    NOTE: If you get an error message that goes something like this: 

    E: You must put some 'source' URIs in your sources.list

    try running the following command first:

    apt-get source pulseaudio

o run these commands in your home directory

    cd
    sudo apt-get install dpkg-dev
    apt-get source pulseaudio
    sudo apt-get build-dep pulseaudio

    cd pulseaudio-1.1
    dpkg-buildpackage -rfakeroot -uc -b

o edit Makefile and point PULSE_DIR to ~/pulseaudio<version> dir

o run make; the outputs will be 
  module-xrdp-sink.so
  module-xrdp-source.so

o sudo cp module-xrdp-sink.so   /usr/lib/pulse-<version>/modules
  sudo cp module-xrdp-source.so /usr/lib/pulse-<version>/modules
  note: on a 64bit machine use lib64 instead of lib

o cd /etc/pulse

o sudo mv default.pa default.pa.orig

o sudo vi default.pa and add the following lines to it

.nofail
.fail
load-module module-augment-properties
#load-module module-alsa-sink device=hw:0
#load-module module-alsa-source device=hw:0
#load-module module-pipe-sink
#load-module module-pipe-source
#load-module module-null-sink
load-module module-xrdp-sink
load-module module-xrdp-source
load-module module-native-protocol-unix
#load-module module-udev-detect tsched=0

o sudo apt-get install pavucontrol

o pulseaudio --kill

o mplayer -ao pulse <audio file>

o in another window run pavucontrol and you should see xrdp-sink in use

o to enable pulseaudio log
    o edit /etc/pulse/daemon.conf and set
      log-target = syslog
