# First, you should install XRDP and X11 Desktop Environment first.

# Step 1 - Install Some PreReqs
sudo apt-get install git libpulse-dev autoconf m4 intltool build-essential dpkg-dev libtool libsndfile1-dev libspeexdsp-dev libudev-dev -y

# Enable source repo
sudo cp /etc/apt/sources.list /etc/apt/sources.list~
sudo sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
sudo apt-get update

sudo apt build-dep pulseaudio -y

#  Download pulseaudio source in /tmp directory - Do not forget to enable source repositories
cd /tmp
apt source pulseaudio

cd /tmp/pulseaudio-$pulsever
./configure --without-caps
