The “Error 3002” on Discord is a connection issue that specifically relates to your microphone and voice input. The error means that while Discord recognizes that a microphone is connected to your system, it is unable to detect or transmit any audio from it.
The problem is almost always caused by a misconfiguration on your end, such as a privacy setting, a wrong input device, or a conflicting application.
Step-by-Step Troubleshooting Guide
Follow these steps in order to diagnose and fix the issue:
1. Check Your Windows/macOS Microphone Permissions
Your operating system may be blocking Discord from accessing the microphone. This is the most common cause of Error 3002.
- For Windows:
- Go to Settings > Privacy & security > Microphone
- Make sure that Microphone access is turned on
- Scroll down to the list of apps and ensure that Discord is also enabled
- For macOS:
- Go to System Preferences > Security & Privacy > Microphone.
- Make sure the box next to Discord is checked.
2. Verify Your Discord Voice Settings
Discord might be using the wrong input device or have the wrong settings.
- Open Discord and go to User Settings (the gear icon).
- Go to Voice & Video.
- In the Input Device dropdown menu, manually select your microphone from the list. Do not leave it on “Default”.
- Speak into your microphone. If the green bar next to the input volume moves, you have successfully fixed the issue.
- While in the same menu, try clicking the Reset Voice Settings button at the bottom and restart Discord. This can clear any bad configurations.

3. Troubleshoot Your Audio Drivers and Hardware
If the above steps don’t work, the problem could be with your hardware or its drivers.
- Update Your Drivers: An outdated or corrupted audio driver can prevent your microphone from functioning correctly. Go to your Device Manager (in Windows) or visit the manufacturer’s website for your headset or motherboard to download the latest audio drivers.
- Check Hardware Connections:
- Unplug your microphone or headset and plug it back into a different USB port or audio jack.
- If possible, try using a different microphone or headset to see if Discord recognizes it. This will help you determine if your hardware is faulty.
4. Check for Conflicting Applications
- Disable Noise Suppression: Discord’s built-in noise suppression and echo cancellation can sometimes interfere with your microphone. Go to User Settings > Voice & Video and temporarily disable these settings to see if the issue is resolved.
- Disable Third-Party Audio Software: Other applications like VoiceMeeter, Realtek Audio Manager, or even some antivirus programs can block Discord’s access to your microphone. Temporarily disable these applications to test if they are the cause.
If none of these solutions work, your final step is to completely reinstall Discord and report the issue to Discord’s official support team.
