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: Conflicts between audio sources
One of the things that makes smartphones so smart is the fact that they allow us to do multiple different things at once. We can check our emails while we’re on a phone call or listen to a podcast while we kill time by playing a game.
Unfortunately, a byproduct of this is that using the audio on your device when you start screen recording can interfere with your phone’s ability to capture sound. You may find that it doesn’t record sound at all, or that it does record sound but that two or more sound sources are clashing with one another.
To avoid this, close any apps that might be using the audio on your iPhone before you start the recording. It can be worth force quitting all of your apps except for Movavi Screen Recorder and the app you want to record. As well as avoiding conflicts between audio sources, that will also make sure that your phone is running at full speed.
Issue 8: Bluetooth interference
If your iPhone is paired to Bluetooth devices – and to wireless speakers and wireless headphones in particular – then you may find that those devices are taking over your audio output and interfering with your recording.
Luckily, there’s an easy way to combat this: just disconnect any paired Bluetooth devices before you start recording.
There are different ways of doing this, from turning on airplane mode to disabling Bluetooth. You can also open up the Settings app and select Bluetooth so that you can manually toggle devices one by one.
Once you’ve updated your Bluetooth settings, be sure to take a test recording first to make sure that everything is working as it should be and that the audio is being recorded properly.
Issue 9: Faulty microphone hardware
If your iPhone screen recording has audio but it’s scratchy, muffled or distorted, there’s a good chance that there’s a problem with your hardware. After all, we know that your phone is technically capable of recording, it’s just that the final product doesn’t sound quite like it should do.
When this is the case, there are a range of potential culprits to consider, from debris blocking the microphone ports to physical damage to the microphone or loose wiring within the device.
Troubleshooting faulty hardware can be difficult, but you can get started by testing the microphone by using the Voice Memos app to record a short audio clip. If there’s no sound when you play it back – or if there’s distortion and interference – then you should take a close look at the ports on your device and clean them carefully to remove any debris.
If that doesn’t solve the problem, your best option is to contact Apple Support or to pay an in-person visit to your local Apple Store so that they can take a look at your device.
