Last night I was streaming a live sporting event. I have 2 commentators on headsets and a crowd mic through a Focusrite Scarlet box, XLR. I also have an audio source from a camera through SDI into a decklink capture card feeding into Vmix. Out of nowhere I lost all audio in my headsets as well as my commentators headsets. Luckily, the audio was still live on the Master channel so the people at home didn't know anything was wrong. No cables were unplugged, we never lost power. It seems like it was just a software issue, perhaps with one of the other audio buses. Play x Play is on A bus, Color is on B bus and Director is on C bus. I lost talk back to my commentators and vice versa. Today I turned on the same preset just to test and it is all working just fine. I have the most up to date version of Vmix. Any ideas what would have caused this? I am on a windows PC. Thanks!
