A small problem with playing this movie (volume)

I have this movie I want to play. It plays fine in Windows Media Player (and in any other media application), though the volume seems to not work. I am pretty sure there is sound but I have my speakers at full level, I have checked the system volume (it is at full peak) and I also made sure any other applications don’t have their volume level low.

Whilst my speakers are at full peak, I can slightly hear speaking voices. Would there be a way to decrease the movie’s volume so I can hear it or I can’t do anything about it? The movie’s sound right now is just static noises like paper shuffling.
