App Permissions for Microphone

Seems there is no GPO nor registry setting that can pre-authorize microphone/camera access but some workarounds:

1. Use Group Policy to Enable Microphone Access Globally

• Navigate to:
  Computer Configuration > Administrative Templates > Windows Components > App Privacy
• Enable:
  Let Windows apps access the microphone
  Let desktop apps access the microphone

This won’t auto-approve Teams VDI specifically, but it ensures microphone access is generally allowed.

2. Scripted Registry Injection (Advanced)

You can pre-populate registry keys for known Teams VDI app paths:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore\microphone]

"MicrosoftTeamsVDI.exe"="Allow"

3. Use a Stable Teams VDI Deployment

• Avoid frequent updates unless necessary.
• Use machine-wide installation to reduce duplicate entries.

4. Monitor and Clean Up Old Entries

• Periodically check Settings > Privacy & Security > Microphone for redundant Teams VDI entries.
• Remove outdated ones to reduce confusion.
