Hi @AnnMarie66.

Thanks for reaching out and welcome to the community!

I appreciate your detailed post outlining the issue as well as the step(s) that you did, let me help and try to figure this out.

Is the audio behind or ahead of the video?

I suggest checking this article that provides steps to take if the audio coming from your Sonos home theater product is out of sync with the video.

Hopefully, that helps but if not, please submit a diagnostic report when it happens, I'd start by reviewing your system and see if there’s anything causing this issue.

I’m looking forward to assisting you further from here.

If you have any other questions or run into any issues,  please do not hesitate to reach out,  we are always here to help.

Hi I have now connected the beam to the skyq box by optical cable and it seems to have solved the problem. 
thanks
