Larsin just because you have never had a problem does not mean that problem does not exist.. The forums are full of the onboard sound problems for COD4 . Just search for iw3mp.exe error in these forums or on the net . The problem is there and still very much alive. Mule asked for advice and if he plays COD4 my advice is to get a sound card or use an usb setup. Or take the chance that the problem is gone. As I recall my solution to that problem was to just use a usb mic. So he can use onboard sound and a usb mic. But again thats just one of the many solutions to the sound problem. But again sound cards are much cheaper then a good usb mic. So thats my advice and thats all that is.
