Windows 10 microphone not working. what to do?

One of the common problems in Windows 10 is microphone issues, especially since the recent Windows update. The microphone may NOT work at all or in some specific programs, for example, in Skype, or in the entire system. In this instruction, step by step on what to do if the microphone stopped working in Windows 10 on a computer or laptop, both after updating, and after reinstalling the OS, or without any action at all from the user. There is also a video at the end of the article that demonstrates all the steps.

Before proceeding, be sure to check the microphone connection (so that it is connected to the correct connector, the connection is tight), even if you are completely sure that everything is in order with it. Important note: if you have headphones with a microphone with one connector, they require a combined input / output for the microphone and headphones, and this is not available in every PC and laptop.

Checking recording devices

Make sure your microphone is set as the default recording and communication device. For this:

  • In the latest version of Windows 10, right-click on the speaker icon, select Open Sound Options, and on the next screen, select Sound Control Panel under Related Options, then click the Recording tab. In earlier Windows 10 versions, right-click on the speaker icon in the notification area, select “Sounds”, and in the window that opens, open the “Recording” tab.
  • If your microphone appears but is not listed as the default communication and recording device, right-click on it and select Use Default and Use Default Communication Device.
  • If the microphone is listed and already set as the default device, select it and click the Properties button. Check the parameters on the “Levels” tab, try disabling the “Exclusive mode” checkboxes on the “Advanced” tab.
  • If the microphone is NOT displayed, Similarly, right-click anywhere in the list and enable the display of hidden and disconnected devices. is there a microphone among them?
  • If there is a device and is disabled, right-click on it and select “Enable”.

If, as a result of these actions, nothing was achieved and the microphone still does not work (or could not be displayed in the list of recording devices), go to the next method.

Microphone check in device manager

Perhaps the problem is in the sound card drivers and the microphone does not work for this reason (and it also depends on your sound card).

  • Go to the device manager (for this you can right-click on “Start” and select the desired item in the context menu). In Device Manager, open the “Audio Inputs and Audio Outputs” section.
  • If the microphone is not displayed there. we either have problems with the drivers, or the microphone is NOT connected, or is faulty, try to continue from the 4th step.
  • If the microphone is displayed, but you see an exclamation mark near it (it works with an error), try right-clicking on the microphone, select “Delete”, confirm the deletion. Then in the Device Manager menu select “Action”. “Update hardware configuration”. Perhaps after that it will work.
  • In a situation where the microphone is NOT displayed, you can try reinstalling the sound card drivers, for a start. in a simple way (automatically): open the “Sound, game and video devices” section in the device manager, right-click on your sound card, select “Uninstall »Confirm deletion. After uninstalling in Device Manager, select “Action”. “Update Hardware Configuration”. Drivers Will have to be reinstalled and, possibly, after that the microphone will appear in the list again.

If you had to resort to step 4, but this did NOT solve the problems, try installing the sound card drivers manually from the website of the manufacturer of your motherboard (if it is a PC) or laptop specifically for your model (i.e. NOT from the driver-pack and not just “Realtek” and the like from third-party sources).

Microphone does not work in Skype or other software

Some programs, such as Skype, other programs for communication, screen recording, and other tasks, have their own microphone settings. THOSE.

Why the laptop monitor may NOT work?

Often, if a laptop is broken, the monitor does not work. This is Acer, ASUS or LG. The brand is not important, as the malfunctions in computers are usually the same.

Problems are of the following type:

  • The monitor turns gray.
  • The picture is very difficult to see.
  • Image stripes.

  • Burnout of the decoder or failure of the monitor matrix.
  • Graphics card problems.
  • Damaged screen matrix inverter.
  • Backlight problems.

It is also worth remembering that it will not necessarily be a matter of breakdowns. There are hardware reasons why the monitor on a laptop does not work, or it functions too dimly:

  • You accidentally pressed the screen light off key. It is located on one of the function buttons F1 to F12. Most often it looks like a crossed out square. The key can also accidentally stick.
  • You set the brightness level to zero.
  • A hardware or driver error has occurred.
  • You installed the RAM module incorrectly.

Connect an external monitor

If the above tools did not help you, then try to diagnose the laptop by connecting an external monitor to it via the HDMI or VGA connector. Do not forget to check that the computer monitor or TV is also working and is connected to a power source.

If the image is displayed on an external monitor, then there is nothing good about it. Most likely, this means that the cable is damaged in the laptop itself or the screen matrix is ​​broken.

It will be possible to understand what is wrong with your matrix only after testing the entire circuit. In any case, if you do not have experience with laptops, you will definitely not carry out such testing yourself, so you will have to contact the specialists at the service center.

Check the screen off button

The screen off button can also fall in. It is also tied to the F1-F12 keys or is located separately. Sinking can occur when the keyboard is old, or if you spill something sweet on it. You can cope with sinking with a toothpick or fine needle.

If you do not know the parameters of your equipment, the name and model, or you do not want to search for software on the network yourself, trust the updated Windows Center. In this case, the system itself recognizes the device parameters, searches for the required software and installs it. This is possible due to the fact that all developers publish their projects and updates to Windows Update.

An alternative could be any of the third party driver managers. The program will always inform you if an update has been released, and will also be able to find and install the necessary software.
