USB microphone is detected my windows 11, but it is not picking up any audio whatsoever.

Since the microphone is detected in Windows 11 but the input meter never moves, focus on Windows microphone settings and the audio driver stack rather than the USB ports. Based on the steps already tried, use this path:

1. Verify microphone access again in the exact Windows 11 location:
   • Start > Settings > Privacy & security > Microphone
   • Confirm Microphone access is On
   • Confirm Let apps access your microphone is On
   • Confirm Let desktop apps access your microphone is On
2. Test the mic from Windows Sound settings instead of only mmsys.cpl:
   • Start > Settings > System > Sound
   • Under Input, select the Razer microphone
   • Under Input settings, select Start test, speak normally, then Stop test and Play
   • If the recorded sample is silent and the input meter does not move, continue with driver reinstallation
3. Reinstall the audio drivers in Device Manager:
   • Right-click Start > Device Manager
   • Expand Sound, video and game controllers
   • Right-click each audio device listed there and select Uninstall device
   • Check Attempt to remove the driver for this device when available
   • Repeat for other audio devices in that section
   • Restart the PC
   • After restart, if devices do not fully return, open Device Manager, right-click Sound, video and game controllers, and select Scan for hardware changes
   • Then right-click the audio driver and select Update driver
4. If the normal driver path still fails, switch to the generic Windows audio driver:
   • In Device Manager, expand Sound, video and game controllers
   • Right-click the audio device > Update driver
   • Select Browse my computer for drivers > Let me pick from a list of available drivers on my computer
   • Select the audio device/driver offered by Windows and complete the install
5. If this started after Windows changes or updates, roll back the audio driver:
   • In Device Manager, expand Sound, video and game controllers
   • Right-click the audio device > Properties > Driver tab
   • Select Roll Back Driver if available
   • Follow the prompts and restart
6. Make sure Windows is fully updated and then restart again:
   • Start > Settings > Windows Update > Check for updates
   • Install available updates
   • Restart the PC
7. If Windows still detects the mic but captures no audio, run the automated audio troubleshooter in the Get Help app. Microsoft specifically recommends this for Windows 11 audio detection problems.
8. If the issue began after the repair install and none of the driver steps help, use System Restore if a restore point exists from before the problem started. This can undo driver or system changes affecting audio.

About the “Format not supported by the device” message when changing from 48000 Hz to 44100 Hz: that indicates the device does not support that format in the current Windows driver path. It does not by itself prove the microphone hardware is bad.
