Azure Windows VM / Remote Desktop microphone not available to apps like WhatsApp Desktop

Jarvis Ismail 0 Reputation points

Hi, I’m using a Windows VM in Azure and connecting to it over Microsoft Remote Desktop / Windows App and sometimes from a laptop RDP client.

My issue is that apps inside the VM, especially WhatsApp Desktop, say there is no microphone available, even though I have already enabled microphone permissions.

What I’ve already checked:

  • Windows user session is active on the VM
  • Microphone privacy settings are ON:
    • Microphone access = On
    • Let apps access your microphone = On
    • Let desktop apps access your microphone = On
  • Remote Desktop session is active
  • In Windows, I can see Remote Audio at the device layer
  • But inside the usable app-facing audio device list, I mostly only see Voicemeeter / VB-Audio virtual devices
  • Apps like WhatsApp Desktop still behave as if there is no usable microphone
  • I also tested from:
    • Microsoft Remote Desktop / Windows App on phone
    • RDP from laptop
  • Same result on both

How to get a real usable microphone input device into the Azure Windows VM session

    Hi ,

    Thanks for reaching out to Microsoft Q&A.

    RDP microphone works only if audio recording redirection is enabled. Your issue is typically caused by either redirection being off or virtual audio drivers overriding the device.

    Fix:

    1. Enable mic redirection in RDP client
      • Local Resources → Remote audio → Record from this computer
      1. Inside VM
        • Set Remote Audio (Microphone) as default input device
    2. Disable virtual audio drivers (Voicemeeter/VB-Audio)
    3. Check Group Policy
      • Allow audio recording redirection = Enabled

    Note: RDP mic support is unreliable for real-time apps like WhatsApp. For calls, use local machine or Azure Virtual Desktop.
