Discord mic not working
A blocked microphone permission or a wrong Discord input setting often stops the mic. Run the linked mic test first; nothing leaves your device.
Run the test first
Mic test
What the mic test checks
The mic test listens to the microphone and measures its sound level while you speak. It shows whether the page can access a microphone and detect sound from it. It does not test your hearing or prove that Discord can send your voice to other people.
Speak at a normal volume and watch the reading. If it changes while you speak, the microphone is reaching the test. If it stays still, the test may not have access, may not find a microphone, or may be listening to the wrong input.
Tell which case you have
If the test reports that microphone access is blocked, this matches the permission case. Allow Discord to use the microphone in the system, then run the test again.
If the test says no microphone was found, check the plug and hardware mute. On Windows, the page also lists updating the audio drivers and system. If the test detects sound but Discord still cannot hear you, follow the general Discord case: check the selected input, input mode, mute icons, and server permissions, then use Discord's Mic Test and settings reset steps listed on the page.
Why Discord microphone problems happen
The system can block microphone access, so Discord cannot use the device. A loose plug, hardware mute, or a problem with Windows audio drivers or the system can also keep the microphone from appearing.
Discord may have the wrong microphone selected, or its input mode may not suit how you speak. Mute controls or server permissions can prevent others from hearing you even when the mic works in the test. A temporary app problem or changed voice settings can also cause trouble.
When to seek repair or replacement
Try the listed plug and hardware mute checks first. If the system still cannot find the microphone after the listed Windows driver and system updates, the device or its connection may need repair. The page does not list a warranty step, so check the device maker's support information for repair options.
If the test detects your voice but Discord does not, follow the Discord-specific steps on the page before treating the microphone as faulty. A working reading means the test hears sound, but it cannot confirm that every part of Discord's voice connection works.

Run the Mic Test
Press Let's Check and talk. Your voice plays back through the chosen output. If you test while you are in a voice channel, you are muted and deafened until the test ends. It works on desktop and in the browser only.

Check the mute icons and the server permissions
A slash through the microphone or headset icon means your voice is off. If the problem is only in some servers, ask an admin for the Speak permission.

Questions
How do I know if my mic works?
Run the linked mic test and speak. A reading that changes with your voice means the test can detect sound from the selected microphone. It does not confirm that Discord is sending your voice.
Why does the test say no microphone was found?
The microphone may be unplugged, muted by a hardware switch, or unavailable because of a Windows audio driver or system issue. Follow the matching steps shown on the page, then run the test again.
Why does the mic test work but Discord does not?
The test can hear sound while Discord has a different input selected or its input mode, mute controls, or server permissions block voice. Follow the Discord case steps on the page.
Does this test check my hearing?
No. It checks whether the page can hear sound from a microphone. It does not measure hearing or assess hearing health.
What if the reading stays still while I speak?
The page may lack microphone access, may not find a microphone, or may be listening to a different input. Check which case the test reports and follow its matching steps.
