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.
Not much point if I bought the arc for Dolby Atmos!
^ 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 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.
Does your tv have eARC? I have read elsewhere that there are well known issues with lip sync and sky q over hdmi. I have no lip sync issues at all with my Xbox one - LG C9 - Arc setup. All internal Tv apps are spot on.
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.
Could you confirm what all the connections are in your setup. What are the sources (clearly ATV is one)?
BTW we used to fix lipsnyc issues with data compression whether it was compressing or not compressing the data - however that doesn’t fix the issue on the ARC
Hello all. Seems like this is the most current chat on the audio sync issue with the ARC. Not trying to hijack the thread, but just keep a current single documented conversation.
I have a new setup with an existing Sony XBR TV and a new ARC, Sub and two Sonos One’s. I am also getting the lip sync issues with every source I have tried- Apple TV, Xfinity boxes, and in TV apps like YouTube TV. I first thought it was a YouTube issue until I saw it in the Xfinity Flex box, then the Apple TV. I also have tried the optical adapter with no luck and I’ve been exclusively using the Sonos cable. I haven’t submitted a diagnostic yet, I will do so tomorrow. What is bad is that Sonos says if the audio lags the video, which it does, they have no solution.
And now for the worst part- I used the Sonos trade-in program at Best Buy to upgrade older Sonos pieces. Now I’m seriously thinking I need to return this kit if I cannot find an acceptable solution. But, then I don’t have my old products back in return. So what is the Sonos solution for this? If I return the ARC, et al, I then have nothing.

Hi
Thank you for a very detailed response. I could not agree with your point enough.
I would be morethan happy to send this to our engineering team as a feature request. However, Just to set your expectation you will not be notified but what we can do is to subscribe to this thread and check our announcement from time to time for any updates or accessory release just in case we have anything that may relate to this concern since Sonos were made to serve only (one master) to which ever it is plugged into via either the optical cable or HDMI cable. This is a good point as well either to release an update for a little HDMI hub exclusive for Sonos devices as well an a mini switch on the app for the Sonos device to switch from any HDMI option input option on the Sonos app as this can be quite impossible to be done automatically if for example both the TV and a cable box feeds the same signal going through the hub,
Please let me know if you still have further questions or concerns.
Hi
Welcome to the Sonos community. Thanks for reaching out to us.
I would like to clarify that Dolby Atmos is only available to the Sonos Arc and having this feature on the Sonos Arc does not translate all video coming from the TV or from any other source to generate Dolby Atmos unles we can verify that the audio we have on the TV is encoded with Dobly Atmos. Everything still depends on how the video is coded and what signal does the TV receive and generates towards the Sonos Arc.
However for the Lipsync issue, I would like to recommend 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 have already returned the arc and gone back to the playbar with no issues.
