Hi Roger,
You don't state your version of PowerPoint, but in v.2002 this works:
TO PLAY SOUND THROUGHOUT: Click thumbnail #1 | Click SLIDESHOW | CUSTOM
ANIMATION | if necessary click on name of sound file. Click the down-arrow
to the right of the name | EFFECT OPTIONS | PLAY SOUND | STOP PLAYING |
select AFTER and type 999 for the number of slides | TIMING | REPEAT | type
1000 | OK.
TO LOOP THE SOUND: On slide #1, right-click the sound icon | In the
drop-down menu click EDIT SOUND OBJECT (SPEAKER ICON) | Check "Loop until
stopped" | OK.
TO LOOP THE SLIDES: Click SLIDESHOW | SET UP SHOW | SHOW OPTIONS | Check
"Loop continuously until 'Esc' " | OK.
Good Luck.
