How can i stream audio from ubuntu 12.04 server to wyse s10 terminals using X11RDP?!
There is no way to do it since you must install pulse audio package on the client which is impossible to be done on the Wyse s10 terminal so no way to stream audio from an Ubuntu server to a Wyse s10 terminal
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:
The transfer methods may be set up by command line, or with a GUI using paprefs .
