The video plays just fine with both video and audio on the phone, but when you transfer it to a computer the video still works but its audio does not.
I tried emailing the file and directly transferring the file via USB to my PC. I made sure my PC's sound was on and I tried using different video players (VLC/Windows Media Player) and checked the audio channels to see if it would fix the issue, but it didn't. If there's any way to figure out how to fix this please post up, otherwise I will never be able to take and share videos with this phone. 
Edited to start new discussion.

The file format is a .3g2 file. I've run .3g2 files on my computer before from different phones and they work just fine. The .3g2 video files specifically from my Samsung Brightside are the only ones that don't have audio working. I tried it both on my laptop and my desktop and the noise just won't come out.
