pulseaudio crash

[liyuming1978]

1.  PulseAudio daemon is not started when the system boot up. So how to make PulseAudio daemon run as a system service so that it can automatically start when the system boot up? 
   

2.  When I manually launch PulseAudio, the following message are shown: 
   

   W: [pulseaudio] main.c: This program is note intended to be run as root (unless –suystem is specified)
   W: [pulseaudio] Server-lookup.c: Unable to contact D-Bus: org.freedesktop.DBus.Error.NotSupported: Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead
   W: [pulseaudio] main.c: Unable to contact D-Bus: org.freedesktop.DBus.Error.NotSupported: Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead

Does this mean something wrong when I manually launch PulseAudio daemon? How to fix it?
3. When I manually launch PulseAudio, the daemon will stop after a short time. Why?
4. When my phone is connected with Ostro device by Bluetooth, playing music on the phone causes pulseaudio daemon crash and the following message is shown:
[152325.073335]pulseaudio[1554]: segfault at 6e1ad0 ip 00000000006e1ad0 sp 00007ffcf83de9e8 error

In general it's also good to check the PACKAGECONFIG settings are tuned for your needs (e.g., x11 not needed). The recipe has the default ones and no ostro-os specific tuning is done.
