I just installed SP3 XP and installed Boot camp drivers off the dvd, and then installed boot camp 2.1 drivers from apple for SP3 Compatibility. BUT. Sound doesn't work. Found an article about others having the same issue here http://www.techarp.com/showarticle.aspx?artno=490 Downloaded those drivers. BUT. When I go to Computer Management > Device Manager I'll go to the properties for the sound card as it DOES say there is no driver installed, if I click "Reinstall Driver" it WILL NOT do anything. If I try to "update driver" or ANY other way to install the driver for this sound card, it will not do anything or take me to the "locate this driver" wizard... IF i do try to "update driver" or "reinstall" on any other hardware in Device manager, it brings me to the driver wizard without a problem. The sound card works GREAT when running in OS/X and when booting the SAME installation with Parallels. I even tried the "Add hardware" wizard in control panel, it says the driver isn't installed for it, but the wizard closes even before allowing me to manually locate it and install it. I just don't understand! I've tried disabling and re-enabling. When I try to UNINSTALL the sound card, it fails as it is "used to boot the system" I don't get it.
