Hello @Sarah Williams
Welcome to Microsoft Q&A!
Thank you for your patience, and taking the time to elaborate on your concerns.
Desktop applications cannot access the microphone, even though Windows Voice Recorder and system microphone tests work correctly.
Step-by-Step Troubleshooting.
Step 1: Check Windows Microphone Privacy Settings
- Press Windows + I to open Settings.
On Windows 11, go to Privacy & security → Microphone.
On Windows 10, go to Privacy → Microphone.
Enable Microphone access.
Enable Let apps access your microphone, if available.
Ensure Let desktop apps access your microphone is enabled.
Close and reopen the affected application.
Expected result: The application can access the microphone if privacy settings were the cause.
Step 2: Check Group Policy and Device Management
On managed workstations, Group Policy or mobile device management (MDM) may restrict microphone access.
Open Command Prompt.
Run:
gpresult /h "%USERPROFILE%\Desktop\gpresult.html"
Open the generated report and review the applied policies.
- Check the Windows App Privacy policy named Let Windows apps access the microphone, where applicable.
If the setting is controlled by your organization, contact the IT administrator to review the policy.
Do not bypass organization-managed restrictions.
Step 3: Check Application-Specific Permissions
Open the affected application.
Navigate to its audio, microphone, or device settings.
Select the correct microphone as the input device.
If using a browser, check the microphone permission for the affected website.
Restart the application and test again.
Step 4: Verify Audio Devices and Services
Press Windows + R, enter mmsys.cpl, and press Enter.
Open the Recording tab.
Confirm that the correct microphone is enabled and selected as the default device.
Check the microphone level and mute status.
Open Device Manager using devmgmt.msc and check for audio-device errors.
Open Services using services.msc and confirm that Windows Audio and Windows Audio Endpoint Builder are running.
Step 5: Collect Read-Only Diagnostic Information
Run PowerShell and execute:
Get-ComputerInfo |
Select-Object WindowsProductName, WindowsVersion, OsBuildNumber
Get-CimInstance Win32_SoundDevice |
Select-Object Name, Status, Manufacturer, PNPDeviceID
Get-Service Audiosrv, AudioEndpointBuilder |
Select-Object Name, Status, StartType
Get-ItemProperty `
-Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\AppPrivacy" `
-ErrorAction SilentlyContinue
These commands collect Windows version, audio-device, service, and relevant policy information without intentionally changing system settings.
Recommended Resolution
Follow the steps in order, starting with microphone privacy settings and application permissions. If the problem persists, ask the IT administrator to review Group Policy or MDM restrictions and the affected application's configuration.
Do not modify registry values or change security permissions without authorization. Since the built-in recording and microphone tests work, the issue may be related to application permissions or an organization-managed policy rather than a failed microphone.

Note: Windows 10 standard support ended on October 14, 2025. Confirm whether the workstation is covered by an applicable extended security support program or another supported servicing arrangement.
I hope this helps to better understand the diagnostic options available and the risks involved.
