I recently had to reinstall windows 98, when I did my sound card wouldn't work. I have downloaded the same soundcard driver from various different locations but for some reason it still isn't working. I have done every obvious thing possible. I now need someone knowledgeable to help me out. I keep being told that there is no PCI audio device driver...I don't know why. Anyhow, my soundcard is.. CMI8738/C3DX from C-Media. ANY help at all would be awesome, thanks!
