Rdesktop microphone

On desktop Windows clients, the mic setting is in the "new connection" dialog, under Local Resources / Remote audio [Settings...] / Remote audio recording: Record from this computer.

However, it sounds like you're trying to record audio on the remote computer, which is not an available option for the native clients. It's possible that other clients can support this feature, but it may also be a limitation of RDP, which would make it impossible.

Use the following steps to address the problem of a microphone not working through RDP.

     1. Enable Windows Audio Service

Open Control Panel -> System and Security

Select "Administrative Tools" or "Administration"

Start "Services" on your Windows machine.

Locate and right-click on the "Windows Audio" icon and select Properties

In the settings window that opens, you set the Startup Type to “Automatic”. This ensures that the audio service will be started automatically each time the system restarts.

Once the configuration is complete, start the service by selecting "Windows Audio" and click “Run” or “Start”.

     2. Enable audio redirection in server properties

If the problem is that your microphone over RDP in Windows 10 is not working, you need to access and modify the server properties. Press Win + R and type the command GPEDIT.MSC. Press OK or Enter to run the command.

In the new window that appears, select Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Device and Resource Redirection -> Allow Audio and Video Playback Redirection.

Under Remote Desktop Services or Device and Resource Redirection, there are two policies that may be the reason your microphone stops working after a few seconds on RDP. You want to click Allow or Enable on both of the following policies.

• Allow audio and video playback redirection.
• Allow Audio Recording Redirection.

     3. Update Register Parameters.

On a Windows machine press the keyboard shortcut Win + R and execute the REGEDIT command.

We can now verify that both policy rules are indeed enabled as we need. In the new window that opens, navigate to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-TCP.

Open the file so it can be edited.

Insert "00000000" in the small window that appears to replace its current value of “0 and click OK.

     4. Final Windows Settings

1. Start the Remote Desktop Connection application.
2. Enter the IP address of the server in the General tab.
3. Go to Local Resources -> Options tab and check the Play on this computer and Record from this computer boxes in the displayed window.
4. Click OK and Connect.
   

This should resolve the problem of your microphone not working in an RDP session.
