Complete the following steps on Win 7 and 2008 R2.

  1. First check if RDP- Tcp and ICA- Tcp does not have audio disabled. Go to Administrative tools-> Remote Desktop Session Host Configuration-> RDP-tcp-> Right click-> Properties-> Client Settings. Audio option should be unchecked. Similarly check for ICA-Tcp connection.
  2. Allow Citrix client audio redirection policy in studio console.
  3. Run gpupdate /force on the VDA server.
  4. Verify that Receiver setting for audio is enabled in connection center.
  5. We should be able to get audio working in ICA session.
Steps to be followed on Win 8 and 2012 R2 and above.

  1. Choose Start, choose Run, enter regedit, choose the OK button, and then set the value of the following registry key to 0.
  2. Go to HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\, Edit or create
