First,? Find page templates

First, we need to open a PPT file containing background music. Click View on the menu bar, and then click Slide Master. In slide master mode, we can see all the page templates.

Second,? Select sound options

Then, find the music icon, click the right mouse button and select "Sound Options". In the pop-up window, you can uncheck "Loop until it stops" so that the background music will only be played once.

Third,? Click the Delete option.

If you want to completely remove the background music, you can continue to right-click the music icon and select "Delete", and the background music will be permanently removed. Of course, you can also choose to change the background music and add your favorite music files.
