Welcome to Microsoft Q&A!

Thank you for your detailed information.

Based on your description, because the Plantronics headset no longer appears under either Input or Output in Windows Sound settings, the issue is most likely occurring at the Windows device-detection level rather than simply because an incorrect sound device is selected.

Windows must first detect the physical headset and create the corresponding audio endpoints before the headset can appear as a microphone or speaker under Settings > System > Sound.

One possible cause is that the headset or its audio driver is no longer being detected correctly, has become disabled, or did not load successfully. This can occur after a Windows update, driver change, device reconnection, or a temporary device-enumeration issue.

I recommend allowing Windows to rediscover the headset through Device Manager:

Connect the Plantronics headset directly to the computer and make sure it is powered on.
Select Start, search for Device Manager, and open it.
Expand Sound, video and game controllers and check whether the Plantronics/Poly headset appears.
If the headset is listed but disabled, right-select it and select Enable device.
If it is not listed, select View > Show hidden devices, and then select Action > Scan for hardware changes.
Restart the computer while leaving the headset connected.

After restarting, open Settings > System > Sound and check both Output and Input. If the headset has been detected again, select it as the output device and microphone and, if needed, set it as your default audio device.

If the Plantronics headset still does not appear in Device Manager after scanning for hardware changes and restarting, install the latest compatible headset/audio driver provided by your PC or headset manufacturer, and then restart Windows.

When an audio device is missing or undetected, checking whether the device is detected and enabled in Device Manager, scanning for hardware changes, and installing the latest compatible driver are appropriate troubleshooting steps.

After completing the steps above, check Device Manager and Settings > System > Sound again.

If the headset appears under both Output and Input, play some audio and test the microphone. If both tests succeed, Windows is detecting the headset correctly again and it should also become available to applications.

If the headset still cannot be detected after completing these steps, I recommend opening a Microsoft support ticket rather than repeatedly reinstalling or changing additional system components.

At that stage, further investigation may require diagnostic information that cannot be fully collected or analyzed through the Microsoft Q&A forum, such as device enumeration, driver, or system logs. A support engineer can review that information and help determine whether the problem is related to Windows, the headset driver, or the hardware itself.

If you suspect that the behavior started after a Windows update or represents a reproducible Windows issue, you can also submit it through Feedback Hub. Please include the headset model, Windows version/build, when the problem started, whether it followed an update, and the steps that reproduce the issue. Feedback Hub is useful for reporting reproducible Windows behavior to the Windows engineering team, whereas a support ticket is the better route when you need direct assistance troubleshooting the affected computer.

Reconnect or power on the Plantronics headset, then use Device Manager to reveal and rescan for it before changing the Windows input and output selections.

1. Restore hardware detection

If it uses USB, disconnect it and reconnect it directly to a different USB port rather than through a dock or hub.
Select Start, type Device Manager, and open it.
Select View > Show hidden devices.
Expand:
- Sound, video and game controllers
- Audio inputs and outputs
Select Action > Scan for hardware changes.
If Plantronics, Poly, or a USB audio device appears disabled, right-click it and select Enable device.

Microsoft specifically recommends showing hidden devices and scanning for hardware changes when an audio device is missing ^1^. A different USB port can also restore a USB audio device that is not working ^2^.

If it is Bluetooth rather than USB, confirm that Windows shows it as both paired and connected before proceeding ^3^.

2. Enable both headset endpoints

The headphones and microphone are separate Windows audio endpoints, so check both:

Go to Settings > System > Sound > More sound settings.
On Playback, right-click an empty area and enable:
- Show Disabled Devices
- Show Disconnected Devices
If the Plantronics headphones appear, right-click them and select Enable, then Set as Default Device.
Repeat on the Recording tab for the Plantronics microphone.
Open each device’s Properties and ensure Device usage is set to Use this device (enable) ^4^.

Then return to Settings > System > Sound and select Plantronics under both Output and Input.

3. Reinstall the driver if the headset remains absent

Removing a driver can temporarily affect other audio devices, so uninstall only the Plantronics/Poly or corresponding USB audio entry first.

Open Device Manager > Sound, video and game controllers.
Right-click the Plantronics, Poly, or associated USB audio device and select Uninstall device.
Initially, do not select the option to delete/remove the driver software.
Restart the computer with the headset connected.
If it is not automatically restored, open Device Manager and select Action > Scan for hardware changes.

For a persistent microphone-detection problem, Microsoft’s next recovery path is to uninstall the audio device, restart Windows, scan for hardware changes if necessary, and then update the driver ^3^.

If that fails, install the latest headset driver from the device manufacturer and the latest audio/chipset drivers from the computer manufacturer, then restart. Microsoft recommends the manufacturer’s driver when the installed driver is missing or incompatible ^1^.

4. Verify the result

Output: Play audio and confirm Plantronics is selected under Settings > System > Sound > Output.
Input: Select the Plantronics microphone under Input, run Start test, speak, stop the test, and play the sample ^3^.

If this is Windows Server rather than Windows 10 or 11, provide the exact Server version, headset model, and whether it connects through USB, Bluetooth, or a 3.5-mm jack; the cited procedures are documented for Windows 10 and Windows 11.
