Microsoft Terminal Services on WS2008R2 drops Audio Mapping in RDP after some time.


  • Hello,

    We have a client using Server 2008 R2 with a Terminal Services environment. The environment is set up to allow audio redirection back to the client via RDP and the client's RDP connection file has 'Bring to this machine' checked.

    Sound will map correctly when they do their initial connection and will work through Windows Media Player and Quicktime just fine. We have installed the Desktop Experience pack on the servers to get the ability to play sound through Windows Media Player.

    After some time, usually 1-3 hours into a session that is not idle long enough to become disconnected or logged off automatically, the sound will stop playing and Windows Media Player will display a message stating that there is no device for which to play sound through. At the same time, the volume slider is at the top, when you click it, there is no sound, and Quicktime also does not play sound although there is no error like in WMP.

    The volume slider on the users local PC plays sound when you click it and can play the same file (stored on a network drive via DFS and Folder Redirection in Group Policy) with no issues.

    Disconnecting the session without logging off, then logging back onto the same session plays sound again.

    Can you please give me some things to check?

  • Hello Patrick,

    When the issue occurs, have you checked the Event Viewer on the server side? The Application category may contain the clue to describe why the sound is not redirected correctly.

  • There actually isnt anything pertaining to this in the Event Logs. Unfortunately. I had to wait for the issue to happen again and then check at the time it happened.


    Anything else? :(
