I have a X-Fi PCI soundcard which has just disappeared altogether as far as Windows is concerned, it was working fine the other day then (as far as I can remember) I was on skype and having issues with getting the mic working, I tried something in the audio options which fixed my mic but now the only sound hardware showing up is the onboard realtec, which is not what I want to use. I know the X-Fi was working after I did whatever I did in Skype because the mic is plugged in to my front panel connector which is plugged into the header on the X-Fi but beyond that I'm stumped. I've tried reseating the card, it's definitely in right. The only other thing I've done lately out of the ordinary is capture some video through my firewire card for the first time which right enough was the first time I noticed the problem... Halp! It's plugged into an MSI C45 770.
