Also seem to recall that the settings for that audio clip, would have to be made to match the others in use, that it would be replacing... can't recall where those instructions were posted... but, am sure propbeanie would know.
But.. KaleunMarco is correct... that audio file, would need to be nested properly... into a jsgme compatible format... to make rolling back to stock game settings relatively... simple, should you need to deactivate mods...
