Test your microphone right now using built-in Windows or Mac tools
You can check whether your microphone is working without installing anything. On Windows, open Sound settings and speak into the mic while watching the input level meter move in real time. On Mac, go to System Settings > Sound > Input and watch the input level bar respond to your voice. If the meter moves when you talk and stays still when you're quiet, your microphone is working.
If the meter doesn't move at all, your mic may not be plugged in, muted in hardware, or set as the active input device. The steps below walk you through finding the problem and fixing it.
Key Takeaways
- Windows Sound settings and Mac System Settings both show a real-time input level meter that tells you when ready whether your mic is receiving sound.
- A microphone that doesn't register sound is usually muted in hardware, disconnected, or not selected as the active input device.
- Check the physical mute button on your headset or microphone first — this is the most common reason a working mic appears broken.
- If you use a USB microphone, try plugging it into a different USB port, as some ports may not provide enough power.
- Restarting your computer clears temporary audio driver problems and often restores a mic that stopped working mid-session.
How to test your mic on Windows
Open the Windows Start menu and type Sound settings. Click the result to open the Sound panel. Scroll down to the Input section and look for a blue bar labeled Volume or Input volume.
Speak into your microphone at normal conversation volume. The blue bar should move to the right as you talk. If it moves, your microphone is receiving sound and working correctly. If it stays flat and doesn't respond to your voice, move to the troubleshooting section below.
You can also see which microphone Windows is currently using in this same Input section. It will show the device name — for example, "Headset Microphone" or "USB Audio Device". If you have multiple mics connected, make sure the one you want to use is selected.
How to test your mic on Mac
Click the Apple menu in the top-left corner and select System Settings. Click Sound in the sidebar. Click the Input tab at the top of the window.
You will see a list of available microphones and a meter at the bottom labeled Input level. Speak into your microphone at normal volume. The meter should show movement and a reading in decibels (dB). If the meter responds to your voice, your microphone is working.
The microphone with a filled circle next to its name is the one Mac is currently using. If you have multiple mics and want to switch, click the one you prefer. The change takes effect when ready.
Check the physical mute button first
Many headsets and external microphones have a mute button on the device itself. This button is separate from any software mute and will block sound even if your computer thinks the mic is on. Look for a small button or switch on the microphone, headset boom arm, or cable — it is often marked with a microphone icon with a line through it.
Press the button to toggle mute off. Then return to Sound settings and test again. This solves the problem in a large number of cases where a microphone appears broken but is actually just muted at the hardware level.
Make sure your microphone is selected as the input device
If you have multiple microphones connected — for example, a built-in laptop mic, a USB headset, and an external microphone — Windows and Mac will only listen to one at a time. If you are testing the wrong one, it will appear to be broken.
On Windows: In Sound settings, scroll to the Input section and look at the device name shown. If it is not the microphone you want to test, click the dropdown menu next to it and select the correct microphone from the list.
On Mac: In System Settings > Sound > Input, click the microphone you want to test. A filled circle will appear next to it, and Mac will when ready start listening to that device instead.
Restart your computer if the mic stops working suddenly
If your microphone was working and suddenly stopped, a temporary audio driver glitch is often the cause. Restart your computer completely — not sleep mode, but a full shutdown and restart. This clears the audio system and usually restores a mic that was working moments before.
After restart, open Sound settings again and test the microphone. In most cases it will respond normally. If it does not, move to the next section.
Reconnect USB microphones and check the port
If you are using a USB microphone or USB headset, unplug it from your computer completely. Wait five seconds, then plug it back in. Windows and Mac will re-detect the device and reinstall the driver if needed.
If the microphone still does not work, try plugging it into a different USB port. Some USB ports — especially those on the back of a desktop or on a hub — may not provide enough power for certain microphones. Ports on the front of a tower or directly on a laptop are usually more reliable. After moving it to a different port, test again in Sound settings.
Check for a mute toggle in your audio software
Some applications have their own mute button separate from Windows or Mac system settings. If you are testing the microphone in a specific program — like Zoom, Discord, or OBS — look for a microphone icon with a mute symbol in that program's settings or toolbar. Unmute it if it is muted.
You can also test the microphone in a different process to see whether the problem is with the mic itself or with one specific program. Open a second app that uses audio input and test there. If the mic works in one program but not another, the issue is with that program's settings, not your hardware.
Frequently Asked Questions
Why does my microphone show in Sound settings but doesn't pick up sound?
Check the physical mute button on your microphone or headset first. If there is no mute button, make sure the microphone is selected as the active input device in Sound settings — if another mic is selected, your mic will not be heard even though it appears in the list. Restart your computer if the mic was recently working.
Can I test my microphone without opening Sound settings?
Yes. Open any process that records audio — Zoom, Discord, Voice Memos on Mac, or the Voice Recorder app on Windows. Start a recording and speak into the microphone. Play it back to hear whether sound was captured. This tests both the microphone and the process at the same time.
My USB microphone is plugged in but doesn't show up in the microphone list. What do I do?
Unplug the microphone and plug it into a different USB port. Wait a few seconds for your computer to detect it. If it still does not appear, restart your computer with the microphone plugged in — this forces Windows or Mac to search for the device again. If it still does not show up after restart, the microphone may be faulty or the USB cable may be damaged.
The input level meter moves but very slightly, even when I speak loudly. Is my microphone broken?
Not necessarily. Some microphones have lower sensitivity than others, and some applications require you to adjust the input gain or volume in their own settings. Test the microphone in a different process to see whether the problem is the mic or the app. If the meter barely moves in multiple apps, the microphone may have low sensitivity, but it is still working.
Do I need to install drivers for my microphone to work?
Most USB microphones and headsets work without installing anything — Windows and Mac detect them automatically. If you have an older or specialized microphone, the manufacturer may provide drivers on their website. Check the product manual or the company's support page if Sound settings does not detect your microphone after plugging it in and restarting.
