The init_live script appears to have some naming issues FWIW.

I keep getting "not enough tram" or similar when I try to load FX. 
Can you clue me on what you did?

AFAICT, you can just drop in the blocks you need and connect 'em up
(context menus for the connections are available if the cursor is hovering 
over the line - took me a while to find that), then the controls show up in 
the mixer. It crashes kmix when things change but IIRC you get the AC97 
section + whatever you define in alsamixer (or aumix, what have you)
IOW you can apparently define the whole signal path
