It's a Win 2000 driver for Aztech sound Card PCI 288 3QDQ II but it works when I installed Win XP. Install XP, when you select Proprities of sound Card, clic Reinstall the driver, in explorer select "WDMA_TRD.INF" and install it. Win XP will tell that the INF doesn't have a numerique signature, but select Continue and it's all. You don't have to reboot.
I've Packard Bell Computer Platinum 7536 and I have no problem with my card sound still I installed the driver WDMA_TRD.INF. The link where I found this driver is www.hoontech.com/korean/download/driver/Nx_dx/win2000/nx/nx2knew.zip
PS excuse my english...not perfect.
