Screenshare and audio

I have been using for a while on a surface pro with Windows 10, and when working with children, I have been able to share my screen along with any audio that came with any of the videos that I used. I did notice that for some reason I could only use Google Chrome in order to share the audio. I have recently now switched to a larger HP laptop that has Windows 10, and am using Google Chrome, however, my kids are not able to hear any audio. I have tried to use the guidance I saw somewhere else, regarding downloading a virtual cable and using stereo mix, however, that is not working either. Does anyone know another workaround that I can use to get the audio working while sharing my screen? Thanks in advance.
