With the default /etc/pulse/default.pa I have no sound at login. I can only get sound by loading the jack modules and running Jack. System Settings -> Multimedia -> Phonon -> Device Preference only shows the dummy output and the Jack sink, which cries out to me that there's still something wrong with my PulseAudio configuration.
