Sound?

Ive been looking for a video or audio diary for a long time and couldnt buy this fast enough but the sound on replay is barely audible. Am I doing something wrong? And no, Im not covering the mic. I also saw a review that said audio/ video is for I only 60 sec increments. Hope this isnt true.
