Hi,
Welcome to the Community. If you have just reinstalled windows then first check the below link on how to install drivers in the correct order, or some devices may not work properly.
Try reinstalling the Audio driver from the support site.
Click on start, control panel, sound Recording tab. Is Microphone/Line In IDT High Definition Audio Codec selected as the default device?
Let us know how it goes.
Thank you.
i had downloaded and installed sound driver from this site the problem is my internal microphone is not working. what should i do?
Downloading the driver probably did not have anything to do with the mic not working, but if you think it did then you can undo it by using Windows System Restore. Find a restore point dated from before you installeed the new driver and choose it.
In XP, go to Start>All Programs>Accessories>System Tools>System Restore
and tick 'Restore my computer to an earlier time'. Choose a date before the problem first occurred.
In Vista and 7, type "System Restore" into the Start menu search box, and then, in the list of results, click System Restore.
If you do not have an appropriate restore point you can still undo it by going into the properties of the audio driver and select "rollback driver" which will re-install your old driver.
If you need more help then please reply back with the full model name of your laptop and the name of your operating system.
This didn't work for me.
