Sound in the Player

Some of the content viewable in the Player may contain sound. The behavior of sound in the Player is described in this section.

Before you can hear sound through the Player, you must:

• Set the Play Audio preference to All Available sound or Keyboard and Mouse Clicks.
• Install Adobe Flash 9.0 or later.

  Note: If Flash is not installed, you can view the content without sound by disabling Play Audio in the Player Preferences.

Sound on Conceptual Content

When sound is attached to conceptual content (i.e., information displayed in the Concept pane without running one of the Playback modes), the Play Sound /Pause Sound , Stop Sound icons and a progress bar display below the Playback buttons so you can control the sound playback. By default, sound plays automatically when you select an item in the outline. If you press Stop Sound, sound playback toggles off so if you select another item in the outline the sound will not automatically play. You can toggle automatic sound playback back on by pressing Play Sound again.

If you re-launch the Player, the sound playback mode is remembered from the last usage.

Sound on Playback Modes

Sound playback is available during the See It!, Try It! and Do It! playback modes. Sound in these modes plays automatically when the topic displays. Pausing the simulation using the Action link that appears in the bubble also pauses the sound.

Sound is disabled during Know It? mode because this mode is designed to test the user's knowledge about the content.
