I went to C-Media website, and it directed me to Driver Doctor to make sure that I would choose the correct driver. After spending a long time downloading the program, it required a fee greater than the price of the hardware for which I wanted the driver. So I refused. I think that the creators of the program had decided that I should be punished!! For when I returned to use my computer, it was if some very nasty virus had gotten in. Many things didn't work. To make matters worse, even System Restore didn't work properly. It was the worse thing that has happened to that computer since I bought it about 4 years ago. Be very wary!
