I have Microsoft windows 7 with media player 12 and while videos are downloaded from phone the video appears but without sound. Have all updates to date which I know of. I am running windows media player 12.0.7600.16415. Is there anyone here who knows about this? Please provide me some information or some help regarding my issue. Because, I always makes video of image or any other media files in 3gp and always wants to see it in my cell phone with sound. So please give me some hint.
