How to turn down audio?

[Harbinger]

I want to watch a movie while playing the game, but the game is pretty loud. However, I couldn't seem to find any audio options. So, is there a way to turn down the volume of the game?

unfortunately there are no in-game sound options - but if you have Windows 7 - click on the image of the aspeaker in the bottom right hand side of your screen. Then click 'Mixer' - you can control the volume of individual programmes there.

If you have a keyboard which has volume controls, use them.
