I'm lost. My husband is having a meeting on Saturday that he would like my help livestreaming to an audience at a distance. There will be a speaker with a microphone, and a stage. I need to find out how I can use my Sony a5100 to livestream through my computer, but also how to get the audio input from the microphone on stage, not just the microphone on the camera. I have no idea where to start. I know this sounds complicated but this will be a regular occurrence and I'm trying to get things up and running for Saturday. Any advice as to where to start?
