Underworld Twisted Fate Has no Dance Audio

Whereas his other skins (or at least Default, the only other one I own), plays audio when he dances, it does not do so in Underworld. I'm not sure if other audio is also missing, such as the audio for when he ults, which I'm not certain that I've heard.

Here is a video I've created, showcasing how the audio is supposed to work, followed by how Underworld works, by request.
