I think *probably* ALSA. IIRC, PulseAudio should resample streams to a 
rate the card can play, but it gets the information as to what streams 
the card can play from ALSA, I think. 'pulseaudio -k; pulseaudio -
vvvvv' output might have some interesting nuggets in it (you may need 
to create a ~/.pulse/client.conf with 'autospawn = no' as the content 
to disable auto-respawning; remember to delete it afterwards).

Does it work if you play, say, a 48KHz stream in mplayer and then 
start playing a 44.1KHz stream in Totem or Rhythmbox *at the same 
time*? That should force resampling.
