How do I get my microphone to work through Remote Desktop?


I'm trying to provide remote support to one of my clients via Remote Desktop (RDP) but only find the microphone is not working, which is quite inconvenient. Are there any suggestions that could help me get my microphone to work through Remote Desktop?"

- Question from Alex

For countless remote workers who need to remote into work computers from home, accessing Windows-based remote desktops is an integral part of their daily work routine. Having a properly functioning microphone can significantly boost user productivity. However, when RDP microphone redirection not working properly, it can be incredibly frustrating. 

Why is RDP microphone redirection not working?


Several aspects within the Remote Desktop Protocol (RDP) configuration play a pivotal role in microphone functionality. Here are the three most common factors:

  • Microphone status on the local device: The microphone on the user's device must work properly. If not, it may be due to connectivity or driver issues.
  • Local device and microphone connection type: The type of connection, like Bluetooth or USB, can affect microphone performance within an RDP session.
  • RDP settings affecting microphones: Various RDP settings, including end-user device configurations and Group Policies, can influence microphone behavior during RDP sessions.
