Few things are more frustrating than joining a Discord call and realizing nobody can hear you. If your Discord mic is not working, the problem is usually not your microphone itself. It is almost always a settings issue, a permissions problem, or a device conflict.
This guide walks through every common fix, from quick checks to deeper system-level solutions. Start at the top and work your way down. Most people fix the issue within five minutes.
Step 1: Make sure Discord is using the right microphone
This sounds obvious, but it is the most common cause.
- Open Discord
- Go to User Settings
- Click Voice & Video
- Under Input Device, select the microphone you actually use
- Speak and watch the Input Sensitivity bar
If the bar does not move, Discord is listening to the wrong device.
Tip: Do not leave the input device set to “Default” if you have multiple mics, headsets, or webcams.
Step 2: Check if your mic is muted in Discord
Discord has more than one mute state.
Check all of these:
- Bottom-left mic icon is not muted
- You are not server-muted by a moderator
- You are not locally muted by yourself
- Push-to-talk is not enabled by accident
Push-to-talk trips up a lot of users. If it is enabled, Discord will not transmit unless you hold the assigned key.
Step 3: Test your mic outside Discord
Before changing deeper settings, confirm the mic actually works.
On Windows:
- Open Sound Settings
- Go to Input
- Speak and check if the level moves
On macOS:
- Open System Settings
- Go to Sound > Input
- Select your mic and speak
If the mic does not work here either, the issue is hardware, drivers, or permissions.
Step 4: Check microphone permissions
Windows microphone permissions
- Open Settings
- Go to Privacy & Security
- Click Microphone
- Make sure:
- Microphone access is enabled
- Apps are allowed to access the microphone
- Desktop apps are allowed
macOS microphone permissions
- Open System Settings
- Go to Privacy & Security
- Click Microphone
- Make sure Discord is checked
If Discord is not listed, restart Discord and try again.
Step 5: Disable Discord audio enhancements
Audio processing can break mic input, especially with USB headsets.
In Voice & Video settings:
- Turn off Noise Suppression
- Turn off Echo Cancellation
- Turn off Automatic Gain Control
- Disable Advanced Voice Activity
Restart Discord after changing these.
If your mic suddenly works, re-enable features one by one.
Step 6: Reset Discord voice settings
If things feel completely broken, reset everything.
- Go to Voice & Video
- Scroll down
- Click Reset Voice Settings
- Restart Discord
This clears misconfigured input, sensitivity, and processing settings.
Step 7: Check for app conflicts
Other apps can steal mic access or change device priority.
Common culprits:
- OBS
- Zoom
- Teams
- NVIDIA Broadcast
- Voice changers
Close them completely and test again.
If you use AI voice tools or voice bots, make sure they are not routing audio incorrectly.
For example, if you are experimenting with voice features like CopyKitten, double-check that your system microphone is still selected as the input device and not a virtual audio cable.
Step 8: Browser Discord mic not working
If you use Discord in a browser:
- Make sure the browser has mic permission
- Check the site permissions icon in the address bar
- Try another browser
- Disable extensions that affect audio or privacy
Chrome and Edge usually work best for Discord web.
Step 9: Update Discord and your audio drivers
Outdated software can cause mic failures.
- Restart Discord fully (not just minimize)
- Check for Discord updates
- Update your audio drivers
- Restart your computer
A reboot fixes more Discord mic issues than people want to admit.

FAQ: Discord mic not working
Why does my mic work everywhere except Discord?
Usually, Discord is set to the wrong input device or lacks microphone permission at the system level.
Does Discord block microphones?
No, but it relies heavily on system permissions and device priority.
Can bots affect my microphone?
Most bots cannot directly access your mic, but virtual audio setups, voice changers, or AI voice tools can change routing if misconfigured.
Final thoughts
When your Discord mic is not working, the fix is almost always a setting, not broken hardware.
Start simple:
- Check input device
- Check mute states
- Check permissions
Then move into enhancements, resets, and app conflicts.
Once your mic is working again, you can get back to what Discord is actually for: talking with people, gaming together, or experimenting with fun voice tools like CopyKitten without yelling “can you hear me?” for ten minutes straight.
