SYMPTOMS

When you use Windows Media Encoder during a Terminal Services session, you may receive the following error message:
No audio input devices detected, therefore live capture options have been disabled.
After you click OK, you receive the following message:
You must have audio codes installed in order to use this application.
In addition, if you are using sound programs which require access to sound cards, you may also receive the same error messages.

CAUSE

This issue occurs because Terminal Services turns off all audio redirection for Remote Desktop Protocol (RDP) clients. Because of Terminal Services' all-or-nothing design, no sound devices are enumerated during a client session. This behavior is by design.

RESOLUTION

To work around this issue, use Microsoft Netmeeting, since this software supports audio devices.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
