So I install a new SB Audigy into a WinXP machine and I test the microphone out. I can't get any sound to pass through. I decide to look in the audio setting in the control panel and the mic is muted. I click to uncheck mute, windows then frowns and says no mic for you. The check won't come off the mute box. I have tried looking online for answers and 90% of them are magically resolved with time being the cure and the last 10% have answers which obviously don't work like "just uncheck the box" or "Make sure the mic is plugged in". Does anybody know what the heck is causing this? Or better yet how to fix this without me blowing away the windows installation.
