Nikon d3200 Speaker Problems?

I have had my nikon d3200 for a couple months now and I love it. One reasons I bought it is because I love making videos. But recently when I have tried to playback my videos on the camera, no sound has been coming out. I put the volume to the max and still no sound. At first I thought I was filming with my microphone off, but when I uploaded the videos to the computer, the sound was just fine. Can anyone help? And does anyone else have this problem?

Two things at play here.

One you can't do "filming" with a digital camera so please learn your terms… You can shoot video.

Two you should not be playing anything from the camera. First the camera is not a display device and was never intended for playback, second that is a very easy way to destroy your memory card… Lots of bad stories out there.

Always upload first, then view.

Lisa, for the life of me I can't understand the infatuation with video with a "still" camera. Why don't video interested people just buy a video camera or a camcorder?

Same Problem. My Dslr speaker is not working. Can any one tell me how to fix it?
