I have had this problem twice during live customer presentations using
PowerPoint 2003 and 2007. I played two or three movie files (.mpg, .wmv)
within a PowerPoint presentation and then, when it came to the next movie
file, it played but had no audio. Very embarrassing.
I later discovered that the Windows volume control had somehow reduced
itself to zero - not muted, just zero.
The first incident was on a Dell with PPT 2003. The volume on that laptop
is controlled by a combination of two keys on the keyboard. After the
incident I used the keys and could see from the Dell on-screen display that
the volume bar was down to zero and then increased as I used the keyboard. It
had 'reset' itself to zero.
The second incident was with PPT 2007 and a different laptop, an IBM, which
has three manual buttons (instead of keys on the keyboard) to
increase/decrease/mute volume. The manual volume button was on and up to
maximum but the movie played in silence. I later discovered when I clicked
on the Windows speaker volume icon in the bottom right corner and selected
'open volume control', the grey slider-bar that appeared was right down to
zero.
After I told the person whose presentation had been ruined by the gaffe, he
came back to me and said, after thinking about it, that he had come across
the same thing before in our company's customer demonstration centre.
Any ideas? Is there something coded into one of the movies or movie file
types that says "reset volume to zero after playing"?
I also had a weird thing where movies would not play from one folder but
would play from another in the same directory. I have seen a post on that
about playing from a folder with a shorter file name.
Any suggestions on the volume thing?
Thanks!
