We are using OBS to stream our Church service. I noticed Sunday that we dropped our audio several times. We are using the Blackmagic ATEM mini with an audio cable from the board to it, a camera running HDMI to it, and another computer for graphics running to it. I checked the switcher software and we never lost audio. I was able to get the audio back by going to the audio properties and unclicking and re-clicking the capture audio. Here is a log file.
