Just bought my first GoPro Hero 3 Silver edition and have recorded 2 videos both about 20 seconds long. I was holding the camera in my hand and not in the waterproof case. When I viewed the videos on my Windows laptop, the audio seems EXTREMELY LOW. Even when the camera was right in front of my face. I have done the required update already so I'm not sure if I just need to adjust a certain setting to fix this...or am I out of luck?
