I am looking for audio driver for Intel Cortez D945GCZ. I don't have sound card, it is in-built in the motherboard. I downloaded "AUD_allOS_D20001.0x_PV_IDTGUI_v105_Legacy.exe" from intel driver site; but got msg that hardware is not supported. I used lavalys EVEREST home edition to find the motherboard name. Please help!!!
