X11RDP – How to Install and Configure X11RDP

As there is a proprietary implementation of fransferring of audio via a RDP connection on Windows (Audio Output Virtual Channel Extension) but this feature is not available from X11RDP server (or VNC as a sidenote), where only basic remote protocols such as screen, keyboard, or mouse are present.

To be able to get the sound output of the server sent to a client we therefore need an additional protocol. Provided we had installed pulseaudio on our Wyse OS this can be done by using pulseaudio's inbuilt network features. These are all nicely documented and listed here:

Pulse Audio Network Setup

The transfer methods may be set up by command line, or with a GUI using paprefs .

X11rdp tries to improve on Xvnc by forwarding X11 draw commands as RDP draw commands instead of simply wrapping a vnc bitmap stream in RDP.

Draw commands are more bandwidth efficient as it can be vector based instead of just a raw video feed. X11rdp vs Xvnc for the desktop is similar to MIDI vs WAV for music. MIDI describes which notes are played while WAV simply encodes the resulting sound.
