You do not have D-Bus support enabled. It is strongly recommended
that you enable D-Bus support if your platform supports it.
Many parts of PulseAudio use D-Bus, from ConsoleKit interaction
to the Device Reservation Protocol to speak to JACK, Bluetooth
support and even a native control protocol for communicating and
controling the PulseAudio daemon itself.

the primary method used to detect hardware audio devices (on Linux)
and is thus a critical part of PulseAudio on that platform.
