There is a lot that is sus-picious in this thread. I'm not sure how to give guidance. The interface doesn't work on this or other computers. The interface can send sound to speakers when it is off (high pitched beep). The OP sees levels bouncing on the inputs when the device is connected. The device is 2 weeks old.
To troubleshoot, he reinstalled Windows and saw no improvement (in 1/2 an hour... takes me 1/2 an hour to install Sonar haha and that would be record time!).
So, I'm puzzled and think he would do best to get tech support from the manufacturer or re-seller on the phone to ensure the device isn't working. I have a feeling if he takes the device in to Guitar Center or wherever he bought it from that he might be able to get quicker help.
