Sonos beam lip sync issue

Setup the new beam today, no problem getting it working. Problem is with lip sync - I have a Samsung UHD 8000 series with Sky (in the UK). Beam is connected via ARC. Tried adjusting delay via the app and TV and can’t get it to sync, so really frustrating. Any ideas? Didn’t have this problem with the Playbar (connected via optical). Thanks Toby

    I'd like to suggest again that you take the time to give us a call so we can look into this closer.

    In the meantime, would you mind submitting a diagnostic from your Sonos system and replying back with your confirmation number while you're getting these sync issues? I'll send them up to the team to look into just in case something is being flagged there. We've seen similar issues with certain TVs not handling Dolby Digital audio quickly enough and sending it slightly delayed. If this is the case, setting to Stereo or PCM would resolve the issue, as would using an HDMI switch instead of the TV. However, this would make the CEC commands not work from Beam.

    Please note what TV model you're using here, and also, how the Beam is connected to it.

    Sonos can't give you the sound before they get it from the Samsung, so I think you're waiting on Samsung to update their software.

    I just bought the Beam and have an old Samsung TV without ARC so connected using the optical adapter. I have Sky Q connected to the TV with HDMI and had sync issue, only slightly but it was there. There is a setting on the Sky Q where you can change the delay and this cured my problem. I have set the Sky to DD too, not sure what I'm getting but it sounds great.

    Pleased you’ve found a resolution Alex. I’ve just tried it and it doesn’t work for me unfortunately.

    Also, I bought a toslink cable to test the connection via optical... but unfortunately I binned the Sonos optical adaptor that came with the Beam seeing as I was (foolishly it seems) expecting it work with hdmi-ARC right out of the box. Does anyone know the best way of getting hold of one? I’m hoping Sonos help me out here given the challenge I have with their device...

    Thanks

    Did you get a fix for this in the end? I’m about to receive a Beam, x2 play 1 for surround and the same Samsung Tv as you UE40NU7210. Wondering whether to bother unboxing them after reading all of the lip sync issues.

    I have just bought a beam and two play:1s as a surround system. I have connected the beam to my panasonic tx-40dx700b tv using the hdmi-arc connection. I have a skyQ 2tb box connected to the TV using HDMI.

    I am seeing this exact same lip sync issue. With the setup as above, when I watch to dolby 5.1 from the sky Q, I get fantastic sound from the beam, but with a delay of about half a second. No additional amount of delay can fix this! When the sky Q is set to output stereo, there is no delay.

    I get exactly the same when I connect the beam to the TV's optical output.

    If I connect the beam to directly to the sky-Q optical output, the lip-sync issue goes away, but I can then only control the volume via the sonos app on my phone, and I get no surround sound when

    Interestingly, if I watch from an app on the TV i.e. amazon prime, 5.1 on the beam works flawlessly.

    As others have said, the issue goes away when not in 5.1 mode, but then what's the point of having bought an expensive surround sound system?

    Has anyone found a solution?

    I’ve set mine up exactly the same way in the absence of a HDMI Arc port or an optical out on my old TV. I don’t get any lip sync issues but I do have the faff of having to control the volume through the app. Getting a new TV with both optical audio and HDMI arc on Wednesday so will find out if I too get the same issue.

    I have an LG tv and have mine set to Dolby Digital and managed to get the lip sync perfect using the settings. You can actually advance the digital sound output in the main sound settings on the LG’s, it’s called AV sync, mines on full advanced and it’s seems to be perfect.

    That's fascinating. Which LG model do you have? I have to wonder if "full advanced" is a synonym for "least delayed".

    Mine is about 5 years old but i go Home-Setup-sound-AV sync. Then go -5



    -5 actually puts the sound out before the picture on the tv speakers. On SPDIF -5 puts the Sonos bang on.

    Fascinating. That must mean that there's some sort of delay on processing the picture. Or maybe there's a time machine built into the TV 🙂 Delighted it works for you!
