I think a small wrapper aroun gstreamer could be made that would support
those system level hooks.

in pseudocode

void gnome_play_sound (const char *event_name)
{
char *sample_name, *event_desc;

sample_name = get_sample_from_event (event_name);
event_desc = gst_description_from_event (event_name);

play_sample_on_gstreamer_pipeline (sample_name);
emit_system_level_hooks (event_name, event_desc);
}

or something like that.

The GStreamer pipeline would be incredibly simple
filesrc ! decoder ! audiosink
and could be kept around while nothing is happening so that it doesn't
need to be rebuilt.

Whether the GStreamer guys want to be this low in the gnome dependancy
chain yet is another/different matter.
