As well as all the good advice above, which likely as not will more than cover your problems I would add....

are you sure it's not capturing? The wording you have used implies that as you can't see or hear anything in the capture utility you are merely assuming the capture is not working. Especially as the camera control are all working.

My camera does not display video or sound in Premiere while capturing at all but it does capture fine. I simply have to watch the screen on the camera for my preview. The difference here though is that I am prompted to do this.
