Intel High definition Audio HDMI driver update

Ok, I have been having issues trying to get my HDMI audio to work as I have posted on another post/thread.  Long story short I upgraded my inspiron 1525 from vista home basic 32 bit to windows 7 premium 32 bit and lost my HDMI audio.  I did receive assistance from another Dell forum person that provided me with some driver info to try and correct.  I am trying to locate the following driver update

"Intel High Definition Audio HDMI"

Driver Date: 7/10/2009 

Driver Version: 6.10.1.2077

It seems that this particular driver is no longer offered on the intel site is there another way to locate it?  I did the update driver and it tells me that the verison i currently have which is the 6/6/2007 version 6.10.0.2035 is up to date.

Locating driver updates has truly been a challenge for me any help provided is greatly appreciated.
