Help! WinXp Sound Problem! (last post is an error)

[Guest]

I came back from work today and had to ! in the Device manager tab... under theses 2
- Microsoft Kernel System Audio Device
- Microsoft WINMM WDM Audio Compatibility Driver

Looked on Windows update to see that the last update was creating some corruption in the compatibility, so i downloaded a patch for XP fixing this issue... and tried to uninstall theses 2 problems so that windows could reinstall them... And now i'm trying to install both and I get an error saying that the driver is not intended for this platform, i reinstall my SB Live... and it's getting nowhere... Help me please!
