Adding Sounds to WoV2?

[Stretch32 0]

I was looking around the net tonight and found a pretty neat .wav file for my cannon sounds but after creating a "Sounds" folder and renaming the file "Cannon" I don't get any cannon sound. WoV2 obviously "sees" the file because its overiding the default cannon sound but I hear nothing at all when I fire cannons (F-8 Crusader). Any thoughts? Do I have to modify or edit a basic .wav in some way to make it work? I've never actually tried to install my own sounds only D/L a few that were available here. Thanks for the help.
