Sound Card drivers


In Runtime
This is the soundcard that I purchased:

I only bought it to see if the problem I was having with my mic was due to the input jack on my computer. The only problem is it never came with a driver CD and now I don't know what to do. I search up the chipset in google and download the driver and when I go to set up the driver and install it, it tells me I don't have that chipset. Anyone have any ideas>?
