I THINK THE PROBLEM IS A BUG IN THE SKY Q uhd BOXES

Sky needs to fix this issue NOW!!!

I have exactly the same issue! The phone engineer managed to loose all of my sound so I was stuck without any, then it just came back and youtu.be was fine for a week and now it's started going off again on YouTube! What can I do???

When my case happened, I called sky and they changed my sky Q to the 2TB box which they said did not have the problem.
