Disabling own footsteps.

I searched on the internet for a way to disable my own footsteps in UT2004 in order to improve my 1v1 performance and i found this:

[UnrealGame.UnrealPawn]

bPlayOwnFootSteps=True

Setting this option to False will turn off the sound of your own footsteps.

In user.ini, under [UnrealGame.UnrealPawn] I had this 2 lines:
bPlayerShadows=True
bBlobShadow=False
and I added the one that I mentioned above, I saved the file and entered UT, but I could still hear my footsteps. Then I started looking through user.ini again and I found the "bPlayOwnFootSteps=True" line under [XGame.xPawn] and I set it to false there too, but I could still hear my footsteps.

Anyone knows what i should do?

Thanks.

and is there any way i could disable the sound that my character does when i dodge or jump?

thanks
