Pulse audio notes.
to see what version of PA is on your machine
pulseaudio --version
To build xrdp pulse sink,
get the pulse source that most closely matches your version on
your machine. Get the source from
http://freedesktop.org/software/pulseaudio/releases/
run ./configure after extracting. I don't think you need to build it.
edit Makefile to point to your pulse source directory.
PA always respawning
To stop its respawning habit, open /etc/pulse/client.conf, change
autospawn = yes to autospawn = no, and set daemon-binary to /bin/true.
Make sure these lines are uncommented, like this:
autospawn = no
daemon-binary = /bin/true
