iPhone Screen Recording No Sound? Fix It
If your iPhone screen recording has no sound, the most common cause is that the microphone is not enabled—by default, screen recordings capture only audio from the device itself, not your voice or surrounding sounds. To fix this, start a screen recording, then long-press the record button and tap the microphone icon to turn it on. This article explains why the issue happens, how to fix it, and answers related questions about recording sound on your iPhone.
Why Your Screen Recording Has No Sound
Apple’s screen recording feature has two distinct audio modes. The default mode records only the audio that plays through your iPhone’s speakers—like music, video dialogue, or game sounds. It does not capture your voice or any ambient noise. To record your voice, you must explicitly enable the microphone. This design prevents accidental voice recording and keeps the file size smaller. When users expect their voice to be included without turning on the mic, they get a silent video.
Another common reason for no sound is that the audio source itself is muted. For example, if you’re recording a video call or a streaming app, the app’s volume might be at zero, or the phone’s silent switch could be on. The screen recording captures whatever audio the device is outputting, so if the volume is down, the recording will be silent.
How to Enable Microphone for Screen Recording
Here are the exact steps to turn on the microphone for a screen recording on iOS 17 and later:
- Open the Control Center (swipe down from the top-right corner on iPhones with Face ID, or swipe up from the bottom on older models with a Home button).
- Long-press the screen recording button (a circle inside a circle).
- In the menu that appears, tap the microphone icon at the bottom. When it’s on, the icon turns red and shows “Mic On.�
- Tap Start Recording (or just tap anywhere outside the menu).
- When you’re done, tap the red status bar at the top of the screen and confirm to stop.
If you don’t see the microphone option, make sure your iPhone’s microphone is not blocked by a case or screen protector, and that you haven’t denied microphone access to the Control Center in Settings > Privacy & Security > Microphone.
What to Do If the Microphone Is Already On
If you’ve enabled the mic and still get no sound, try these troubleshooting steps:
- Check the volume: Turn up the volume with the side buttons or in Control Center. The screen recording captures the device’s output volume, so if it’s muted, the recording will be silent.
- Restart the recording: Stop the recording and start a new one. Sometimes the audio session gets stuck.
- Restart your iPhone: A simple reboot can fix temporary glitches in the audio system.
- Update iOS: Go to Settings > General > Software Update to ensure you have the latest version, as bugs are often fixed in updates.
- Check the recording file: Open the video in the Photos app and look at the audio waveform in the editing tools. If there’s a flat line, the recording truly has no audio.
If you’re recording an external app (like a game or a streaming service), some apps block audio capture for copyright reasons. In that case, the recording will have video but no sound, and there’s no system-level fix.
How to Record Sound from Both the Mic and the App
By default, enabling the microphone replaces the app audio with the mic audio. You cannot record both simultaneously using the built-in screen recorder. If you need both, you have two options:
- Use a third-party screen recording app that supports mixed audio (e.g., some apps allow you to record the screen and mic together).
- Record the screen with the mic off, then separately record your voice with a voice memo app, and combine the two in a video editor.
This limitation is a common misconception—many users think the mic icon adds to the existing audio, but it actually switches the audio source.
Why the Screen Recording Button Might Be Missing
If you don’t see the screen recording button in Control Center at all, you need to add it. Go to Settings > Control Center, then find “Screen Recording� in the list and tap the green + button to add it. Once added, it will appear in Control Center. This is a common issue for users who have customized their Control Center and removed the button accidentally.
How to Extract Audio from a Screen Recording
If you already have a screen recording with no sound, you can’t add audio back to it without editing. However, if you have a recording with sound and want to extract just the audio, you can use the Photos app’s export feature or a third-party converter. On a Mac, you can open the video in QuickTime and use “Export As� to save only the audio. On iPhone, you might need a dedicated audio extraction app. This is useful for turning a screen recording into a podcast or a voice memo.
Frequently Asked Questions
Why does my screen recording have no sound even with the mic on?
If the mic is on but you still get no sound, check that the app you’re recording isn’t blocking audio capture. Also, ensure the phone’s volume is up and that you haven’t accidentally muted the microphone in the Control Center menu. Restarting the recording often helps.
Can I record my voice and the app sound at the same time?
No, the built-in screen recorder cannot record both simultaneously. You can either record the app sound (mic off) or your voice (mic on), but not both. For both, use a third-party app or combine separate recordings in editing.
Does the silent switch affect screen recording sound?
The silent switch (the physical switch on the side) mutes ringers and alerts, but it does not mute media audio. So if you’re recording a video with sound, the silent switch won’t silence it. However, if you’re recording a phone call, the call audio might be affected.
Why is there no sound in screen recording when using AirPods?
When using Bluetooth headphones, the screen recording might capture audio from the headphones’ microphone instead of the iPhone’s mic. This can cause low or no sound if the headphones are not properly connected. Try disconnecting the Bluetooth device and using the built-in mic.
How do I add sound to an existing screen recording?
You can’t add sound to a video that was recorded without audio using the Photos app. You’ll need a video editing app that allows you to add an audio track. Import the video, add a separate audio file (like a voice memo), and export the new video.
