Why does my screen recording have no sound in Windows 11? This usually happens when Windows switches your input device, microphone access is blocked, or your recorder is set to the wrong audio source.
In Pakistan, this becomes a bigger problem during Zoom classes, office demos, and YouTube tutorials because you often notice the missing audio only after the recording is finished.
The risky move is installing random “audio fix” apps or cracked recorders that add unsafe drivers or mess up Windows audio settings.
This 2026 guide shows fast checks that fix the issue first, and helps you avoid repeating a full lecture or tutorial again.
Most “no sound” screen recordings come from three places: Windows sound settings, microphone privacy permissions, or the recorder’s selected audio source. Fix those first, then test with a short 10–15 second recording before doing a full session.
Understanding Screen Recorder No Sound in Windows 11

No sound during screen recording can feel confusing because everything looks fine on screen. But in many cases, audio is blocked or redirected quietly in the background.
Windows 11 updates, Bluetooth earphones, webcam microphones, and switching between speakers and headphones can change your default input device without warning. When that happens, your recorder may capture video only, with no voice or system sound.
Knowing the usual causes makes fixing the problem faster.
Common Causes of Audio Issues
Here are the most common reasons screen recording audio fails in Windows 11:
- Windows selects the wrong microphone or input device
- The recorder app is muted in Volume Mixer
- Microphone access is blocked in privacy settings
- The recorder is set to record mic audio instead of system sound, or vice versa
Impact on User Experience
Missing audio ruins recorded lectures, training videos, and client demos. For students, teachers, freelancers, and office teams in Pakistan, it often means wasted time and stress.
Fixing audio properly helps you record clear lessons, clean tutorials, and professional demos.
Troubleshooting Steps for Screen Recorder No Sound in Windows 11
Follow these steps in order. They fix most cases without advanced tools.

Windows Sound Settings Check
Start with Windows sound settings. Right-click the speaker icon in the taskbar and open Sound settings.
Make sure the correct output device is selected and nothing is muted. Also confirm the system volume is not too low. After any change, do a short test recording so you do not lose a full lecture again.
Check Volume Mixer for the Recorder App
Sometimes Windows mutes only one app, not the whole PC. This is common after updates or when switching devices.
Open Volume Mixer and find your screen recorder and browser. Make sure they are not muted and the volume slider is not at zero. Then test again with a 10–15 second recording.
Adjust Microphone Permissions
Microphone access is required to record your voice. In Windows 11, apps can be blocked even if the microphone works in other programs.
Go to Settings > Privacy & security > Microphone. Turn on microphone access and allow your recorder to use it. Close the recorder, reopen it, and test again.

Set the Correct Default Input Device
Windows can auto-switch your microphone when you connect a headset, webcam, or Bluetooth earbuds. Your recorder may still be listening to the old device.
Go to Settings > System > Sound > Input and select the microphone you actually want. Speak and check the input level bar moves. Then set the same microphone inside your recorder app.
Select the Right Audio Source in the Recorder
Inside your screen recorder, confirm what you want to record:
If you need system sound, enable system audio. If you need your voice, select the correct microphone. If you are making tutorials, many users need both on.
Always check this before you press Record.
Conclusion
Why does my screen recording have no sound in Windows 11? In most cases, Windows picked the wrong mic, the recorder is muted in Volume Mixer, or microphone permissions are blocked. Fix those first, then test with a short recording.
