As of September 11, 2026, Microsoft’s current PowerPoint support documentation still says that Insert > Screen Recording can capture the screen with related audio and that the Audio option is selected by default on the recording Control Dock. Microsoft does not currently flag a new, version-specific PowerPoint screen-recording audio outage in that support article. That means a silent recording is more useful to treat as a troubleshooting problem than as a confirmed new bug.
The fastest fix depends on what “audio not working” means in your case. If your own voice is missing, check the recording toggle, Windows microphone permission, and the selected input device. If audio from a browser, video, Teams call, or another application is missing, that is a different requirement: you need reliable system audio capture, and PowerPoint’s documented Screen Recording interface does not expose a separate system-audio source selector.
This guide focuses on PowerPoint desktop for Windows because Microsoft’s current Screen Recording instructions use the Windows recording workflow and Windows-key shortcuts.
| What you hear | Most useful first check |
|---|---|
| No sound at all in a new screen recording | Confirm the PowerPoint Audio control is enabled, then test the Windows recording input |
| Your voice is missing | Check microphone permission and the active Windows input device |
| Your voice records, but sound from another app does not | Treat this as a system-audio capture requirement, not simply a microphone failure |
| The microphone works in other apps but not after reopening PowerPoint | Restart PowerPoint, update Office, then repair Office if needed |
| The recording contains audio, but you cannot hear it inside the slide | Play the saved media separately to distinguish a capture problem from a playback-volume problem |
Open the slide where you want the recording, choose Insert > Screen Recording, select the recording area, and look at the Control Dock before pressing Record. Microsoft says PowerPoint automatically selects both Audio and Record Pointer by default. If Audio has been deselected, click it so it is active before beginning a new test.
Do not use an old silent clip to judge the new setting. Record a fresh 10-second sample after changing Audio. Say a few words at normal speaking volume, stop the recording, and play the newly inserted video.
If you see the Audio control and it is enabled but the new recording is still silent, move to Windows rather than repeatedly re-recording the same slide.
On Windows 11, go to Start > Settings > Privacy & security > Microphone. Microsoft’s current microphone-permission guidance says to turn on Microphone access and Let apps access your microphone. For traditional desktop programs, also scroll down and make sure Let desktop apps access your microphone is on.
A useful detail: Microsoft notes that desktop apps do not necessarily appear as individually switchable entries in the same way Microsoft Store apps do. Do not assume PowerPoint is blocked just because you cannot find a separate PowerPoint toggle. The relevant control for a classic desktop installation is the desktop-app microphone permission.
Microsoft documents these settings on its microphone permissions support page.
Go to Settings > System > Sound. Under Input, select the microphone you actually intend to use. This matters when a computer has several possible inputs: a laptop microphone array, USB headset, webcam microphone, Bluetooth headset, dock, or audio interface.
Open the selected microphone’s properties and use the Windows microphone test. Microsoft’s current troubleshooting instructions say to start the test, speak normally, stop it, and play the recorded sample. If Windows cannot record a clean sample, PowerPoint is not the right place to troubleshoot yet.
If the Windows test is silent:
Microsoft’s microphone troubleshooting page covers input selection, testing, volume, and driver checks.
After the PowerPoint Audio control, Windows permissions, and microphone input are correct, make a short test recording in a blank presentation. Keep it simple: one slide, a 10- to 20-second screen capture, and a few spoken words.
Play the clip inside PowerPoint. Then right-click the video frame and choose Save Media as, a workflow Microsoft documents on the same Screen Recording support page. Play the saved media file outside PowerPoint.
This separates two different failures:
Microphone audio and system audio are not the same thing. A microphone captures a physical input such as your voice. System audio means sound generated by the computer itself—for example, a browser video, app notification, media player, or another participant in an online call.
Microsoft’s current PowerPoint Screen Recording article documents one Audio control but does not document a separate picker for microphone versus system audio. Therefore, if your voice is present but the sound coming from another application is missing, repeatedly changing microphone permissions may not solve the real requirement.
For a Microsoft-supported recorder that explicitly documents system-audio sharing, Microsoft Clipchamp is clearer. Its current recording guidance lets you choose a screen and, where available, enable Share system audio. See Microsoft’s Clipchamp screen-recording instructions.
For presentation narration rather than general desktop capture, PowerPoint also has a separate Record presentation workflow that captures voice and slide timing. Microsoft documents it for PowerPoint for Microsoft 365 and supported perpetual versions, including Mac variants. See Record your presentation.
If the microphone passes the Windows test and PowerPoint still produces silent recordings, close other Office apps, reopen PowerPoint, and test again. Then install current Office updates.
For Microsoft 365 or Office on Windows, Microsoft’s current path is File > Account > Update Options > Update Now. If Update Now is not visible, your organization may manage Office updates centrally. Follow the official Office update instructions.
After updating, restart the computer and repeat the same blank-presentation test. Keeping the test identical helps you determine whether the update actually changed the result.
Repairing Microsoft 365 is a reasonable escalation when Windows records the microphone correctly, PowerPoint is up to date, and a new blank presentation is still silent. Microsoft supports both Quick Repair and Online Repair for Click-to-Run installations; Online Repair is the more comprehensive option.
On Windows 11, the general path is Settings > Apps > Installed apps, locate Microsoft 365 or Office, choose the menu for the product, and select Modify. Follow Microsoft’s Repair an Office application instructions for the exact options shown by your installation type.
Do not start with Online Repair if the microphone itself is failing in Windows. Repairing Office cannot fix a hardware mute switch, disconnected headset, or an input device that Windows cannot record.
If all microphone tests pass but PowerPoint remains silent after updating and repairing Office, the useful next step is to document your PowerPoint version, Windows version, recording device, and whether the saved media file is silent, then contact Microsoft Support or your organization’s Microsoft 365 administrator. Those details narrow the issue much faster than reporting only that “audio does not work.”
