Discord Mic Not Working? Here's How to Fix It

Q: Why can no one hear me on Discord?

Most commonly: wrong input device selected, mic muted, or Windows/Mac microphone permission denied. Check all three before anything else.

Q: Does Discord mic work in browser vs the desktop app?

Yes — the browser version requires microphone permission from the browser itself in addition to OS permissions. Grant permission when the browser prompts, or check browser Settings → Site Permissions → Microphone.

If your microphone isn't working on Discord, others can't hear you in voice channels or calls. This guide covers every common cause — from incorrect input device selection and OS-level permission denials to hardware conflicts and Discord-specific settings. Solutions work for the Discord desktop app on Windows and Mac, as well as the browser version.

Quick check before anything else: Look at the bottom-left of Discord for the microphone icon. A red diagonal line through it means you're muted. Click it once to unmute. Also check the keyboard shortcut — Ctrl+Shift+M (Windows) or Cmd+Shift+M (Mac) toggles mute instantly and can accidentally silence you.

Introduction: Why Discord Mic Issues Are Common

Frequently Asked Questions

Why can no one hear me on Discord?

Most commonly: wrong input device selected, mic muted at Discord or OS level, or Windows/Mac microphone permission denied. Check the Discord mic icon in the bottom-left first (red line = muted). Then open Discord Voice & Video settings and confirm the correct device is selected in the Input Device dropdown.

Why does my mic cut out during calls?

This is usually caused by Discord's noise suppression incorrectly identifying your voice as noise, or a USB device momentarily losing its connection. Disable Krisp/Noise Suppression in Voice & Video → Advanced settings. If using a USB headset, try a different USB port. For Bluetooth headsets, make sure the headset isn't entering power-save mode mid-call.

Does Discord mic work in browser vs the desktop app?

Yes, but the browser version requires microphone permission from the browser itself in addition to your OS permissions. When you first join a voice channel in the browser, grant permission when prompted. If you accidentally denied it, go to browser Settings → Site Permissions → Microphone → find Discord → Allow.

Why does my mic work in other apps but not Discord?

Discord sometimes uses a different audio API than other apps, particularly on Windows. Try switching Input Mode from Voice Activity to Push-to-Talk in Discord Voice & Video settings. Also check that Windows hasn't set Discord's audio to Hands-Free mode (which has very limited quality) — right-click your microphone in Sound settings → Properties → Advanced tab → ensure the format is set to "16 bit, 48000 Hz (Studio Quality)."

My headset mic works in games but not in Discord — why?

Many gaming headsets with USB connections present themselves as a separate audio device for gaming software and a different one for standard applications. Open Discord Voice & Video settings → Input Device dropdown, and scroll through all available options to find the one that corresponds to your headset specifically (it may be named differently than the gaming software's label). The "Default" option often doesn't pick the right one.

When to Contact Discord Support

If you've worked through all steps above and Discord still can't detect or use your microphone, the issue may be with Discord's backend servers or your account status. Contact Discord support at dis.gd/contact if you have an active Discord Nitro subscription and still experience issues, your account has been flagged for suspicious activity which can sometimes affect voice features, the Discord app is crashing specifically when you try to access voice settings (which can indicate a corrupted installation), or you are experiencing this issue across multiple devices simultaneously (suggesting a server-side issue rather than a device problem).
