Can't get in-game audio to work

I have just bought the Tritton 720+ but I have been trying to get the audio in Call of Duty for example to work. It only plays out of the TV.

Depending on what device it is I would say that on PC you would simply have to change the default device in playback devices to the headphones you are using.
