That's exactly my point. Since ESD support has been removed in fedora,
anyone trying to do gnome_sound_connection_get() will just get -1 back
anyway. Furthermore, the gnome_sound_play() docs say that the sound
may or may not play. So, why not just make it play a file with
libcanberra? If it fails, oh well. You're in exactly the same
situation you're in now. It seems pretty easy to me:
void gnome_sound_play(const char *filename)
{
#ifdef HAVE_LIBCANBERRA_GTK
ca_context_play(ca_gtk_context_get(), 0, CA_PROP_MEDIA_FILENAME,
filename, NULL);
#endif
}
I understand not wanting to write new apps to use gnome_sound_play
since it's deprecated. But it's existing API that can't be removed.
Why not have it work for apps that haven't been ported yet (or can't
be ported)?

Sure. I would not suggest that new apps use gnome_sound*.
