There is a way to get rid of sounds, but you need to backup the sounds you are removing. Copy and paste all the sounds that are relivent to the situation, (of course from the program files to your desktop or something) open them using Audacity or something similiar, then turn the decibels right down (maybe -30) save them, and make sure they are the same name as they were in the soundbank or watever folder. Remove the original sounds (if you haven't allready) and place the new sounds in. It works...I tried it with the footstep sounds for metal. They annoy the crap out of me.

Theres the link to Audacity. There are other programes out there, but i find Audacity easier to use.
When they no longer provide a means of entry, then we try harder, until then, you continue to spark anarchy, my fellow anarchists.- CEO, AN.
