Name it A_sound. 5. In this layer, put key frames at the beginning and approximate ending of the audio file.

Highlight Frame 1, and drag the avi file onto the Stage or into the frame. The audio pattern will show up as a long waveform in the A_sound layer. 7. In the Property Inspector, note that when the Asound layer is selected, the name of the audio file appears in the Sound box, and "stream" is selected in the Sync box. For sounds that play throughout a Flash movie that will appear on the Web, select stream.
