Mortal Kombat (2011) Endings

In Mortal Kombat (2011), the arcade endings seem to indicate some kind of weird twisted future for Mortal Kombat. Like Liu Kang becoming a tryannical god, or Shang Tsung becoming a hero, Cyber Sub-Zero becomes a combination of Cyber Sub-Zero & Shao Khan.

I've seen at least half these endings but when I unlock some of them, they come with no subtitles or usually I can't hear the ending like the audio is missing. Is it because my account not being gold? Or is it because I beat it under tag team arcade? Has anyone else encounter this problem? & if they have, did they fix it somehow? Please let me know!
