Hello. Using Windows 10/ laptop audio out Into an ATEM Mini switcher mic input. Using several camcorders into same ATEM (external mics sound fine through camcorder/ATEM). Running OBS out to Facebook Live. Audio out from laptop sounds *terrible* trying to fade in/out music loaded on the laptop through the ATEM. Cannot figure out why. Sounds distorted terribly. Audio hum outweighs sound quality. Hiss/channel overloads. Does anyone have a clue???
