Port 3389 is the only port you need to open. Windows will attempt to stream sound through User Datagram Protocol (UDP) first. If no port is available for UDP, sound will stream through a virtual channel in Remote Desktop Protocol, which uses port 3389.

Remote Desktop Protoco or RDP, is part of Windows Terminal Server and Windows NT multichannel conferences and uses default port 3389. RDP was designed to be able to view remotely and offer data for applications running on a remote computer in Windows. Supported clients include Windows 95/98/Me and Windows NT/2000/XP operating in the ROF RDP Laye implementation of the OSI model.

The Internet Assigned Numbers Authority (IANA) maintains and assigns port numbers to specific software manufacturers need to use the communications protocols in its software.

There are rare instances in which the port number Remote Desktop need changing. If no other application under the rules of the IANA uses port 3389, Remote Desktop can not function properly. In this case, to use Remote Desktop, you must change the port number. Use the port number 3390.
