I downgraded my laptop to WinXP Pro and I am having issues getting my sound up. I installed drivers for the audio, and when I look in the device drivers, there shows no errors for sound at all. When I look in the sound options, it shows no audio device installed. How can I go about and delete the drivers I installed so I can try something else? I don't know what was installed and where. Can I say it is safe to assume if I clear all the audio codecs that it should clear what I installed?
