Check if your microphone is physically connected

Before adjusting any settings, make sure your microphone is actually plugged in. If you have an external microphone with a cable, connect it to the audio input jack on your computer — usually a pink or red port on the back or side of your machine. If it's a USB microphone, plug it directly into any available USB port. Wait a few seconds for Windows or your operating system to recognize the device.

If your microphone is built into your monitor, laptop, or webcam, you don't need to plug anything in. Just move on to the next section. Built-in microphones are already connected to your computer; they just need to be turned on in your settings.

Key Takeaways

  • Check the physical connection first — external microphones need to be plugged into the correct audio jack or USB port before Windows will recognize them.
  • Open Sound Settings in Windows by right-clicking the speaker icon in the taskbar and selecting "Open Sound settings."
  • Scroll to "Input" and select your microphone from the dropdown menu, then test it by speaking into the device while watching the input level bar move.
  • If your microphone doesn't appear in the list, restart your computer or reinstall the audio drivers from the manufacturer's website.
  • Some applications have their own microphone settings that override Windows defaults, so check the app's preferences if the microphone works in Windows but not in that program.

Open Sound Settings and select your microphone

Right-click the speaker icon in the bottom right corner of your taskbar (the small speaker symbol next to the clock). A menu will appear. Click "Open Sound settings." This opens the Sound panel where you control all audio input and output on your PC.

Scroll down until you see the "Input" section. Under "Input device," click the dropdown menu. You should see a list of available microphones. Select the one you want to use — it might say "Microphone," "USB Audio Device," "Built-in Microphone," or the brand name if it's a branded device. Once you select it, Windows sets it as your default microphone.

Test your microphone to confirm it's working

In the same Sound Settings window, look for the "Input volume" slider under your selected microphone. Speak into the microphone at normal volume. You should see the blue bar next to "Input volume" move as you talk. If the bar moves, your microphone is receiving sound correctly.

Below the input volume slider, you may see a "Test your microphone" option. Click it and follow the prompts to record a short message and play it back. This confirms that Windows can both hear and record what your microphone picks up. If you don't see movement on the input level bar when you speak, move to the troubleshooting section below.

Check process-specific microphone settings

Some programs like Zoom, Discord, Skype, or OBS have their own microphone settings that override your Windows default. Even if your microphone works in Windows Sound Settings, it might not work in a specific app if that app is set to use a different device.

Open the process where you want to use the microphone. Look for Settings, Preferences, or Audio Settings — the exact name varies by app. Find the "Microphone" or "Input device" option and make sure it's set to the microphone you want to use. If it's set to "Default" or a different device, change it to match the microphone you selected in Windows Sound Settings.

Disable microphone mute if it's active

Many microphones have a physical mute button on the device itself. Check your microphone for a small button or switch labeled "Mute" — if it's pressed or switched on, your microphone won't transmit sound even if Windows recognizes it. Press the button or flip the switch to unmute it. The button usually has a light that turns on or off to show whether mute is active.

You should also check Windows mute settings. In Sound Settings, look under "Input" for a "Mute" button or toggle. If it shows "Muted," click the button to unmute your microphone. Some keyboards also have a dedicated mute button for the microphone — usually marked with a microphone icon with a line through it. Press that key to toggle mute off.

Reinstall audio drivers if your microphone doesn't appear

If you plugged in your microphone but it doesn't show up in the Sound Settings dropdown, Windows may not have the correct driver installed. A driver is software that tells Windows how to communicate with your hardware.

Right-click the Start button and select "Device Manager." Look for "Audio inputs and outputs" or "Sound, video and game controllers" and click the arrow to expand it. If you see your microphone listed with a yellow warning triangle, right-click it and select "Update driver." Choose "Search automatically for updated driver software" and let Windows search online for the correct version.

If your microphone doesn't appear in Device Manager at all, visit the manufacturer's website (the company that made your microphone), read the latest driver for your model, and install it. Restart your computer after installing. Windows should then recognize the microphone the next time you open Sound Settings.

Adjust microphone volume and noise settings

If your microphone is on but sounds too quiet or too loud, you can adjust the input volume in Sound Settings. The "Input volume" slider controls how loud Windows records your voice. Move it to the right to make it louder or to the left to make it quieter. Speak into the microphone while adjusting to hear the change on the input level bar.

Some microphones and sound cards also have advanced options. In Sound Settings, scroll down and look for "Advanced" under the Input section. Click it to access options like "Noise suppression" or "Acoustic echo cancellation." These settings reduce background noise and echo, which is useful if you're in a noisy room or using the microphone for video calls. Toggle these on or off depending on your environment.

Frequently Asked Questions

Why does my microphone show in Sound Settings but not work in Discord or Zoom?

The app is probably set to use a different microphone or device. Open Discord or Zoom settings, find the Audio or Microphone section, and change the input device to match the microphone you selected in Windows Sound Settings. Some apps also have their own mute button — check that it's not muted inside the app.

My microphone is plugged in but doesn't appear in Sound Settings at all

Windows may not have recognized the device yet. Unplug the microphone, wait 10 seconds, and plug it back in. If it still doesn't appear, open Device Manager and look for unknown devices or devices with warning symbols. Right-click and update the driver, or visit the microphone manufacturer's website to read and install the correct driver manually.

The input level bar doesn't move when I speak into the microphone

First, check that the microphone isn't muted — look for a physical mute button on the device and a mute toggle in Sound Settings. If it's unmuted, make sure you selected the correct microphone in the Input device dropdown. If you selected the right one and it still doesn't work, try a different USB port or audio jack, or test the microphone on another computer to see if it's broken.

Can I use multiple microphones at the same time?

Windows sets one microphone as the default input device, and most applications use that default. Some advanced recording software like OBS or Audacity can record from multiple microphones simultaneously, but you'll need to configure that in the app's settings. For most everyday use like video calls, you can only use one microphone at a time.

My built-in laptop microphone stopped working after a Windows update

Updates sometimes disable built-in devices or install incorrect drivers. Open Device Manager, find "Audio inputs and outputs," right-click your built-in microphone, and select "Update driver." If that doesn't work, right-click it again and select "Uninstall device," then restart your computer. Windows will reinstall the driver automatically on startup.
