need help changing sound files for a Workshop Mod

so I've tried changing mp3's for the civ jingles, and that worked flawlessly. But when I try to change any of the other sound effects, (specifically the ones located at Age2HD\resources_common\drs\sounds) it never works. I've tried changing them to .ogg and .wav like they are in the default game, but I can't seem to get them to change. Anyone know a possible solution? or is it just some mess up on my part?
