+Launching pulseaudio
+```
+echo "autospawn = no" > ~/.config/pulse/client.conf
+pulseaudio --kill
+rm -rf ~/.config/pulse/
+docker-compose up -d
+```
+
+If you wish your host system to use your docker pulseaudio server, e.g.
+accepting Fn volume Up/Down and On/Off keys, issue the following command
+```
+xprop -root -f PULSE_SERVER 8s -set PULSE_SERVER "tcp:localhost:4713"
+```
+
+To remove pulseaudio properties from environment variables
+```
+pax11publish -e
+```
+
+To test whether pulseaudio is working
+```
+PULSE_SERVER="tcp:localhost:4713" pactl list
+PULSE_SERVER="tcp:localhost:4713" alsamixer
+PULSE_SERVER="tcp:localhost:4713" mplayer some.avi
+```
