I fixed it ! Okay here is what happened, all I did was change the audio in the settings for the sound effects to be at 80% and the others at 90% but for some reason that is what messed it up. Once I changed everything back to 100%, the audio was working again in the cut-scenes. I'm glad that I was able to find this out on my own before trying to return the game and go through all that hassle.
So everyone who has the Wii U version, DON"T mess with the audio setting just in case. I'm going to call Activision tomorrow about this issue and maybe they can do a system update to fix it but for now, leave everything at 100% volume in the settings.
