Windows 10 may not hear the sound of your microphone for a variety of reasons. All the usual troubleshooting steps for the PC microphone are still important, but Windows 10 includes a new system-wide option that completely disables microphone input in all applications.
Checking Windows 1
0 microphone options
The Windows 10 Settings app offers several options Disable your microphone system-wide in all applications. If your webcam is disabled in settings, even desktop applications can not receive a microphone input.
This is a bit confusing. In general, app permissions in Settings> Privacy affect only new applications from the store, also known as Universal Windows Platform or UWP applications. However, the microphone and webcam options also affect desktop applications.
If your microphone does not work, go to Settings> Privacy> Microphone.
Check at the top of the window if "Microphone access for this device" is displayed. "If Windows Microphone Access is disabled, click the" Change "button and set the option to" On ". When access is disabled, Windows and all applications on your system can not access the audio through your microphone.
Under it, make sure "Allow apps to access your microphone" is set to "On". When microphone access is disabled, all applications on your system can not hear sound from your microphone. However, the Windows operating system itself still has access.
Under "Choose which apps can access your microphone", make sure the app that wants to access your microphone is not listed and set to "Off" Case, set it to On.
Only apps in the new style from the store are shown here. Traditional desktop apps from outside the store will never show up in this list and will always have access to your microphone as long as the "Allow apps to access your microphone" setting is turned on.
Make sure your microphone isn is not otherwise disabled
You can also disable your microphone in other ways. If you have a laptop with a built-in microphone, you can disable this microphone in some of the laptop manufacturers in the BIOS or UEFI settings of your PC. This option is not available on all laptops, but is likely to be near an option that lets you disable your webcam, if any.
If you previously disabled the built-in microphone through your computer's BIOS, you must do so to return to your BIOS settings and enable the microphone again.
You can also disable the built-in microphone through your computer's Device Manager. If you have already done so, you will need to return to Device Manager and reactivate it.
Installing or updating audio drivers
Windows 10 attempts to automatically install and update device drivers. Usually this works fine, but sometimes not.
If you have problems with the sound, you should go to the PC manufacturer's website and install the latest sound drivers available for your laptop or desktop PC. If you have assembled the PC yourself, download the audio drivers from the motherboard manufacturer's website. Upgrading the drivers may solve the problem.
If you have problems with a USB microphone, you might also want to download the latest drivers for the USB controller from the PC manufacturer's website.
Check physical connections
] If your microphone does not work, make sure it's firmly connected to your PC. If the connection is a bit loose, it may seem that it is properly plugged in, but may not work. Unplug the cable (whether it is a USB microphone or just a conventional audio jack) and reconnect it to make sure the connection is secure.
Make sure the right audio jack is connected to your PC. Look for one labeled "Microphone" or at least "Audio In". The output audio jacks are often green, while the microphone input jacks are often pink. Sometimes they are just the same dull color.
Some microphones may have mute controls. For example, we've seen PC audio headsets with microphone mutes on the cables. The microphone does not work when the mute switch is activated.
Using the Sound Control Panel
When testing your microphone, we recommend using the Recording tab in the Sound Control Panel in Windows. To open it, right-click the sound icon in your notification area and choose Sounds.
Click the Recording tab and you will see all the audio recording devices on your PC. Speak loud and you will see the meter on the right when the microphone is sending an audio input.
Take a look at this window as you play with the microphone and test different audio jacks. This will allow you to quickly see if the microphone is sending audio input.
Set Your Standard Microphone
Your PC may have several different microphone inputs. For example, if you have a laptop with a built-in microphone and you connect another microphone, your PC now has at least two separate microphones.
To select the standard microphone used in applications, go to Sound> Recording Right-click on your preferred microphone and select Set as Default. You can also select Set as Default Communication Device.
Allows you to specify different standard microphone inputs for different types of applications. Just schedule an input device and set it as the default and standard communication device.
If your microphone displays audio input here, you will not be able to open it in one In a particular application, you may need to open the settings window of that application and select the appropriate microphone input device. Desktop applications do not always use the standard microphone that you selected in the Windows Sound Settings.
For example, in Microsoft's Skype, go to Menu> Settings> Audio & Video and select your preferred microphone device from the Microphone menu. 
Running Windows Troubleshooter
Windows 10 has built-in troubleshooting that attempts to automatically detect and troubleshoot audio recording problems. To access it, go to Settings> Update & Security> Troubleshooting. Select the Audio Capture troubleshooter, click Run Troubleshooting, and follow the instructions on the screen.
If it still does not work
If your microphone still does not work There may be a hardware issue. Connect the external microphone to another PC and see if it works. If this is not the case, the microphone hardware may be defective.
If the microphone is working on another PC but not on your current PC, there may be a problem with the audio jack on your PC. Connect the microphone to a separate microphone input jack, provided you are using a PC with audio jacks on the front and back.
