Sound/Audio Controller Driver Problem

I'm Only Kid to Know...
I Just want to say, When i installed Realtek 9'7 for VIA (R), it never
start working, so i Unistall it, My Current Device is VIA 9'7 ENHANCED AUDIO CONTROLLER i think theres no version.. I'm Looking for the program that i
can use.. I'm Using Windows XP Service Pack 3 Beta 2 w/ Vista look but
it is not SP3 it is SP2.... in SP1 my Hardware Update Wizard detects
my Audio controller but in SP2, It cant search for it..

for moderator or user will answer, thank you very much!
