Can't get any sound to play on Pro Tools 8.0.4

[brandoncunning]

I have recently installed Pro Tools 8.0.4 on a computer that I just bought. When I go to play audio the meters are moving but there is no sound. I have the inputs plugged into the Mbox in the correct spots. I even looked at the device manager and I have Digidesign Mbox 2 Audio and Digidesign Mbox 2 Midi selected under sound, video and game controllers. I have disabled Realtek High Definition Audio which is the onboard sound card. When I turn the computer on and I have the Mbox attached with the speakers the speakers will make a popping sound when turning on. I am not getting any windows sounds either. Should this be coming through? If somebody could help me figure this out I would appreciate it. I am going to post my system information if that helps. I have tried looking through posts to find an answer.
