Why is there no sound, and the screen is black & white?

Just prior to the live event, or during a break, it is common for us to start filming in the studio from one of our "spy-cam" GoPro cameras. 

While this is a live preview, there will not be sound during this time, as our production team is still preparing for the broadcast. 

Once the course starts, the stream will transition to a view with color and the sound will available.
