[Fluxus] Audio Problems

[s s]

I'm having issues getting Fluxus to work with audio. I have tried running

(define (animate)
  (start-audio "qjackctl:capture_1" 1024 44100)
  (colour (vector 0 1 (gh 3)))
  (draw-cube))
(every-frame (animate))

And it doesn't seem to be doing anything.

I have tried running "/usr/bin/jackd -R -P80 -dalsa -dhw:0 -r44100
-p1024 -S -Xseq" in the command prompt and nothing happened when I
tried to play music. Any idea what I'm doing wrong?

I'm using Ubuntu Hardy Heron, and installed using the package here:
