the computer detect the microphone plugged in, but it's not working with any App. or Desktop soft wears , It's worked on my Windows 7 Laptop, I'm using Realtek HD Drive.

rom your issue description, I understand that your headset microphone does not work with any Apps or desktop software on your computer, although it is detected by Windows 8 when plugged in. I would like to ask you a few questions regarding this issue.

1. Did you upgrade to Windows 8 on this computer or is it a brand-new computer that came with Windows 8 preinstalled?
2. What is the make and model of your computer?
3. Did the microphone work properly on this Windows 8 computer previously? If yes, then what is the recent change that you have made on the computer prior to this issue?
4. If you are using a desktop computer, on which panel (front or back) are you facing this issue?

This might be due to some incorrect audio settings or it might be due to the out-dated audio HD drivers. Let’s try the following methods and check if that resolves the issue.

Method 1: Make sure that the Microphone is not disabled and is set as default.

Make sure that the microphone that you are using is not disabled and is set as default in the computer. Follow these steps to check this:

c) Select “Microphone” and click on “Properties” and make sure that the microphone is enabled.
d) You may also check if the microphone that you are using is set as default.

Now, check the issue. If it is already enabled, then try the next method and check the issue.
