If Discord can't detect your mic, the input list is either empty or pointed at the wrong device, and the fix sits in two places: Discord's Voice and Video menu and Windows' microphone privacy switch. Check both in that order, restart Discord, and speak while watching the input meter to prove it works.

Quick Answer

In Discord open User Settings, Voice and Video, and choose your microphone under Input Device. In Windows, turn on microphone access in the privacy settings. Untick exclusive mode in the Sound control panel if another app has grabbed the mic. A full Discord restart after changing devices fixes many cases.

🎙️ Pick the right device inside Discord

Click the cog beside your name, open Voice and Video, and look at Input Device. If it says "Default", change it to the exact name of your headset or microphone. Say something and watch the "Let's Check" meter or the Mic Test bar. If it moves, Discord can hear you.

If the list is empty or the meter stays flat, scroll down in the same menu and choose Reset Voice Settings. Reselect the input, then test again. Also check the input volume slider is not at zero, and that "Automatically determine input sensitivity" is on while you troubleshoot.

🔒 Windows privacy and device status

Discord depends on Windows letting it through. On the Windows microphone privacy page, the main access switch and the app switch must be On, and desktop apps must be allowed too.

Next, open Sound settings from the taskbar and look under Input. A disabled microphone shows in the list with a "Don't allow" or disabled marker. Open More sound settings, Recording, right-click empty space and tick Show disabled devices, then enable your mic.

Exclusive mode conflicts

In the Recording tab, double-click the microphone, open Advanced, and clear the exclusive control tickbox. That lets Discord share the microphone with a recording tool or a game.

🔌 Hardware, ports and the web app

Before anything else, unplug the microphone, wait five seconds and plug it back in while Discord is open. Discord builds its device list when the app starts and when hardware changes, so a mic connected during a call sometimes needs that nudge. If it still does not appear, close Discord from the system tray, not just the window, and reopen it.

A USB microphone should show up as its own device. Try a different port, preferably a rear USB 3 socket, and skip unpowered hubs, since they can drop the connection. A 3.5mm headset needs the correct jack; laptops with one combo jack need a four-pole plug, and a plain mic plug will not send audio.

If you use the Discord web version in a browser, you must also allow the microphone for the site. Click the padlock beside the address, set Microphone to Allow, and reload the page. Browsers keep this permission separate from Windows, so both need to be on.

Bluetooth headsets add another trap. Windows may be connected in stereo mode only, and the Hands-Free entry must be selected as the input for the mic to work.

🌍 Rule out the connection

Sometimes Discord detects the mic perfectly and the problem is that no one hears you. Over South African LTE or a congested fibre line, voice packets can drop and make a working microphone seem broken. Check that your friend can hear you in a short test, or use the Discord echo bot's voice check.

If the microphone really is the weak point, replacing it is cheap. Look at the streaming essentials category for microphones from roughly R200 upwards, and browse webcams if you also stream your face.

Frequently Asked Questions

Where do I choose my microphone in Discord?

Open User Settings, Voice and Video, and use the Input Device drop-down. Speak and watch the input meter; if it moves, Discord can hear that device.

Why does Discord show no input device at all?

Windows may be blocking microphone access, or the device is disabled. Check Settings, Privacy and security, Microphone, and Sound settings for a disabled input.

What is exclusive mode and can it cause this?

Exclusive mode lets one app take control of a device. In Sound, Properties, Advanced, untick it so Discord and other apps can share the microphone.

Will resetting voice settings help?

It can. In Voice and Video, scroll down and choose Reset Voice Settings, then reselect your input and run the Mic Test again.

Does the web version behave differently?

Yes. In a browser you must allow microphone access for the Discord site through the padlock in the address bar, in addition to the Windows setting.

What if only a USB mic fails?

Try another port and skip unpowered hubs. Also confirm the connection is up, since a patchy South African LTE or fibre line can look like a mic fault.
