The Logitech G432 is a favorite among gamers thanks to its 7.1 surround sound, comfortable design, and immersive audio. But nothing kills a raid or a squad call faster than your mic suddenly refusing to work. Don't panic! Most microphone issues aren't caused by hardware failure—they're usually down to settings, software conflicts, or outdated drivers. Follow this step-by-step guide, and you'll have your G432 mic working again in no time.
Windows Settings: Your Mic May Be Blocked
Windows can block or misconfigure your microphone without you realizing it. Here's how to fix it:
Select the correct microphone
Press Win + I → System → Sound → Input
Make sure "Logitech G432" is selected
Adjust input levels:
Slide the input volume up and speak to see if the meter moves

Privacy permissions
Go to Settings → Privacy & Security → Microphone
Make sure apps like Discord, Teams, Zoom, and Voice Recorder can access your mic

Disable Exclusive Mode
Right-click the speaker icon → Sounds → Recording → Logitech G432 → Properties → Advanced
Uncheck "Allow applications to take exclusive control of this device"

Gaming App Settings
Sometimes the mic is fine in Windows but blocked or muted in your favorite apps:
Discord: Settings → Voice & Video → Input Device = Logitech G432
Teams / Zoom / Steam: Check input device and volume
Reset settings: Some apps allow you to reset voice input settings—do it and retest
Test in-app: Use the test feature in Discord or Teams to confirm it's working
Drivers: Keep Them Updated (Driver Sentry)
Outdated or corrupted drivers are a major cause of mic issues. Updating them manually can be tricky, but Driver Sentry makes it easy:
Download & install Driver Sentry from the official website
Run the program → Drivers → Scan
The tool will detect missing, corrupted, or outdated audio/mic drivers
Click "Repair Now" or "Update"
Driver Sentry automatically installs the correct driver for your headset and system
Restart your PC and test your mic

Software Conflicts & Background Checks
Other apps may block your microphone:
Close background apps like OBS, Discord, or sound recorders you're not using
Temporarily disable antivirus/firewall software if it's blocking mic access
Restart your PC after making changes and test your mic again

Restart Windows Audio Services
Sometimes Windows audio services can stop working, which can prevent your microphone from functioning. To restart them:
Press Win + R, type services.msc, and press Enter
In the Services window, locate Windows Audio and Windows Audio Endpoint Builder
Right-click each service and choose Restart
Make sure the Startup Type for both is set to Automatic
After restarting, test your microphone to see if it's working properly

Update the Logitech G432 Firmware
Firmware updates can help fix microphone and audio problems on your Logitech G432 headset. To update your device:
Open the Logitech G Hub software on your PC
Ensure your Logitech G432 is connected properly
Check for available firmware updates. If an update is detected, follow the instructions on screen to install it
Once the update is complete, restart your computer and test the headset's microphone

Reset the Logitech G432 (Factory Reset)
If the microphone still isn't working after updating the firmware, performing a factory reset may solve the issue:
Press and hold the power button for 10–15 seconds (refer to the manual if needed)
Reconnect or re-pair the headset with your PC or console
Test the microphone again to see if it is now functioning correctly

Conclusion
Most issues are fixed with these steps—so stay calm, follow the guide, and you'll be back in the game or voice chat in minutes. Your Logitech G432 mic should now be working perfectly, letting you enjoy crystal-clear communication during gaming, streaming, or meetings.
