Hello! I have a Dell Optiplex GX520 and installed Windows XP (non-oem) on it. However, the sound doesn't seem to work. Not even the drivers provided by dell seem to work properly. I was also thinking about installing a newer/different operating system, like linux mint or windows 8.1, in a different partition. I know the sound drivers don't work in windows 7 or up (like it worked at all) so i was wondering, what sound card will fit in a Dell Optiplex GX520, be compatible with windows, and is cheap?
