Error Failed To Create Direct Music Performance

[Ink]

Hi I have a problem where whenever I opened up the game a message saying "Error Failed To Create Direct Music Performance" pops up, but the music is fine.
The thing is that while the music is ok the rest of the sound is simply... dead. There are no sfx when something blows up or a weapons fires.
Occasionally i would hear a very fast static-y sfx a few seconds after I click something in the main menu.
So huh?
