Probably not the right place where to ask, but possibly the best one I could find to get an answer. Sorry if it is not super relevant to this forum.

Is it a problem on my install, or is it normal that custom race have audio disabled in the intro sand end cinematics?

Is it possible to mod the game so that when playing a custom race, the intro video and end video after game is won play using the audio of the race selected for the custom race?
