2 Ways to Fix No Audio When Recording Videos on iPhone

Basic Troubleshooting

• Unmute the audio – This isn’t a solution to the problem but a step that can verify whether there is a problem in the first place. It could be possible that the video you’re trying to play has proper audio, but you have not unmuted it in the Photos app.
• Don’t block the mic when holding the phone – A common cause of no audio when recording videos on an iPhone is people accidentally blocking the microphones. This can also lead to low or muffled audio when recording videos.
• Disconnect Bluetooth or wired headphones – The iPhone supports audio capture via an external mic. So, it’s possible that the mic of external headphones will be employed. Disconnect them and record again.
• Force quit Camera – The Camera app may have a glitch that prevents audio from being captured when recording videos. Restarting the app might do the trick.
• Force restart iPhone – A force restart can sometimes fix common issues on your iPhone. Hopefully, it can resolve the bug or setting-related issue causing the no audio when recording on iPhone issue.

Fix 1. Check Mic With Voice Memo

The idea is simple: check whether the mic is working fine. To do so, open the Voice Memos app and record something. If it plays perfectly, the issue is with the Camera app.

However, if you encounter issues while recording the memo, your iPhone’s mic is not working. Try cleaning the microphone/speaker with a microfiber cloth. If nothing works, contact Apple Support for assistance.

Fix 2: Reset All Settings on iPhone 

When your Camera app is the troubling party, this is the last resort. However, when you reset all settings, you might lose stored passwords, Wi-Fi connections, etc., so be mindful.

Step 1: Go to the Settings app > tap General.

Step 2: Scroll and select Transfer or Reset iPhone.

Step 3: Next, select Reset > choose Reset All Settings from the option.

Step 4: Enter your device passcode to confirm.

If the problem persists after trying the above solutions, the mic on the iPhone might have a hardware defect. It’s best to visit a service center to have your iPhone checked.
