Hey Dean, maybe it is an amp setting on your camera microphone? A little engine noise or other sounds would enhance the video, so I don’t think you should turn off the camera mic.
The “Oh see you later” video up above sounds fine on my computer, so I don’t think the issue is a volume setting on my playback.
Just so you know, I’m no expert on action cameras. I recently bought a cheap GoPro knockoff but I haven’t tried it yet.
