Why can't you do it yourself?  This shouldn't be a very big stretch if 
you've already got it working for WASD.
Just use the joystick module of Pygame, and get the X axis movement, if 
it's positive and larger than a certain threshold, move to the right, 
and if it's negative and larger than the threshold, move left.  As for 
playing the sound, just use pygame.music() to stream it from disk, make 
a new folder called "commentary" where each item has the same name as 
the picture it's associated with.
So
root dir
    images
       foobar.jpg
       foobaz.bmp
    sounds
       foobar.mp3
       foobaz.mp3

then it's simple to just go "ok i'm currently at image "foobar.jpg".  I 
want to load a sound to play for it:
import os
soundfile = os.path.join("sounds", os.path.splitext(current_img)[0]+".mp3")
pygame.music.load(soundfile) # may not be correct function names
pygame.music.play()

So your main program will look like this (pseudocode warning!)

import os, pygame

init screen
#render wall

motion = 0 # how fast (in pixels) we shift the wall each frame.
speed = 2 # a multiplier for motion (i think joysticks report axis 
position as float from 0 to 1, this allows you to scroll faster.)
thresh = 0.5
while 1:
    pygame.clock.tick(60) #lock your framerate 
    #shift wall "motion" pixels in the x axis.
    refresh screen.
   
    for event in pygame.event.get():
        if event.type == JOYSTICKDOWN and event.button == BUTTONIWANT:
           #obviously for this to work must know current image. should 
not be hard to do.
            soundfile = os.path.join("sounds", 
os.path.splitext(current_img)[0]+".mp3")
            pygame.music.stop()
            pygame.music.load(soundfile) # may not be correct function names
            pygame.music.play()

       elif event.type == JOYSTICKMOTION:
           x = get_x_axis_of_joystick()
           if abs(x) > thresh:
               motion = x * speed
               pygame.music.stop() # unless you want commentary to keep 
playing while they scroll.
