If your video file that you imported does not have sound, it will be automatically disabled. If the mp4 you imported was large, it could be an issue with compression. I don't see anything wrong with the code

My video has sound, I compressed it with vlc player (it's about 5mb), when I try to play on my computer - everything is ok. I don't know why is sound disabled, and why don't working, but thanks anyway Brett.
