How to Capture System Audio with PowerPoint Screen Recording
Question details
The user wants to record a specific portion of the screen along with its internal system audio, but PowerPoint's screen recording feature only captures the video.

- Product
- Microsoft PowerPoint
- Device & OS
- Windows
- Scenario
- Recording a screen area playing multimedia content, such as a YouTube video, to insert into a presentation slide.
- Observed behavior
- The screen recording tool captures the visual content successfully but fails to record the internal system sound output.
Before modifying your computer's sound configuration, ensure that your system's volume is unmuted, turned up, and that your audio device drivers are fully up to date.
Enable Stereo Mix in Windows Sound Settings
Route your computer's system audio through the microphone input by enabling the built-in Stereo Mix feature in Windows.
PowerPoint's native screen recording primarily listens to microphone input. By enabling Stereo Mix, you force Windows to treat your internal system audio as a microphone input, allowing PowerPoint to capture it.
Right-click the speaker icon in your Windows taskbar notification area and select 'Sounds' to open the Sound Control Panel.
Click on the 'Recording' tab at the top of the Sound window to view your available audio input devices.
Right-click anywhere in the empty white space of the device list and check the 'Show Disabled Devices' option.
Locate 'Stereo Mix' in the list. Right-click it and select 'Enable'. You may also need to right-click it again and set it as your 'Default Device' before starting your PowerPoint recording.

Use Dedicated Screen Recording Software
Bypass PowerPoint's limitations by using third-party screen recording software designed to capture system audio natively.

Frequently Asked Questions
Why is PowerPoint not recording my computer's audio?
PowerPoint's native screen recording tool is primarily designed to capture external microphone input (such as voiceovers) rather than internal system audio. Without enabling a hardware-level audio routing feature like Stereo Mix, the application simply ignores internal sounds.
Can I record screen audio on a Mac using PowerPoint?
The macOS version of PowerPoint does not natively support capturing internal system audio. Mac users typically need to use third-party virtual audio cables (like BlackHole) paired with QuickTime Player or specialized screen recording software to capture system sound.
How do I insert an externally recorded video into PowerPoint?
Once you have recorded your screen using an external application and saved the file (preferably as an MP4), open your presentation, navigate to the 'Insert' tab on the ribbon, click the 'Video' drop-down, and choose 'Video on My PC' or 'This Device' to insert it into your slide.
