I've been editing some mp3's in my sound editor, then re-inserting them into
my pps slide. Yes, I delete the old one first. (Note that I use the same
file name as the original. This doesn't appear important but bear with me.)

On two slides I was astounded that the last several seconds of each sound
file were omitted. The first one played 16 of 22 seconds. The next played 46
of 58 seconds.

While I still have hair left I think I've sourced the problem. On the first
one I clicked on Custom Animation, Right click on the sound clip, Timing,
Sound Setting. I then saw under Information "Total playing time: 00:16"
followed by the file path and name.

It looks as if the total playing time is now hard wired with a playing time
that is obsolete since the new file is 22 seconds long.

Have I done something wrong? I suppose a workaround would be to rename the
newly edited file and insert that. While I haven't tried that yet I wanted
to report this here first at the chance that I truly have done something
wrong.
