How to Set a Background Music Track Across All Slides in PowerPoint

When you add a song to a PowerPoint presentation, the music stops playing as soon as you move to the next slide by default. This creates a disjointed experience for your audience during a slideshow. The cause is that PowerPoint treats each audio file as a per-slide object unless you change its playback settings. This article shows you how to set a single background music track to play continuously across all slides in PowerPoint for Windows.

How PowerPoint Handles Audio Across Slides

PowerPoint does not automatically play a single audio file across multiple slides. Each audio clip you insert is linked to the specific slide where you placed it. When you advance to the next slide, PowerPoint stops all audio from the previous slide unless you change the Playback options. The key setting is Play Across Slides, which tells PowerPoint to continue the audio track even after the slide changes. You must also decide whether the track should restart after it ends using the Loop until Stopped option. No additional software or add-ins are required for this feature. It works in PowerPoint 2016, 2019, 2021, and Microsoft 365 for Windows.

Steps to Insert and Configure Background Music for All Slides

Follow these steps to add one music file and make it play across your entire presentation.

1. Open your presentation and select the first slide
   Go to the slide where you want the music to start. Usually this is the first slide in the deck. The audio object will be visible on this slide only.
2. Insert the audio file
   On the ribbon, click the Insert tab. In the Media group, click Audio and select Audio on My PC. Navigate to your music file, select it, and click Insert. A speaker icon and a playback bar appear on the slide.
3. Open the Playback tab
   Click the speaker icon on the slide to select it. The ribbon shows a new tab called Audio Format and another called Playback. Click the Playback tab.
4. Enable Play Across Slides
   In the Audio Options group, click the Start drop-down list and select Play across slides. This is the main setting that keeps the music playing as you move through the presentation.
5. Enable Loop until Stopped (optional)
   Still in the Audio Options group, check the box labeled Loop until Stopped. This makes the track repeat from the beginning after it ends. Use this if your presentation is longer than the song duration.
6. Hide the audio icon during the slideshow
   On the same Playback tab, check the box labeled Hide During Show. This removes the speaker icon from view so your audience does not see it. The music still plays.
7. Test the playback
   Press F5 to start the slideshow from the beginning. Listen for the music to continue without interruption as you click through each slide. Press Escape to exit.

If the Music Stops or Behaves Incorrectly After the Setup

Even after you apply the settings above, the music may stop on certain slides or fail to loop. The most common cause is a conflicting animation trigger or a second audio file on a later slide. PowerPoint can only play one audio stream at a time. If you inserted another audio clip on slide 5, for example, PowerPoint stops the background music when it reaches that slide and plays the new clip instead.

Background music stops on a specific slide

Check every slide for additional audio files. Go to each slide and look for a speaker icon. If you find one, select it and press Delete. Then return to the Playback tab on your original audio file and confirm that Play across slides is still selected. If you need sound effects on individual slides, use the same audio file and trim it in PowerPoint instead of inserting a separate file.

Music plays only on the first slide

This usually means the Start option is set to Automatically instead of Play across slides. Click the speaker icon on the first slide, go to the Playback tab, and change the Start drop-down to Play across slides. Also verify that no animation triggers are set on the audio icon. Select the icon, click the Animations tab, and click None if an animation is listed.

Music does not loop

Open the Playback tab and check the Loop until Stopped box. If the box is already checked, the file format may not support looping. Convert the audio file to MP3 or M4A using a free converter and re-insert it. PowerPoint supports looping for MP3, WAV, and M4A files reliably.

Playback Options for Background Music: Slide-by-Slide vs Continuous

Item	Play Across Slides	Play on Click / Automatically
Music behavior	Plays continuously through all slides	Plays only on the slide where the audio icon sits
Loop support	Works with Loop until Stopped	Loop plays on the same slide only
Icon visibility	Can be hidden with Hide During Show	Icon remains visible unless hidden
Best use case	Background music for entire presentation	Sound effects or narration on one slide

After you apply the Play across slides setting and hide the icon, your background music will play from the first slide through the last slide without interruption. If you need the music to restart automatically, enable Loop until Stopped. For presentations longer than five minutes, consider trimming the audio file in PowerPoint to match the presentation duration using the Trim Audio tool on the Playback tab. This prevents the track from ending abruptly if you do not enable looping.
