My Microphone does not show up as recording device in remote desktop

Old Scenario:

Was incredibly happy with Win7 and sang praises to everyone who would listen on a particular feature of Win7 Remote Desktop.

When working at home on my work laptop.. (small formfactor 1200x800) I was using RDP from my Win7 ULT dekstop into the WIN7 ENT laptop…

Benefits were that I could now use my 30” screen *and* my 24” screen for full desktop usage.

Key benefit was the microphone redirection also as it allowed me to use my desktop surround speakers, and high quality microphone for corporate OCS voice calls locally and internationally.  (Great sound quality)

New Scenario:

My pre-release version of Win7 on my laptop expired, and I re-installed with release version of Win7 ENT

The multiple-screen benefits of Win7 still exist but the microphone redirection no longer works, (despite having the appropriate switch set in the RDP connection)

Microphone works for voice Windows Live calls on the desktop locally.

When RDP-ed to the laptop no “recording device” exists.  When I make OCS voice calls I can hear the other person but no microphone sound is passed through.

Would really appreciate any assistance on troubleshooting this.

Thanks,

Gavin

    Hi A G Williams,

    Since you’re facing this issue after reinstalling Windows 7, audio redirection or bidirectional audio from terminal server to your laptop must be disabled. Contact your IT admin to check if redirecting audio to client terminal services RDP is enabled.

    Also check in your laptop, whether you’re Remote desktop client is configured to support this feature.

    1.     Open Remote Desktop Client

    2.     Click on Remote Audio>settings>Microphone

    3.     Under Microphone, make sure “Record from this computer” is enabled.

    Also check the following link below,

    Hope this information helped you!

    I've managed to resolve the issue through some registry diving. Apologies for not posting it here.

    On the destination (target):

    1. Regedit.exe
    2. HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\
    3. Change fDisableAudioCapture = 0

    This worked for me, although not all applications are able to use this device. If this doesnt work for your specific app, you need to get a USB-over-IP application that can assist you.
