Yeah I've adjusted the mic input to almost every imaginable option and trouble shot with the guys from contour when it happened on the FIRST camera I bought. It's loud enough but sounds dull and muffled. I'm not picky, I don't expect Dolby surround, just audio that doesn't sound like I'm talking to someone through a Motel wall.
FYI - there are even MORE people with this problem, at least another 3 on their website complaining of the exact same thing.
They stated they will be sending me a THIRD camera that they will test first. I will keep you all updated. In the meantime, purchase wisely....
Bought the first one October 15
Got my replacement THE DAY IT WAS MADE available at the Canadian distributor (literally drove there) last week. that's 2 months later.
and here I am again. awesome.
