Sonos beam lip sync issue

I am having the exact same problem. Audio is lagging behind the picture, and I can’t get it to sync at all. I have an LG oled 55 b7. Very disappointed as it seems as though this has been an issue with Sonos and Sky Q for quite a while. Wish I’d have known before spending £400!!

We'd love to look into this with you. One thing to check is that in the settings for the TV that you have Dolby Digitial selected as the audio format to go to the Beam. HDMI will usually automate that, but it's a good check to make sure you set. Also, try setting the audio source to Stereo instead and see if the lip sync improves.

We've found that some TVs have trouble processing and sending that signal on time, which can cause this, but we haven't seen the same issue so far with the Beam. We'd love to get some more details on what TV you're working with and how everything is connected. I'd suggest that you give us a call on our support line and a technician will assist with getting all the details we need to investigate and help you find a solution as well if possible.

I'm having similar lip sync issues with my Beam and certain streaming channels from an Apple 4K TV.

Is that while passing through a TV or are you sending the audio straight to the Beam using AirPlay 2?

Sending through the TV.

Ok so I changed format from bitstream to PCM and it’s a bit better. Would that make sense?

Same issues here, but turning off dolby digital in my hdpvr solves it as far as I can see.

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.

Thanks for your reply, Ryan.

My setup is a Sony X900e and an Apple 4K TV.
--On the TV, I turned off Clear Audio under Sound Settings
--On the Apple TV, I changed the Surround Setting to Stereo

So far this seems to be working; however, I'm not sure how these changes affect the sound quality.

Right the issue is fixed completely if I set sky q box to pcm or normal and not Dolby digital, using hdmi arc. Sonos customer service told me that there is no difference in the quality of the sound from DD and PCM, can anyone confirm if this is true. If PCM is worse quality than DD then I will be returning my Beam as £400 for inferior sound is a joke. Hopefully someone can put my mind at rest as I really love the beam!!!
