So I recently started streaming on YouTube and after a couple of episodes with crappy audio I decided that I should probably use a more professional program (I was using a demo version of Wirecast). After downloading OBS I ran a test to make sure everything was set up properly before I streamed by just wandering around punching and placing blocks in Minecraft and talking into my Laptop's mic for about a minute. When I went to view the video however there was no audio. So twice I changed my settings and tried again meeting with the same result. Could someone help me please, this has left me quite baffled.
