Would assume that you press the button for volume adjustment and then press the up/down buttons to adjust it. If you can't access that function, make sure the audio cables are properly connected and that any drivers/software it came with are up to date. Might also want to check the system volume on your computer itself to make sure it wasn't turned to mute.
