Corrupted or Missing Driver - Code 39 : IDT High Definition Audio CODEC

Question

I recently assembled a new computer and tested Windows 7 Ultimate N for a about 10 days and everything worked fine. Later i purchased a license copy of Windows 7 Ultimate (Not N) and made a clean install formatting everything. But after installing my IDT High Definition Audio CODEC stopped working and every application using sound output seized to work. Was able to get basic windows explorer and internet explorer by disabling all windows sounds. Tried disabling all my addon hardwares like GPU's, TV Tuner, Bluetooth and reinstalled IDT drivers couple of times, but still same error in device manager "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)". I even reinstalled Windows 7 but still in vain. I do not have access to any other versions of windows 7, Vista or XP to test at the moment.

My Basic system info as below:

Operating System: Windows 7 Ultimate 32-bit (6.1, Build 7600) (7600.win7_gdr.100226-1909)

System Model: DP45SG

Processor: Intel(R) Core(TM)2 Quad CPU    Q8400  @ 2.66GHz (4 CPUs), ~2.7GHz

DirectX Version: DirectX 11

Video Card name: NVIDIA GeForce 9400 GT

DAC type: Integrated RAMDAC

Dedicated Video Memory: 1007 MB

I dont understand much of technical things but please let me know all possible troubleshooting methods to solve the problem.

Hi Anurag,

Is this the IDT driver version you have installed?

If not, please uninstall the current driver from device manager and select the "delete driver" box. Then install the latest driver from the link above.

Thanks,

Chris
