The loudness is due to the fact that when I started modding sound it was around the time of the .09,.92 sound mods which were loud , as for the distortion , well there is none on mine , nor my bro's or my mates systems , a fix would be to get yourself an audio editing system , there are loads of eazy to use inexpensive ones avi on the interweb.

Finally, I did it, I found the solution. No need for lowering sounds. I went to Hardware setup and disabled extensions. The sound is now just like in your video. Except for the machine guns. They don't sound loud enough now but I can live with that and I'm sure that will be solved when new sounds come out.
By the way, you're sounds rock.
