Apparently pulseaudio is unable to get D-Bus services, due to a dependency of the latter on X. So you need either to satisfy/finesse this dependency of D-Bus, or disable/remove pulseaudio. I've read but not tested apulse, a library that purports to presents a pulse audio API to applications such as skype that require them, relaying the audio to ALSA. If you have a choice, perhaps you can select linux audio applications that target ALSA, or if you are involved in music production, JACK. A few have reported good results with the latest OSS audio drivers (an alternative to ALSA), however these are definitely in the minority.
