I have had this error for a while now. Sometimes the terminal sessions don't seem to work after using the "shut down"-button.
I find it odd too, that pulseaudio doesn't seem to shut down successfully.
syslog shortly after failed shut down (and login again, because terminal session didn't work this time):
Sep 21 00:15:37 PC-Kristian-Linux pulseaudio[6999]: [pulseaudio] pid.c: Daemon already running.
None of the suggestions above worked for me. (still typing "sudo init 0")
