Let multiple objects play together in PowerPoint

When I was making English courseware in PowerPoint, I added a total of three multimedia objects in a slide with super Jie Ba interception video Stream (MPV), English commentary (MP3) and background sound (MP3). When you join, you choose to have the slide show play automatically. The results of a debug run are not satisfactory. Opens the Custom Animation dialog box, which starts with 0 seconds after the previous event (Figure 1).

What causes three of multimedia objects not to be synchronized? Finally, in the author's efforts, the film, commentary, sound effects three multimedia objects "obediently" as I thought in the slide show at the same time play.

The method is simple: Open the "Multimedia Settings" tab of "Custom Animation", and change the setting of Figure 2 to the setting on Figure 3. Interested friends hurry to try it.
