I googled for the net and found out that many folks did ran into the same problem after upgrading to 64-bit Vista. 2 SigmaTel IDT STAC 92XX C-Major High Definition Audio Driver. Sound cards such as the SigmaTel High Definition Audio Codec must have certain compulsory features such as multiple sound chips which enable it to give a much faster data rate as well as have several concurrent functionalities, for example, digital sound production vis-vis synthesized sounds such as in real-time music generation.Download sound card.
The latest working (official) version I've been able to find is. I checked Sony’s support site for my PC model but they don’t seem to have a 64-bit version of the SigmaTel HD Audio Driver.

It all started when I discovered (after all those years) that recording the sound from your computer doesn't require a cable to connect the output with the mic.
