My DUH! question of the week: I just changed the OS on this computer to XP Pro; a full install, not an upgrade. My soundcard is a Soundblaster Live MP3 + 5.1. The CDs that came with it (Installation CD and Applications CD) come up as non-compatible with XP. Everything seems to be working fine without installing any Soundblaster software. Do I really need to download and install any drivers (LiveDrvUni-Pack) or applications, or should I leave well enough alone?
