So, my previous setup was a 6 year old Samsung TV connected to a Sonos Beam Gen with inputs from a PS4 and Sky Q. I managed to get round lip sync issues using a Toslink adapter.
I recently updated to a Samsung QE55Q7F2AUXXU, and a Sonos Beam Gen 2 with the same two input devices. I found that the lip sync issue was present on this device too. It is worth stating that this TV doesn’t have an Optical Port despite the manual stating differently.
I searched online for a solution, and despite changing settings on the TV, Sky Q, and the PS4 (DVDs and BluRays), I still experienced lip sync issues. I purchased a couple of HDMI audio extractors and whilst the lip sync issue was resolved, I lost some functionality with the TV remote because the Beam wasn’t recognised as a fully connected audio device.
I then decided to do a little more research and after some trial and error, I have resolved the issue without the need for any other technology.
It turns out that after you’ve selected all the relevant settings, you then need to unplug all devices for a minimum of 30 seconds, then turn them on in the following order - TV, Input devices, then the Sonos Beam.
I hope this helps other users to resolve this very frustrating issue.
