All of this looks fine.

Yes you are right, the Audigy native soundfont support is absolutely
nothing to do with DSSI. A couple more things you could try:

1. Install the dssi-devel package if you don't already have it, and try
running trivial_synth.so and less_trivial_synth.so. They are both
extremely simple, so it might be worth seeing what they do.

2. I would be interested to see if my DSSI host for PD works on your
system. You can get it from http://www.puredata.org/Members/jb. It is
still under development, and I would only bother if you already know a
little PD. 

Incidentally does LADSPA work on your system?
