This somehow all worked. Audio comes from my hard drive, goes through my S5 sound card, out to my Soundcraft 12 MTK, back to MMV, then A/V goes to OBS, then through FB live right to your face. What an age to live in. Here is the FB live test:

I'll be going live at 8:00pm EST for a 3-4 hour set of open format goodness. Friend me on FB if you wanna dig it: Ivan Jones
