As stated in the title, there are some missing audio assets when trying to play BO1. When I start the game, The interrogator guy's audio works, but when Alex Mason starts talking at the beginning, There is no dialog, but the rest of the ambient audio works. This is just 1 example. There is missing dialogue throughout the game. Not sure if its an issue with DODI's repack itself.
Edit: Can confirm that it's not only DODI's repack.
Edit 2: Fixed by installing wmp11
