music playback problems only on first slide

[grannash]

I have a file that I haven't modified since last year but suddenly the music
on it is doing strange things. When I start the presentation, the music
starts as it should, but then it starts again a second time, while the first
time is still playing, so you can hear the music playing twice, but out of
synch about 5-10 seconds. Once I advance to the second or subsequent slide,
this goes away completely. I thought it was some sort of problem with just
too many resources being used causing the problem, so I waited for things to
'settle', but they don't. You can view the first slide for 5 seconds or 50
seconds and you always get the file playing twice out of sync and then it
plays properly the instant you go to the next slide.

How can this happen when the file hasn't been modified since October 2006
and it worked just fine yesterday and the day before that. I've been having
many troubles with music and slide advancing and deliberately made a copy of
this file to work out the problems fully before touching this file. But now
it seems this file is screwy and I haven't even done anything to it. I'm so
frustrated with this whole thing!

A couple of things to check:

Make sure there isn't a second copy of the music on another slide.
Try HTML round tripping to repair corruption:

How can I tell if there is a second copy? On the slide sorter view, there is
some sort of star below the first slide - is that significant?

Also meant to say - I've tried to do this round tripping, using the link
you've given, but it says near the beginning that a box will pop up right
after you click save as web page, but it never does for me, it just goes
ahead and saves without allowing me to specify anything.

That indicates a slide transition is applied to the slide.

Do a File, Save As, and select Web Page (*.htm, *.html) as the Save as type:

It will create a folder with all your images and sound files. See:
http://pptfaq.com/FAQ00241.htm for an explanation about the files and folders.

Check the support file folders for the sound files. If you have more than
one, that's the culprit. I would delete all the sound files, save the
presentation back to a new PPT file and add the single desired sound file to
that presentation.
