Reply To: MP3 audio as a background music in PDF

I have finally found some solution – i must export the interactive PDF with the MP3 inserted on the first page. Then I open it in Acrobat, here rightclick on the music element, and in the dialog choose “open in floating window” (and specify the width + height of this window, which can be also 1×1 pixel, if you want it to be very small). I use 301×34 pixels – it creates a fine player icon over my PDF.
