Hi.
MiA_HitSound.ini:
[MiA_HitSound.HitSoundGR]
HitSoundName=MenuSounds.Select3
bListAsMut=True
Edit the HitSoundName property. For example, if you have a sound called "MySound" which is in package "MySoundPackage.uax", you would have to make the ini look like this:
[MiA_HitSound.HitSoundGR]
HitSoundName=MySoundPackage.MySound
bListAsMut=True
Since this sound would be custom one, clients would have to download MySoundPackage.uax. To do that, you would have to edit your ut2004.ini:
find [Engine.GameEngine], there's a list of serverpackages, eg ServerPackages=xVoting. Add "ServerPackages=MySoundPackage.uax" to the end.
MySoundPackage.uax has to exist in your server's "Sounds" folder of course.
