I feel Your frustration.
I am also looking to find the last Audio Driver Update: Intel Desktop Board D965 Sigmatel (IDT) 92XX download that contains Intel Audio Studio 2.7 plus the Sonic Focus Encoders (that support the audio studio) for both Windows Vista and Windows XP.
Currently, the Intel Audio Studio has been discontiuned (as Sigmatel is out of business), and no loner supported. The Express Driver disk is currently no longer available, and ALL websites are linked to the broken Intel download link - I can't find it anywhere.
I contacted Intel Support - no luck.
Try Ebay for the Express disk , you would be suprized how many of those are available.
I've tried for a few days now to hunt down the last update that contained the Intel Audio Studio 2.7 goodness - but no luck. ALL links lead to the Intel Download Center which no longer holds the download. There's not even a mirror copy floating around, which is REALLY frustrating.
