audigy original cd drivers for 2k/xp
these are the bare sound drivers
you can try running CTZAPXX.exe. I havent tried it but it may work. what i did was go into device manager and rightlicked on thte yellow unknown driver and hit update driver,then click dont search i will choose, show all devices, have disk, browse to the extracted folder and went to the 2k dir then repeat for the other yellow unknown in device manager
