I have a C920 webcam that I'm using the microphone from that to stream. It almost sounds like OBS is detecting two instances of the microphone and it's causing an echo. If I disable the microphone in OBS (like so: http://imgur.com/tJZiKyd), the microphone still picks up signal, it's just extremely choppy. "Listen to this device" is disabled in the microphone's settings. I don't get what could be causing this to occur... I can't win. This one actually has me stumped.
