Mic Not Working on Discord? How to Fix It

By Jayadeep · Updated June 2026

Quick answer: On Discord, a silent mic is usually the wrong input device, an input-sensitivity slider set too high, or push-to-talk being on. Pick your mic in Voice settings, adjust the sensitivity, and check your input mode.

Confirm the mic works at all: open the microphone test and speak.

Fix it inside Discord

Open Settings, then Voice and Video. Set Input Device to your actual microphone, and under Input Sensitivity toggle automatic off and speak to see the bar move. Check Input Mode — if Push to Talk is on, you must hold the key. If all else fails, scroll down and use Reset Voice Settings.

Check Windows permission and device

Make sure Discord is allowed under Settings, Privacy and security, Microphone, and that your mic is the default input in Windows sound settings.

Disable exclusive mode

If another program grabbed the mic, Discord gets nothing. In the classic Recording properties, on the Advanced tab, untick the exclusive-mode options, then restart Discord. For deeper system issues see our guide on a microphone not working on Windows 11.

Confirm it works

Use Discord's own mic test in Voice and Video, or re-run the microphone test, then rejoin a voice channel.

Discord-Specific Decision Path

If your mic bar never lights up, Discord has the wrong Input Device or Input Sensitivity is set too high — go to User Settings → Voice & Video, pick your device, and watch the Mic Test bar. If you cut in and out, switch Input Sensitivity from Automatic to manual and drag the threshold left. If push-to-talk does nothing, your keybind may be unset or captured by another app. If the mic passes the microphone test but fails only in Discord, the problem is a Discord setting, not your hardware.

Edge Cases and Fixes Competitors Miss

Discord's exclusive-mode and audio-subsystem settings cause many "ghost" failures: switching the Audio Subsystem from Standard to Legacy under Voice & Video resolves a surprising number of cases, especially with USB headsets. The browser version of Discord needs its own microphone permission via the address-bar lock icon, separate from the desktop app. And Discord's automatic gain control and noise suppression (Krisp) can over-aggressively cut a quiet voice — turning noise suppression down often brings a faint mic back to life. Running Discord as administrator can also fix push-to-talk that won't register in games.

Discord Voice Settings That Matter Most

Discord gives you more audio controls than most apps, and the wrong combination is usually the culprit. Under User Settings → Voice & Video, set Input Device explicitly rather than leaving it on Default, since Default follows Windows and can drift to the wrong mic. Set Input Mode to Voice Activity for hands-free or Push to Talk for noisy rooms, and if Voice Activity, switch Input Sensitivity to manual and drag the bar so your normal speech lights it but silence doesn't. Lower noise suppression (Krisp) if a quiet voice keeps getting cut. And the Audio Subsystem setting at the bottom — switching Standard to Legacy — fixes a remarkable number of "my mic just stopped" cases, especially with USB headsets.

Reset Steps and Edge Cases

When settings alone don't work, a clean reset usually does: in Voice & Video, scroll down and click "Reset Voice Settings," then reselect your input device. On the desktop app, running Discord as administrator fixes push-to-talk keys that won't register while you're in a full-screen game. The browser version needs its own microphone permission from the address-bar lock icon, separate from any desktop app. And if you joined a call before plugging in a headset, Discord sometimes keeps the old device — disconnect and rejoin the voice channel so it picks up the new mic. As always, confirm the hardware itself with the microphone test before blaming Discord.

Discord on Mobile and in the Browser

On the Discord mobile app, microphone access is granted at the OS level — if calls are silent, open your phone's Settings → Discord → Microphone and enable it, then fully close and reopen the app. In a voice channel, check you haven't muted yourself with the mic icon at the bottom. In Discord on the web, the browser must grant mic permission through the address-bar lock icon, which is entirely separate from the desktop app's settings, so a working desktop app tells you nothing about the browser version.

When It's Not Discord at All

Before spending more time in Discord's menus, confirm the hardware with the microphone test. If the meter is flat there too, the problem is your device, permissions or driver at the system level, and no Discord setting will fix it — sort the mic out in Windows or macOS first. If the test meter moves but Discord stays silent, then it genuinely is a Discord setting, and the input device, sensitivity, audio subsystem and reset steps above are where the fix lives. Separating "is it the hardware or the app" this way saves the most time, because the two have completely different solutions.
