Published: January 8, 2010

yellow

Remote Desktop Connection (RDC) 7.0 and Windows Server 2008 R2 support bi-directional audio redirection by efficiently transporting audio-based multimedia in a compressed format within the RDP protocol. If the client supports bi-directional audio redirection, it will receive the original compressed audio stream from the server and decode it on the client computer.
