So my windows xp’s sound wasn’t working, and I thought that the sound device on the motherboard wasn’t working, so I installed the X-Fi Xtreme sound card. Still no sound, so I went to the website and installed the files via usb (this pc has no internet) and when I try to open the control panel for it, it says that the device isn’t detected. It’s plugged in correctly (there’s no PCI-E port so it just goes into the motherboard) and I’ve cleaned the contacts with an alcohol swab. Still not working and I have no idea what to do
