When the microphone does not work properly on Windows, you can follow the following steps to check: 1. Check the physical connection and hardware status, confirm that the microphone interface is correct or try to replace the socket and other device tests; 2. Check the microphone permissions and default device settings to ensure that the system allows the application to access the microphone and correctly select the input device; 3. Update or reinstall the audio driver, operate through the device manager or go to the manufacturer's official website to download and install; 4. Run the audio troubleshooting tool, and use the system's own functions to automatically detect and repair problems. The above methods can usually solve most software and setup problems. If they are invalid, they may be hardware damage and need further treatment.

The microphone does not work properly on Windows and may be caused by a driver problem, a system setup error, or a hardware failure. The key to solving this problem is to gradually investigate, start with the simplest inspection, and then go deep into system settings and driver management.

1. Check physical connections and hardware status

First, make sure there is no problem with the microphone itself, especially for external microphone users:

• If it is a USB microphone, try changing to a USB socket or testing it on another computer.
• If it is a 3.5mm microphone, make sure the socket is correct (usually pink) and check if the headphones/microphone is inserted in the wrong hole.
• Built-in microphone users can try to test in other applications, such as using the "Voice Recognition" or "Voice Recorder" app that comes with Windows.

Sometimes, if you just don’t plug it tightly enough or the microphone is damaged, eliminating these basic problems first can save a lot of time.

2. Check microphone permissions and default device settings

Windows will restrict the permissions of applications to access the microphone. If you find that some applications cannot record, the permissions may be that they are not enabled:

• Open Settings → "Privacy" → "Microphone" to make sure "Allow apps to access the microphone" is on.
• Scroll down to see if the specific application is allowed to use the microphone.

In addition, the system's default recording device may be switched by mistake:

• Right-click the taskbar volume icon and select "Sound Settings".
• In the "Input" section, make sure that the microphone device you are currently using is currently selected.
• If you can't see the device, you can click "Test" next to the device name to see if the system can detect sound input.

3. Update or reinstall the audio driver

Driver problems are also a common reason why the microphone is not working. You can try the following:

• Press Win X and select Device Manager.
• Expand Audio Input and Output or Sound, Video and Game Controller.
• Right-click your audio device and select "Update Driver".
• If the update is invalid, you can try "Uninstall the device" and then restart the computer and let the system automatically reinstall the driver.

Some computer manufacturers (such as Dell and HP) provide special audio driver download pages. If you are not sure which driver to use, you can go to the official website to enter the computer model to find it.

4. Run the audio troubleshooter

Windows comes with an audio problem troubleshooting tool that can automatically detect and try to fix some common problems:

• Open "Settings" → "System" → "Sound".
• Scroll down, find the "Troubleshooting" section, and click "Run Audio Troubleshooting" next to "Sound".
• Follow the prompts to complete the detection and repair step by step.

Although this tool cannot solve all problems, it can help you quickly eliminate some system-level setting errors.

Basically these are the methods. When encountering microphone problems, don’t rush to change the device. Check it in order first, and the cause can be found in most cases. If you have tried it all but it doesn't work, it may be because the hardware is broken. You can consider changing the microphone or contacting the after-sales service.
