.
With the Beam you can get round the problem by using optical cables from SKY, TV, and XBox etc and by using an optical switch to independently feed 5.1 surround from each device direct to the Beam.
You can also do the same with the Arc but what you can’t do specifically with the Arc is utilise Dolby Atmos as optical cable can’t carry the Atmos signal. Dolby Atmos requires the use of arc or earc HDMI direct from source to Soundbar. There are currently no HDMI arc/earc switch boxes although HDFury are currently developing one.
So currently the options are
Feed SKYQ into TV with a SKYQ set to PCM and you can get Dolby Atmos from the TV apps and stereo from SKYQ using the Samsung’s passthrough.
Or use optical cable and optical switch box to get 5.1 digital from TV and SKYQ but no Dolby Atmos.
Or use the arc port on the TV for TV apps ( Amazon/Netflix ) and unplug the HDMI arc cable from the Soundbar and plug in the SKYQ optical cable ( with Sonos optical/HDMI adapter ) when you want to use SKYQ.
Samsung were wrong to say it’s a Sonos problem. The Samsung TV doesn’t passthrough Dolby Digital signals with correct lip sync. Video is ahead of audio and can’t be adjusted.
However I do think that Sonos made a big mistake with their Arc soundbar in only having one port. This high price Dolby Atmos soundbar should have have had several input ports and arc HDMI to allow for direct input from several devices that potential customers are very likely to have and that would eradicate any lip sync problem.
If HDFury succeed in making a suitable HDMI arc switch box the problem is solved ( though not inexpensively )
I would think it would be in Sonos’ interest to look into developing their own HDMI arc switch box or by bringing out an Arc Mark II soundbar with sufficient ports to cater for satellite/ cable, Xboxes etc
I intended to buy an Arc soundbar but for now though “I’m out”.
BTW the Beam plus 2 x Ones surround speakers sounds superb
SKQ
Bluray
Samsung Q90r TV
Inexpensive 3 way optical switch box with remote
Dolby 5.1 surround from all sources

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.
been a Sonos dealer since 2007 and I can tell you the ARC sound bar has a lot of problems. I noticed the lipsync issue with Samsung TV too and also have noticed with Samsung TV when you play music not the Arc and then trying to go back to TV it will tell you it cannot connect. What I do to fix that issue is simple turn off the TV and then change the input to TV and then put the TV back on. BTW I find it disingenuous when Sonos reps post and tell us they don’t know what we are talking about for they knew very well whats going on. BTW the sound on the ARC soundbar is not as good as the Playbar for me anyways. And why did they put the volume and pause button on the top of the ARC soundbar when most mount then really really close to the TV (sometimes even touching)
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.
Just out of interest, those of you who have upgraded from another Sonos product to the ARC and then suffered lip-sync issues, what was the other product, did it work without lip sync and what was the sound like compared to the ARC please?
I have the same issues. I have written to my retailer to kick off a support query, but, I want to be ready to send the ARC back and swap to a previous Sonos product, hence the questions above.
Thanks, Dave
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.

Hi
Thanks for the immediate response and feedback.
I want to share to you a link that might help. I may seem that you have the same issue and almost the same TV.
Here;s the link and here’s what happened.
If the issue still persist, Please submit a diagnostic while you have the issue on-going and here’s how. I’ll be more happy to take a look at it for you.
Thanks,
I have the same problem with a new LG TV, sky, ARC.
It is beyond me how after such long product development, and with such a standard (at least in the UK) they cant sort this out.
I think Im going to have to return my Arc as well.

HI
Thanks for the immediate response.
Can we also try to reboot the TV and the Sonos Arc, unplug both from power and plug them back after 10 to 15 seconds.
Can we also try to unplug and plug back the HDMI cable from the ARC and from the back of the TV.
Then can we also observe and check if the issue is still re-occuring.
Can you please try to submit a diagnostic and here’s how (while there is audio coming out of the arc), so we can further check what could possibly be causing this audio delay.
Please let me know how it goes.
Thanks,

HI
I would like to share to you the information provided on the diagnostics. It seems that your Sonos Arc is receiving intermittent signal connection from the TV,
You may want to double check the HDMI cable and make sure they are fitted snug at the back of the TV and at the back of the Arc.
Please let me know what the outcome is.
Thanks,
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 have recently purchased the Philips805 and Sonos Arc. The TV apps work perfectly with the TV and sound bar, I am getting Atmos DD+ which is great on Netflix. 5.1 and other formats also all work perfectly whilst watching the streaming apps. Now here is where the problem starts. When watching TV via my V6 Box I get lip sync issues with all 2.1 and 5.1 TV shows/films etc. Stereo works perfectly fine and last night I surprised to see I had no issues when watching BT Ultimate, which gave me Atmos DD+.
The only way around is to connect the optical cable to the from the V6 Box to the Arc. This way fixes all the lip sync issues with 2.1 and 5.1, but I then lose all sound on the TV apps such as Netflix, Prime etc and also lose Atmos DD+ on BT Ultimate. I don't mind changing the cables in the Sonos Arc short term, but I want a long term fix. I brought the Arc to keep things simple and clean, I love the sound but not the faff it is causing. I never experienced these problems on my previous set up.
I am also having the same issue with my brand new Sonos Arc and new Sony Bravia XH90 TV. It is really upsetting having spent so much money and then to have these lip sync issues. In TV Apps work fine but there is a noticeable lag when watching from my Virgin box. I would not have cashed out on a Sonos setup had I known this issue was going to occur. Also frustrating that older Sonos products will not work on the new S2 App. Seems like a money making exercise to me.
As others have mentioned, the HD Fury Arcana is being mooted as the solution, allowing external devices such as SKY/VM boxes to bypass the TV and direct sound straight to the soundbar. I really think that Sonos need to release a similar device free of charge to us.
^ 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:

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.
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.

I am having the same audio delay issues with Arc. I have an LG B8 Tv, AppleTV 4k. all audio processing is turned off and set to bypass. I have a noticeable delay, especially on Atmos content. Tried everything. It’s very difficult to tell if its the TV or the Sonos. I previously had a Sonos Beam connected to the same TV and had no issues.
Ok so let me get this straight this a premium soundbar that cost $1000 has audio delay issues and no 2.1 HDMI pass through on the soundbar?! What idiot thought that would be great idea? I was going to pick this up, but not now, I also smell a class action law suit because the product is obviously broken and cost is premium and maybe you can get away without the 2.1 HDMI pass through, but those audio sync issues are a problem and at that price Sonos is basically stealing people’s money for a broken product this just absolutely disgusting business practices.
Sonos can only play the signal as quickly as it is provided it.
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/
