The microphone is not available on Windows 11, which is a problem that many people will encounter. Sometimes, the system cannot recognize the device even though the device is plugged in, or the sound is intermittent and even completely unresponsive when recording. This problem is usually not that the hardware is broken, but that there is something wrong with the setup, driver or permissions.

Check if the microphone is disabled

In many cases, the microphone is actually muted by the system or application. You can check this way:

• Open the volume icon in the lower right corner of the taskbar and click "Open Sound Settings"
• In the "Input" section, see if the current microphone is displayed as "No Active" or "Not Insert"
• Confirm whether the volume slider below has been pulled to the bottom, or there is a small fork next to it

If you see "not inserted" but the microphone is clearly plugged in, it may be that the system is not correctly identified. You can try to unplug it and plug it in again, or try changing to a USB port.

Check the default audio input device

Windows 11 supports multiple audio input devices, such as external microphones, headphone microphones, built-in microphones, etc. If you do not select the right one, the sound may not be recorded by default.

The operation method is as follows:

• Right-click the volume icon in the taskbar → “Sound Settings”
• Scroll down to find "Advanced Audio Options" → "Manage Audio Devices"
• Switch to the Recording tab
• Check which device has a green checkmark (indicates that it is being used). If it is not the one you want, right-click and select "Set as default device"

Sometimes even if the default is set, it may be restored to other devices after restarting, so it is recommended to check it regularly.

Update or reinstall the audio driver

Drive problems are a common cause of microphone not working. This situation is more likely to occur after just upgrading the system or replacing the hardware.

You can do this:

• 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" or "Uninstall Device"
• After uninstalling, restart the computer, the system will automatically reinstall the driver

If manual updates are useless, you can also download the latest driver to install on the motherboard or sound card official website. Some branded phones (such as Lenovo and Dell) also have special driver management software, which can be used to update in one click.

Check privacy settings and application permissions

Windows 11 For privacy protection, microphone permissions for certain applications may be turned off by default. If you cannot record sounds in a certain software, such as WeChat, Zoom or browser meeting functions, you have to check whether the permissions are enabled.

The steps are as follows:

• Open Settings → Privacy and Security → Microphone
• Make sure "Allow access to microphone" is on
• Swipe down to find the app you want to use, and make sure the switch to the right is "Allow"

Sometimes, even if the total permission is enabled, some applications still cannot be used. At this time, you can turn it off and then open it again, or try to restart the application.

Basically, these common investigation directions. Most of the time, checking it in sequence can solve the problem, and there is no need for too complicated operations. However, if you have tried all the methods but still can't work, then you have to consider whether the hardware is damaged.
