I am running on XP Pro but i am having difficulty with the propor instalation of the sound card. (Sound Blaster: Audigy) Model # sb0090. When i run the setup prosses, with the given cd, it will load completely and say it is finished. But when rebooted, no sound is working, and if any does it is choppy and un-audible. I am wondering if this is a card probleam or a driver probleam, or any other probleam i am not aware of. I have discovered that there is not device conflicks, device is active, and have updated windows drivers multiple times! Thank you for your time!
