When I watch a video on my Kodak easyshare c182 there's no sound what do i do??

First, try pushing the UP arrow on your curser to see volume bar increase on video display. There's really not much in the way of speakers on the camera so you have to listen CLOSELY in a quiet room. The louder the sound during recording, the louder during playback, and vice versa. When transferred to a computer, you will have more control over loudness, especially since you will have ACTUAL SPEAKERS amplifying the sound. Good luck!
