Symptoms

Windows 7 and Windows Server 2008 R2 let you redirect your audio recording device to a Remote Desktop session by using Remote Desktop Connection and the Audio Recording Redirection feature.

Note The Audio Recording Redirection feature is not available in Windows Professional edition.

For more information about how to configure Windows Server 2008 R2 to redirect an audio signal, go to the following Microsoft TechNet website:

http://technet.microsoft.com/en-us/library/dd759231.aspx

This same configuration might be useful in a VDI Scenario in which you connect to a virtualized Windows 7 desktop.

In Windows 7, the Allow audio recording redirection policy does not have to be enabled to allow audio recording redirection. However, if you set the policy to Disabled, the Audio Recording Redirection option is disabled.

Cause

Resolution

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

The following registry subkey can disable the Audio Recording Redirection feature:

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

fDisableAudioCapture REG_DWORD 0 | 1

If either the policy or registry subkey on the Windows 7 Remote desktop computer are set to Disabled, Audio Recording Redirection is not available.

In Windows 7 Enterprise Edition, this registry subey is set to 1 by default. Therefore, Audio Recording Redirection is not available.

In this case it would not help to set the policy value to Enabled. Instead, you must set the subkey to 0.
