There is a free program called Open Broadcaster that claims it can stream surround sound audio. It won't work on YouTube Live or regular Facebook Live, but it will on Twitch, Mixer and Facebook Live 360 with spacial audio. I not clever enough to figure out how to use this but maybe some of you out there might be interested.
