How to Record a PowerPoint Slideshow With System Audio Captured

You need to record a PowerPoint slideshow that includes both your voice and the audio from your computer, such as a video clip or sound effects playing during the presentation. By default, PowerPoint’s built-in screen recording captures microphone input but not system audio, leaving your embedded media silent. This article explains how to configure PowerPoint to record system audio alongside your narration using a simple setting change. You will also learn an alternative method using a third-party tool if your version of PowerPoint does not support system audio capture.

How PowerPoint Handles Audio Recording During a Slideshow

PowerPoint’s native recording feature, found under Slide Show > Record Slide Show, is designed primarily for creating narrated presentations. In older versions and PowerPoint for Microsoft 365 up to a certain update, the tool only captures microphone input. This means any audio played from within the slideshow — such as an embedded YouTube video, a sound effect, or a system notification — is not included in the final recording.

Microsoft added a Record System Audio option starting in version 2205 of PowerPoint for Microsoft 365. This setting is located on the Recording tab after you begin a recording session. When enabled, it captures all audio output from your system, including the sound from embedded media, browser windows, and other applications. The feature works only in the desktop version of PowerPoint for Windows. It is not available in PowerPoint for Mac or PowerPoint for the web.

Before you start, ensure your system audio drivers are up to date and that no other application is exclusively using the audio output device. If you use Bluetooth headphones or speakers, check that they are set as the default playback device in Windows Sound settings. PowerPoint records whatever audio is routed through the default playback device.

Steps to Record a PowerPoint Slideshow With System Audio

Follow these steps to enable system audio capture and record your slideshow. The process assumes you have PowerPoint for Microsoft 365 version 2205 or later.

1. Open your presentation and check audio devices
   Open the PowerPoint file you want to record. Click Slide Show > Record Slide Show and select either Record from Beginning or Record from Current Slide. The recording interface opens. Before speaking, click the gear icon (Settings) in the top right corner. Under Audio Device, confirm your microphone is selected. Under Audio Output, confirm your speakers or headphones are set. Close the settings.
2. Enable the Record System Audio option
   On the Recording tab in the top ribbon, locate the Audio group. You will see a checkbox labeled Record System Audio. Select this checkbox. A small speaker icon appears next to the timer, confirming system audio is being captured. If you do not see this checkbox, your version of PowerPoint does not support the feature. Skip to the alternative method below.
3. Start the recording
   Click the red Record button on the Recording tab or press Windows logo key + Shift + R. PowerPoint begins capturing your slideshow. Advance slides normally using your mouse, keyboard arrow keys, or a clicker. Play any embedded media such as videos or audio files. System audio from those media files will be recorded.
4. Stop the recording
   When you finish presenting, click the Stop button in the top left corner of the screen or press Windows logo key + Shift + Q. PowerPoint automatically saves the recording as a new slide in your presentation. Each recorded slide shows a speaker icon in the bottom right corner.
5. Export the recording as a video file
   With the recording complete, go to File > Export > Create a Video. Choose a resolution and timing option. Click Create Video, name the file, and select a save location. The exported MP4 file includes both your narration and all system audio captured during the session.

When PowerPoint’s Built-in System Audio Recording Fails

PowerPoint version 2204 or earlier does not show the Record System Audio checkbox

If you use an older version of PowerPoint, the Record System Audio option is not available. You can update PowerPoint to the latest version by going to File > Account > Update Options > Update Now. If your organization restricts updates, or if you prefer not to update, use a third-party screen recorder such as OBS Studio. OBS captures both microphone and system audio independently of PowerPoint. Set up OBS to capture the PowerPoint window and configure audio sources in OBS settings.

System audio is recorded but sounds distorted or out of sync

Distortion or sync issues usually stem from high CPU usage during recording. Close all unnecessary applications before recording. Reduce the video resolution in PowerPoint’s export settings to 1080p or 720p. If the problem persists, disable hardware graphics acceleration in File > Options > Advanced > Display > Disable hardware graphics acceleration. Restart PowerPoint and try recording again.

Embedded video audio is not captured even with Record System Audio enabled

This can happen if the embedded video uses a codec that PowerPoint cannot play natively. Convert the video to MP4 format with H.264 encoding using a free tool like HandBrake before inserting it into your slide. Also verify that the video is set to play automatically or on click. Right-click the video, select Playback, and choose Automatically or When Clicked On.

PowerPoint Built-in Recording vs OBS Studio for System Audio Capture

Item	PowerPoint Built-in Recording	OBS Studio
System audio capture	Yes, with Record System Audio checkbox (version 2205+)	Yes, via Audio Output Capture source
Microphone capture	Yes	Yes
Separate audio tracks	No, all audio mixed into one track	Yes, up to 6 independent audio tracks
Export format	MP4 or WMV	MP4, MKV, FLV, MOV, and more
Editing after recording	Limited to trimming in PowerPoint	Full timeline editing in OBS or external video editor

You can now record a PowerPoint slideshow with system audio captured using the built-in Record System Audio feature or OBS Studio. After recording, export your presentation as a video file to share with colleagues or upload to a learning platform. For advanced control over audio tracks, use OBS Studio and edit the separate microphone and system audio streams in a video editor like DaVinci Resolve.
