Hello,

I have a Dell Studio XPS 8000. Recently my graphic card fan started to wear out leading me to getting a new one since my warranty had expired. Everything is fine on the computer except now my front mic and headphone jack are no longer working. I am using Windows 7 (64 bit). The front microphone port is detected under recording devices but displays as "not plugged in". the front headphone port is not detected at all. 

I have no idea if this has anything to do with it or not, but my new video card has an HDMI output which also carries audio. The audio for the HDMI cable is detected. 

Any help is appreciated,

Thanks
