no sound with pps file

[Shinnen]

Hi,
My wife and I both have the same OS, 98se. When I play a pps file, that
a friend sent to us, I get sound. When she plays the same file, which I
copied to her system, she gets NO sound. We both get the slide show. We
both have the same versions of Power point, SR-2 I think.
I can play a .wav file on her machine and get sound, so I know the
hardware's working.
I've read all the advice elsewhere re link in powerpoint, but I can't
really make head nor tails of it.
Thanks,
John

Hi Steve,
Thanks for the link. I think I only have the one file, but ????
If there is another, sound, file on my system which is linked to my pps
file, how would I find it?
