Windows 7: Microphone not working on Windows 7 Home Premium 64 Bit.

Recently upgraded from Windows XP to Windows 7 HP 64 Bit. Microphone was working fine before I upgraded the OS. Also I've noticed my previously working IDT Audio Control Panel is now missing, tried to re-install but to no avail. Currently in the Device Manager, the Audio Device is High Definition Audio Device. Also, under Sound, Recording, Microphone is not plugged in. I have already checked 'Show disconnected/disabled devices'. My speakers are working fine, just the microphone. It is plugged into the 3.5mm pink jack, I do not have any front microphone jacks. Have also tried to update the drivers but no changes.



I suppose installing an Audio Device Manager and identifying the devices according to the ports will work, but none of these audio managers like RealTek or IDT work for me, which I am not sure why.

Motherboard: Intel D946GZIS


Any help will be greatly appreciated.

Thanks,
Jonathan

The IDT (previously called SigmaTel) drivers are needed. The Windows installed HD Audio Codec are a basic function driver and will provide sound, but depending on the hardware sound chip may not provide all functions.

Here is the IDT driver from the Intel downloads. Install this and see if fixes the problems.

Hi, fireberd. Thanks for the reply, however I received an error 'The hardware detected is not supported by this IDT package. The install will be aborted.' I believe I do not have any soundcards other than the built-in one.

The Intel list of applicable motherboards for this download lists your motherboard?

Download the Intel motherboard chipset driver and install that, then try the sound driver again. If the correct chipset drivers were not installed the devices on the motherboard will not be detected or correctly detected.

Yes, it lists down my motherboard D946GZIS. Do I need to run the Audio Driver setup in compatibility mode or anything?

No, it should work as is. Vista drivers are valid for Win 7. Try the chipset drivers that I referenced first as that may make a difference.

Hello, I have tried updating my chipset drivers and then the IDT drivers. Now everything works, thank you!
