Sound cuts out when using spotify or you tube

I have 2 screens - one has cb - the other is either you tube or spotify. If I am recording audio and click to play the video on either you tube or spotify then the sound cuts out on cb. when i place the mouse back on the cb screen and click the sound comes up. Any ideas please? ta

Thanks Steve…it was ticked.

It won’t work as Cubase is not in the background when you click on it. Unless you have a multi client driver which most audio interface don’t have you can’t do this. Some use asio4all to achieve it but it’s a bit of a botch so it may or may not work well. RME interfaces do have multi client drivers so it is possible with those audio interfaces

Thanks mkok
