Document Classes ⇒ beamer | Sound persistent over Frames

[havarpan]

Hi,

it is written in the beamer documentation (version 3.20, section 14.2, page 141) that "A sound playback can persist after the current page is closed (though it need not)." I haven't found out how to make this work. I'm using Adobe Reader 10.1.3 on Mac OS X 10.7.4. Here's a sample code:

Code: Select all

\sound[autostart]{}{sound.wav}
\frame{
\frametitle{Frame 1}
\includegraphics{picture1.eps}
}
\frame{
\frametitle{Frame 2}
\includegraphics{picture2.eps}
}

I would like to switch from frame 1 to frame 2 while the sound is playing. Currently the sound either stops (on the first try) or I have to wait until the sound has played before being able to switch frames (when coming back from frame 2 to frame 1). Putting the \sound command inside frame 1 makes no difference. Any experiences, perhaps on other systems? Greetings,

Harri
