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

sudo apt-get install dpkg-dev
E: You must put some 'source' URIs in your sources.list
try running the following command first:
non root
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
non root
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

To test sound/microphone redirection
--------------------------------------
o install gnome sound recorder or your favorite sound recorder
o mplayer -ao pulse <audio file>
o sudo apt-get install pavucontrol
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
log-level = notice
o pulseaudio --kill
