Why is RDP microphone redirection not working?

RDP (Remote Desktop Protocol) has been really helpful for people who work at home. With RDP, people can access transfer important files on their office computer or provide remote support for their clients. RDP also enables users to have remote meetings with their colleagues. But sometimes, problems such as remote desktop no sound may happen. This problem probably is caused by RDP microphone redirection not working.

Feedback from users includes that they are able to connect to a Windows 10 Pro Creators update host using RDP, and they can see the “Remote Sound” icon in the tray and it shows when audio is playing with the volume bar, however, the hosts sound is not transmitted to the RDP session.

So what causes the RDP microphone redirection not working windows 10 issue? Here in this post, the top four possible causes are listed. It may be because of Remote Desktop Connection settings. If Remote audio playback is set to “Do not play” or Remote audio recording is set to “Do not record”, then RDP microphone redirection may not work correctly. It may also be caused by improper Group Policy setting, Registry setting, and Services setting.
