Issue 5: You’re using one of the apps that don’t allow recording
Apps that use copy-protected content are likely to block any attempts of recording both audio and video. So if you’re trying to record content from such apps as Apple Music or Amazon Music, there will be no audio in the recording. The sound will be muted as soon as you start recording.
The same applies to video- and voice-conferencing apps like WhatsApp, FaceTime, and Messenger. These apps don’t allow audio recording during voice/video calls for privacy reasons. So if you’re wondering, “Why does my screen recording not have sound?”, this could be the reason.
Issue 6: Screen-recording icon is grayed out
If your screen recording button is unresponsive or grayed out, the issue could stem from restrictions set within the device. Apple engineers worked in this control to prevent inadvertent screen recording. The button could also be disabled due to parental controls.
To resolve this, navigate to your iPhone's settings and tap Screen Time. Go into Content & Privacy Restrictions, enter your Screen Time passcode if prompted, and then tap Content Restrictions. Scroll down to Screen Recording and make sure it’s set to Allow. This should enable your screen-recording functionality.
Issue 7: Interference from other audio sources
If other apps are using the audio on your device when you begin a screen recording, they may interfere with the phone’s ability to capture sound. For instance, if you have music playing in the background or are on a call, the screen recorder may not pick up any additional audio.
Make sure to close any apps that might be using the audio source on your iPhone before you start the screen recording. Double-check that music, video players, or any other active audio apps are completely shut down. This ensures that the screen recorder can capture the audio without any external interference.
Issue 8: Bluetooth interference
If your iPhone screen recording has no sound, paired Bluetooth devices may take over the audio output. This is common with wireless headphones or speakers that may redirect audio away from the device's internal capture capabilities.
To prevent this, disconnect any paired Bluetooth devices before initiating a screen recording. You can do this by going to Settings > Bluetooth and toggling off the devices listed, or by disabling Bluetooth entirely. Test the screen-recording function afterward to ensure the audio is recording through the iPhone's built-in microphones or speakers.
Issue 9: Faulty microphone hardware
If you get an iPhone screen recording with sound issues – scratchy or muffled sound – you could have a hardware issue. This could be due to physical damage, debris blocking the microphone ports, or a system malfunction.
Test the microphone by using the Voice Memos app to record a quick memo. If there's no sound on the playback or the quality is poor, inspect the microphone ports for debris and clean them carefully. If the problem persists, consider contacting Apple Support or visiting an Apple Store for a hardware check. It's crucial to ensure that the microphone is functional for the screen-recording feature to work correctly.
