 In journalctl shows some warnings that are the result of the fact that pulseaudio is started multiple at boot and user login. After analyzing I have identified the following locations which start pulseaudio:
+=== Systemd user service ===
-Systemd user service:
   $ systemctl --user is-enabled pulseaudio.socket
   enabled

   enabled
-XDG autostart
+=== XDG autostart ===
    ls /etc/xdg/autostart/*pulse*
    cat /etc/xdg/autostart/pulseaudio.desktop
-XFCE session startup
+=== XFCE session startup ===
    cat ~/.config/autostart/*pulse*
 ~/.config/autostart/pulseaudio.desktop. This file is created and set (hidden=true/false) by (un)checking XFCE -> Session and Startup -> PulseAudio at startup
+=== D-Bus Activation Mechanism ===
+D-Bus service file: There's a D-Bus service file that tells D-Bus how to start PulseAudio when something requests it:
+  /usr/share/dbus-1/services/pulseaudio.service
+  /usr/share/dbus-1/services/
+  /usr/share/dbus-1/system-services/
+  [D-Bus Service]
+   Name=org.pulseaudio.Server
+   Exec=/usr/bin/pulseaudio --start --log-target=syslog
+Automatic activation: When an application tries to connect to PulseAudio via D-Bus (requesting the org.pulseaudio.Server service), D-Bus automatically launches PulseAudio if it's not already running.
