My iPhone camera video has no sound

Hello chubindra,

Welcome to Apple Support Communities. 

We understand that you’re not hearing sound from a video. We are happy to help.

Was the video recorded with no sound? Does this happen with any video you watch? Was this video recorded by you using the iPhone camera app or another app? These answers will help us isolate the cause further.

Let’s start by trying the steps here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

"Follow these steps

1. If your device has a Ring/Silent switch, move the switch forward—toward the device's display—so that orange isn't showing. If you're using an iPad, you can also swipe down from the top-right corner to open Control Center and make sure that Silent Mode is off. 

2. Open Settings > Focus > Do Not Disturb and make sure that Do Not Disturb is off.

Contact Apple Support

If you checked the sound settings and your device still has sound issues, contact Apple Support to discuss service options.

If you want to try more steps on your own

If you prefer, here are some more steps you can try on your own. After following these steps, you might still need to contact Apple Support to discuss service options.

1. Remove all screen protectors, films, or cases from your device. 
2. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty. 
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.
4. Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.
5. If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location."

We also recommend checking to see if your microphones are working as expected: If the microphones on your iPhone aren't working - Apple Support

"Clear the microphones

1. Remove any screen protectors, films, or cases from your iPhone.
2. Clear any debris from the openings of your iPhone. 

Contact Apple Support

If you still sound unclear during calls, recordings, or apps, contact Apple Support to discuss service options.

If you want to try more steps on your own

If you prefer, here are some more steps you can try on your own. You might still need to contact Apple Support after following these steps.

If people can't hear you on phone or FaceTime calls

1. Open the Voice Memos app. 
2. Tap the Record button , speak at the bottom of your phone, then stop the recording. 
3. When you play back the memo, you should hear your voice clearly.

If people can't hear you when you're using speakerphone 

1. Open the Camera app.
2. Record a video while speaking at the top of your iPhone.
3. Tap the camera chooser  to switch to the other camera. Then record another video while speaking at the top of your iPhone.
4. When you play back the videos, you should hear your voice clearly.

If the microphone doesn't work in a specific app

1. Go to Settings > Privacy > Microphone.
2. Make sure that the app is enabled.
3. If the app has permission to access your microphone, or if it isn't listed, contact the app developer."
