Part 1: Check if the iPhone is on Silent or Do Not Disturb

Before diving into advanced troubleshooting, start with the basics, check if your iPhone is accidentally muted or in Do Not Disturb mode. It might sound simple, but this is one of the most common reasons why users report that their iPhone video has no sound.

Step 1: Turn Off the Mute Switch

Locate the small switch just above the volume buttons on the side of your iPhone.
If you see an orange line, it means silent mode is active. Flip the switch so the orange is no longer visible.

Step 2: Disable Do Not Disturb or Focus Mode

• Swipe down from the top-right corner of your screen to open the Control Center.

• Look for the Focus or Do Not Disturb icon (a moon symbol).

• If it's enabled, tap it to turn it off.

  
  

Step 3: Turn Up the Volume

• Use the volume up button to ensure your device is not set too low.

• Alternatively, go to Settings > Sounds & Haptics and adjust the slider under "Ringer and Alerts."

Honestly, this fix has saved me more times than I'd like to admit. If you're like me and tend to switch your phone to silent during meetings or focus sessions, you might forget to switch it back. Many people panic when their iPhone videos have no sound, but often it's just the mute or Focus setting getting in the way. Try this first before moving on; you might be surprised how often it works.

Part 2: Clean the Microphone and Speaker Grills

If your iPhone video has no sound recorded, the issue might not be software-related; it could be physical. Dust, dirt, or debris blocking your microphone or speakers can result in muffled or completely silent video recordings.

Step 1: Inspect Your iPhone's Microphone and Speakers

• Check the microphone, which is located at the bottom of your iPhone, near the charging port.

• Also, inspect the speaker grills on the bottom and next to the front camera.

Step 2: Clean Gently

• Use a soft-bristled brush, a microfiber cloth, or a can of compressed air.

• Gently brush or spray the areas to remove dust and dirt.

• Avoid using sharp objects that could damage the mesh or push debris further in.

Step 3: Record and Test

• Open your Camera app and record a short video.

• Play it back to check if the sound has returned.

• Alternatively, use the Voice Memos app to test if your iPhone video voice not working issue is resolved.

Bonus Tip: Use Voice Memos for Quick Testing

Voice Memos is a fast way to test if your microphone is working. Open the app, record a quick memo, and play it back. If there's no sound here, the microphone is likely still blocked or malfunctioning.

This method helped me identify a sneaky culprit once: pocket lint. I had no idea that such a small amount of debris could affect video sound so drastically. If your iPhone videos have no sound, especially after recording, don't underestimate how much a simple cleaning can fix.

Part 3: Re-enable App Permissions or Restart Apps

Sometimes the problem isn't with your iPhone itself, it's with specific apps. Apps like Camera, Instagram, or WhatsApp may lose microphone access, causing newly recorded videos to be silent. This is a common reason users report that their iPhone videos have no sound.

Step 1: Check App Microphone Permissions

• Go to Settings > Privacy & Security > Microphone

• You'll see a list of apps that have requested mic access.

• Make sure the toggle is enabled for the app you're using (e.g., Google, WhatsApp).

Step 2: Force Quit the App

• Swipe up from the bottom of your screen and pause in the middle to open the app switcher.

• Swipe the problematic app upward to close it.

Step 3: Restart the iPhone

• Hold the side button and volume up/down button together.

• Slide to power off.

• Wait a few seconds, then turn it back on.

I once had a situation where videos recorded inside Instagram had no audio, but those recorded in the Camera app were fine. Turns out the mic access had been turned off for Instagram after a recent update. So if your iPhone videos have no sound issue, it is limited to one app; this fix could be all you need.

Part 4: Fix iOS Bugs by Updating or Resetting Settings

If none of the earlier solutions worked and your iPhone video has no sound, the issue might be rooted in the system itself. Minor iOS glitches or buggy settings can silently cause audio malfunctions during recording or playback.

Option 1: Update Your iOS

• Go to Settings > General > Software Update

• If an update is available, tap Download and Install

• Follow the on-screen prompts and restart your iPhone

Option 2: Reset All Settings (Non-destructive)

• Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings

• This will reset preferences like Wi-Fi passwords, layout, and system settings.

• It does not delete personal data like photos or videos.

Tip: Back Up First

Even though this reset doesn't erase your data, it's good practice to back up your iPhone via iCloud or iTunes before making any major system changes.

When my recorded video had no sound on my iPhone, I went through all the hardware fixes and permission settings, but nothing worked. But updating iOS finally resolved it. It's amazing how one tiny bug can affect sound in apps without you realizing it. And if an update doesn't help, resetting all settings is your next best move; it's safe and surprisingly effective.

FAQs

Q1: Why does my iPhone record video with no sound?

There are several possible reasons. It could be due to a blocked microphone, muted device settings, denied app permissions, or even a glitch in the iOS system. If your iPhone video has no sound recorded, checking physical and software issues step-by-step is the best approach.

Q2: How do I fix iPhone video playback with no audio?

Start by checking the mute switch, volume settings, and Do Not Disturb mode. If those aren't the issue, test your speakers, clean the microphone grills, and ensure apps have microphone access. These simple steps can often resolve the no sound on iPhone video problem.
