I’m just asking if any tech experts or indeed any nontech LG owners can help.

I have an LG 2019 tv. Also an apple 4ktv and Sky Q box. I had a Beam gen 1 and now a Beam gen 2.

On receiving my Beam2 I decided to add my play 1s as surrounds. This was when the lipsync issue started, with video arriving before the audio. So audio delay settings on Sky, TV and Sonos app were ineffective. I then decided to use only LG native apps, not sky nor Apple TV. Still issue was present. 

By a process of elimination I found that there was no issue with the LG speakers - apart from the fact that they sounded hideous. The audio delay was coming from the TV - HDMI -  Beam route.

I tried all the usual things, rebooting, resetting, swapping cables, etc.

I then tried to research this through all online resources/forums etc  I could find. 

I came to 1 conclusion and 1 answer to this: 1, the conclusion, this is not that uncommon, particularly with LG, and not just Sonos. The result. One person on this site remedied it by using the LG tv Trumotion to add processing and delay to the video. I have tried this and it works. 
Which is great.

But, it means I’m adding video processing and deliberately altering the quality of the video in order to marry sound and vision.

I think it works for Sky as well, but haven’t fully investigated that yet. Apple I’ll leave for a day or two.

i dont want to lose the surround sound - it’s great. So, any thoughts? Other than Trumotion?

Any suggestions gratefully received!!
