Hmm, is it then impossible to move event sounds? Doesn't seem like a
good way to do it.

canberra-gtk-play doesn't seem to work here, errors out with:-
Failed to play sound: Sound disabled
I've never used it before, and I believe libcanberra on my system may
not even have pulseaudio support compiled in, hence my preference for
paplay (I don't use any gnome event sounds).
