We answer this question based on usage scenarios (the software operation is based on office216).

1. I want the background music to play automatically

The steps are as follows:

1. Select the slide to start the music;

2. click "insert"-"audio" and select the audio to be inserted

3. in the pop-up audio tool tab, select "start-automatic" to automatically play the background music during the current slide show. If you need the background music to play all the time, you need to check "Play across slides".

similarly, if you need background music to be played only on the current slide, just uncheck "Play across slides".

2. I want the background music to play all the time

Solution 1:

Click the inserted audio object and check "Loop until it stops" in the Play tab, so that the background music can be played all the time until we quit the slide show.

Solution 2:

Control the slide show playback speed or insert an audio file with a long enough playback time [manually funny ]

Third, I want the background music to be played between designated pages

The steps are as follows:

1. Insert an audio file in the PPT of the first page of the designated page

2. Click the inserted audio object

3. Check "Cross".

for example, if I want to play background music on pages 3-6, I will insert audio on page 3 and select "After slide 4" to stop playing.

note: the "stop playing" function will also count the hidden slide pages.

The above is the main content of this answer. office216 can also edit the inserted audio files twice, and more functions are waiting for you to discover.
