OK, you need to download this http://downloadcente...oadType=Drivers which is the Video driver for HD 2500, 3000 and 4000. However, inside there is a folder called "ibxHDMI" which contains an INF file with these IDs %IntcDAudDeviceDesc% = IntcDAudModel, HDAUDIO\FUNC_01&VEN_8086&DEV_2805&SUBSYS_80860101, HDAUDIO\FUNC_01&VEN_8086&DEV_2805 %IntcDAudDeviceDesc% = IntcDAudModel, HDAUDIO\FUNC_01&VEN_8086&DEV_2806&SUBSYS_80860101, HDAUDIO\FUNC_01&VEN_8086&DEV_2806 which are the ones you need. The package is easy to extract with 7-Zip, WinRAR or whatever you please. Cheers and please, report back. EDIT: the answer was the other posts in this topic: nowadays they tend to put a lot of drivers in one package (video, audio, chipset, SATA) and call it a suite; ATI does it, so why not Intel?
