The recent update to discord on 5.14.2018 https://blog.discordapp.com/change-l...8-13ddf4d27ca8 had an interesting little gem in it. "Screenshare now includes audio!" To share screens to a group (up to 9 other people), which now includes your system audio, just follow these guides!

This is the perfect way to share your system audio, from say Syrinscape, during a gaming session. You can even select just one program to share, so you don't have to share your entire desktop and give away your dm secrets. It allows multiple people to share screens, so I'd suspect you could even have someone else handle the audio if you want (I haven't tested this part yet).
