A PowerPoint presentation can include sounds from various sources: narration and transition sounds, audio objects, videos and emphasized text. Animations can play sounds as well. You can remove all the sounds from your presentation one type of sound at a time; unfortunately, there is no option to remove all sounds from all slides automatically.
- You can undo the changes if you decide you want to keep some of the sounds. However, if you save and overwrite the original presentation, you may not be able to recover anything.
- PowerPoint automatically saves the presentation every 10 minutes, but it doesn't overwrite the original file.
- Sound objects and videos may be configured to play automatically when you run the presentation.
Remove Narration and Transition Sounds
Step 1: Removing Narration
Switch to the Slide Show tab, click the arrow below Record Slide Show, select Clear and then click Clear Narrations on All Slides to remove the narration from all slides simultaneously.
Video of the Day
To remove the narration from only the selected slide, click Clear Narration on Current Slide.
Step 2: Removing Transition Sounds
Select the slide that contains the transition sound, switch to the Transitions tab and then select (No Sound) from the Sound drop-down box in the Timing group.
You can't remove all transition sounds at once, so you have to manually remove them individually from each slide.
Audio Objects and Video Sounds
Step 1: Muting Videos
Select the slide that contains the video box, select the video and switch to the Playback tab. Click the Volume button in the Video Options group and select Mute from the menu.
- The Playback tab appears only after you select a video object.
- Even if the video starts playing automatically when you run the presentation, its volume is muted.
- To delete the video object, select it on the slide and press Delete.
- Prevent the video from playing automatically by selecting On Click, instead of Automatically, from the Start box in the Video Options group.
Step 2: Muting Audio Objects
Select the audio object on the slide and switch to the Playback tab that displays. Click the Volume button in the Audio Options group and select Mute from the menu.
- The audio object is muted even if it is configured to play automatically when you run the presentation.
- You can delete the object by selecting it and pressing Delete.
- To prevent the object from playing automatically, select On Click, instead of Automatically, from the Start box in the Audio Options group.
Removing Sounds From Emphasized Text
Although hyperlinks are usually enhanced with sounds in PowerPoint, any text can play a sound when you click or mouse over it. Enhanced text is highlighted and looks like a hyperlink.
Locate the enhanced text on the slide, select it, switch to the Insert tab and click the Action button in the Links group to open the Action Settings dialog.
Uncheck the Play sound boxes from both the Mouse Click and Mouse Over tabs to remove the mouse over and on-click sound effects. Click OK to apply the changes.
You can configure enhanced text to link to other slides or Web pages, or to run programs or macros.
Remove Sounds from Animations
Select the animated element, switch to the Animations tab and then click the small arrow in the bottom right corner of the Animation group to display the Appear dialog. Select (No Sound) from the Sound box and click OK.
You can't remove the sounds from all animations automatically; you must remove each one manually.
