Windows XP Professional
Service Pack 3
1 Gb ram
Pentium 4 2.66 cpu
Intel Springdale chipset
video Radeon 7500

I want to disable the built in sound on the motherboard and use a Soundblaster card. When I go to System=hardware=device manager under Sound video and game controllers I get
Audio Codecs
Creative SB Audigy 2 (WDM)
Legacy Audio Drivers
Legacy video capture devices
M audio MIDISPORT 2x2 anniversary Edition
media control devices
realtec AC'97 audio
video codecs

Which ones do I eliminate and how do I do it?

Thanks
