Sorry but you will have Lip Sync issues if connecting to the Beam via Arc from a Samsung TV. I do with a Q90r. 

Thanks Viper - can I use an optical cable?

Any other solutions to prevent Lip Sync issues?

@Simon B Following Viper’s response - where he clearly has a problem with Lip Sync issues with Samsung and the Beam - do you/ Sonos have a response?

Hi @Cloud24, thanks for the update. About your question, you can try to use the optical cable.and for us to check the status of your Sonos system, I’ll ask you to submit a diagnostic report to investigate further what could be causing this issue.

Yeah I currently use an optical cable from my different equipment to an optical switch and then pass that to the Beam via its adapter. Only issue is that optical is being phased out on newer equipment for example the PS5 and Series X so this may well have Lip Sync issues when you use HDMI.Would be good if SONOS could update the Beam to have EARC as this is supposed to eliminate Lip Sync issues on TVs that support (2020 Samsung's)  although not sure if there are technical reasons why this hasn't been done.

Hi Simon B,

I am having lip sync issues between Beam and Samsung TV (HDMI ARC). It’s particularly bad when watching UHD through Sky Q. 
 

I have submitted diagnostics through the app, confirmation number 1036884174.

what can i do to sort this? It’s a 2020 Samsung TV. 

Hi there @ds6g09, Thanks for reaching out, and welcome to the community. Sorry to hear about this sync issue on your Sonos Beam and Samsung TV. Thanks for sending a diagnostic report of your Sonos system, upon checking, no issue was detected on your system. But kindly check this article about TV audio and video are out of sync and check if that will work for this issue.
