Streaming audio from a game to voice chat, mixed with audio from microphone

[Patrick May <dusthillresident@xxxxxxxxx>]

Hello,

I want to stream audio from a game to discord, while also sharing my mic 
at the same time.

This is a very common thing that people do all the time on other 
operating systems. For some reason this seems to be almost impossible to 
do with Pulseaudio.

Why is it so difficult?
