Indeed, but both GStreamer and VLC can run on top of PulseAudio. They can also (of course) run on top of ALSA, but then you loose all the nice things PA provides. At least with GStreamer (directly on top of ALSA) you don't get per-application volume, seamlessly changing sound cards or easy integration with USB soundcards and bluetooth headsets; I don't use VLC, but I believe is the same. ALSA is the bottom of the stack, PulseAudio goes above it, and then you can have GStreamer, VLC, ffmpeg, Xine-lib or whatever, which are the high-level libraries. All of the high-level libraries cantalk to ALSA directly; but none of them provide by themselves the features that PulseAudio has.
