Turn on the computer and make sure it works, if not power it down and try the other 8 pin sound slot.
If neither of those work, you might need to rma your board with asrock.
Was the sound working when you purchased this or no ?
If it didn't work upon receiving it and even having the correct drivers its a problem with the mobo.
