No sound

[RTT]

Hi Gustavo, thanks for posting all this info

So what Adobe is saying is that Adobe Reader uses his built-in player, so if I set Multimedia Trust to allow always only Adobe Flash Player (Three others to never), it should work.

Not exactly what I read in these lines. What they say is that If the PDF contains legacy rich media format (indeed the format used by the PDFrizador to make the PDF's compatible also with older than the Reader 9 version), it will be played always by an external player. Only when the rich media format is Flash, the embedded Flash Player will be used.
So, you problem remains connected to some problem with the external player Acrobat is trying to use.

Hi RTT:
So as I said in an earlier post, and also as you said in your last post, it's necessary to have installed and external`player. So I'd installed WMP and Presentations with .mp3 sounds are playing fine.
Still can't play with .wma sounds, but is a problem of my PC or a Win XP - Adobe Reader X issue, since I can play them in my notebook with Win 7.
But I never use .wma files so I'm goimg to use only .mp3 sounds.

Thanks for all again and for your soft.
Best Regards
Gustavo
