When I added my camera to vMix (by adding my video capture card) I turned off the audio using the lower right audio button. I don't wany my camera capturing any sound, as I am using a desktop microphone plugged into my computer via USB. That worked fine, but for some reason when I cut to different scenes I've created, it turns my camera's audio back on, causing vMix to capture both my desktop microphone and my camera's microphone, creating a hollow echo loopy sound. Why would my camera's audio keep turning back on just because I'm cutting to a different view or a zoomed in image of the same camera, and how to do stop this from happening? Thank you!
