(Go Live) The ability to share audio from another program with the main one on screen

This would be pretty handy in cases such as OBS, which doesn't broadcast audio but rather displays graphics and video, through Discord Go Live.

The reason I decided to write this post was because I was trying to share my screen through OBS and was expecting to see them hear my audio from my projection but OBS doesn't distribute the audio on the program itself. I was hoping to put graphics ontop of the video being displayed whilst also allowing them to hear my audio.

I was thinking of just having my Mic the desktop audio but that'd end up causing them to hear themselves ontop of the audio I was trying to broadcast.
