Why Is My Discord Mic Not Working on Windows 10?

Before jumping into fixes, it’s helpful to understand the common causes:

Incorrect input device selection: Discord or Windows may be using the wrong microphone, especially if you have multiple audio devices connected.
Disabled microphone permissions: Windows 10 privacy settings or Discord’s app permissions may block microphone access.
Outdated or corrupted audio drivers: Drivers are essential for hardware communication, and outdated or faulty drivers can cause mic issues.
Discord settings misconfiguration: Wrong input sensitivity, voice activity mode, or disabled microphone in Discord’s settings can mute your voice.
Windows 10 updates or conflicts: Recent updates, conflicting software, or background apps (like other voice chat programs) can interfere with Discord’s microphone access.
Hardware or connection issues: A loose cable, damaged mic, or incorrect port can prevent Discord from detecting your microphone.
Discord’s advanced features: Features like Krisp noise suppression, QoS (Quality of Service), or Streamer Mode can sometimes disrupt microphone functionality.

Step 1: Check Your Microphone Hardware

Start with the basics to rule out physical issues:

Ensure your microphone is properly connected. If using a USB mic, try a different port. For 3.5mm jacks, ensure it’s plugged into the correct pink port.
Test your mic on another device or app. Open Windows’ built-in Voice Recorder (search for it in the Start menu) and record a short clip. If it works, the issue is likely with Discord or its settings.
Check for mute buttons. Some microphones and headsets have physical mute switches—make sure yours isn’t activated.
Try a different microphone. If possible, test another mic to determine if the problem is with your hardware or software.

Step 2: Select the Correct Microphone in Discord

Discord may not be using the microphone you intend. Here’s how to check and change it:

Open Discord and click the gear icon (User Settings) near your username.
Navigate to Voice & Video in the left sidebar.
Under Input Device, select your microphone from the dropdown menu. If you’re unsure which one to pick, try each option while speaking to see which one responds.
Adjust the Input Volume slider to ensure it’s not set too low.
Click Let’s Check to test your microphone. If the green bar moves as you speak, Discord is detecting your mic.

Step 3: Enable Microphone Access in Windows 10

Windows 10 has strict privacy controls that can block apps from using your microphone. Follow these steps to grant Discord access:

Press Win + I to open Settings, then go to Privacy > Microphone.
Ensure Microphone access for this device is turned On.
Scroll down to Allow apps to access your microphone and toggle it On.
Further down, ensure Allow desktop apps to access your microphone is also On.
Restart Discord and test your mic again.

If Discord still doesn’t detect your mic, proceed to the next step.

Step 4: Set Your Microphone as the Default Device in Windows

Windows may be using a different default input device. To fix this:

Right-click the speaker icon in your taskbar and select Open Sound settings.
Under Input, select your microphone from the dropdown menu.
Click Device properties and ensure the Disable option is turned Off.
Go to the Sound Control Panel (search for it in the Start menu), right-click your microphone, and set it as the Default Device and Default Communication Device.

Step 5: Update or Reinstall Audio Drivers

Outdated or corrupted drivers are a common cause of microphone issues. Here’s how to update them:

Press Win + X and select Device Manager.
Expand Audio inputs and outputs, right-click your microphone, and select Update driver.
Choose Search automatically for updated driver software and follow the prompts.
If updating doesn’t work, right-click your microphone again and select Uninstall device. Restart your PC—Windows will automatically reinstall the driver.
For best results, visit your motherboard or sound card manufacturer’s website and download the latest drivers manually.

Step 6: Disable Exclusive Mode and Audio Enhancements

Windows’ exclusive mode and audio enhancements can interfere with Discord. To disable them:

Right-click the speaker icon in your taskbar and select Sounds.
Go to the Recording tab, right-click your microphone, and select Properties.
Navigate to the Advanced tab and uncheck Allow applications to take exclusive control of this device.
Go to the Enhancements tab and check Disable all sound effects.
Click Apply and OK, then restart Discord.

Step 7: Reset Discord’s Voice Settings

Resetting Discord’s voice settings can resolve hidden configuration issues:

Open Discord and go to User Settings > Voice & Video.
Scroll down and click Reset Voice Settings.
Confirm the reset and restart Discord.
Reconfigure your microphone and test it again.

Step 8: Disable Discord’s Advanced Voice Activity and QoS

Discord’s advanced features can sometimes cause microphone problems. Try disabling them:

In Discord, go to User Settings > Voice & Video.
Under Voice Activity, disable Automatically determine input sensitivity and manually adjust the slider.
Turn off Enable Quality of Service High Packet Priority in the Advanced section.
If using Krisp noise suppression, switch to Standard or None.

Step 9: Run the Windows Audio Troubleshooter

Windows includes a built-in tool to diagnose and fix audio issues:

Go to Settings > Update & Security > Troubleshoot.
Select Recording Audio and click Run the troubleshooter.
Follow the on-screen instructions and apply any recommended fixes.

Step 10: Close Conflicting Applications

Other apps using your microphone (e.g., Skype, OBS, or background processes) can conflict with Discord. Close all unnecessary programs and test your mic again. If the issue persists, try running Discord as an administrator:

Right-click the Discord shortcut and select Run as administrator.
Test your microphone in a voice channel.

Step 11: Reinstall Discord

If all else fails, a fresh install of Discord can resolve deep-seated issues:

Uninstall Discord via Settings > Apps > Apps & features.
Download the latest version from Discord’s official website.
Install Discord and log back in. Configure your microphone settings as described earlier.

Step 12: Check for Windows Updates

Microsoft frequently releases patches for audio-related bugs. Ensure your system is up to date:

Go to Settings > Update & Security > Windows Update.
Click Check for updates and install any available updates.
Restart your PC and test your microphone in Discord.

Pro Tips for Optimal Discord Microphone Performance

Use Push-to-Talk for noisy environments: Enable Push-to-Talk in Discord’s voice settings to avoid background noise triggering your mic. Assign a key (e.g., Ctrl or Alt) for easy access.
Adjust input sensitivity: If your mic picks up too much background noise, lower the input sensitivity in Discord’s voice settings. If it’s too quiet, increase it slightly.
Monitor your mic in real-time: Enable Echo Cancellation and Noise Suppression in Discord’s voice settings for clearer audio.
Avoid Bluetooth mics for gaming: Wired microphones offer lower latency and more reliable performance for voice chat.
Regularly update drivers: Set a reminder to check for audio driver updates every few months to prevent future issues.
Test in a private call: Before joining a group call, test your mic in a private Discord call with a friend to ensure everything works.
