When you don’t hear any sound on your iPhone 12 Pro, there are several steps you can take to fix the issue. Follow the troubleshooting steps below to fix iPhone 12 Pro audio issues.
One of the problems that can be quite annoying is when your iPhone 12 Pro is not delivering any sound. If you hear no sound on iPhone 12 Pro, don’t think you won’t be able to fix it. Most of the time, the iPhone 12 Pro sound issues can be solved with a few troubleshooting steps. You don’t need to have any special tech skills to try them out. Put some effort and be patient especially if the first few solutions don’t work for you.
Remove The IPhone Case
Before we start the software troubleshooting steps, make sure you have removed your iPhone case if you are using one. The case of your device can somehow cover the speaker holes and cause iPhone 12 Pro no sound problems.
Test the iPhone speaker
Go to Settings > Sounds & Haptics. Under Ringers and Alerts, move the slider to the right to increase the volume. If you hear a sound, the iPhone speaker works. If you don’t hear a sound, the device may need a hardware repair.
Turn Off Change With Buttons.
If you are still experiencing iPhone 12 Pro audio issues, you may proceed with turning off ‘Change With Buttons’. Luckily, some users stated that turning off this setting resolved the iPhone 12 Pro speaker audio issues.
On top of that, turning off ‘Change With Buttons’ will enable you to lock the volume settings under the ‘Ringer and Alerts’. Doing this should prevent the issue from happening. Go to Settings Sounds & Haptics and turn off the switch next to Change with Buttons.
Adjust the Ring/Silent switch
The Ring/Silent switch, also called the Mute switch, has two positions. When the switch is pushed toward the back of the device, the color orange indicates that the switch is set to silent mode. Push the switch toward the screen to enable sound.
Turn off Do Not Disturb
Do Not Disturb mode silences many sounds and alerts. Turn it off if you don’t hear any sound. Open the Settings app, select Do Not Disturb, then move the toggle switch to the Off position.
When your iPhone is connected to a Bluetooth audio device, it sends sound to the device and not to the speaker on the iPhone. Turn off Bluetooth so that sounds play from the iPhone.
Adjust the volume buttons while in an app
Sometimes the sound volume in an app may be turned down too low to hear. Open an app, such as Music, Podcasts, or any other app that uses sound. Use the hardware volume buttons on the side of the iPhone to turn up the volume.
It may also be that the sound setting in the app is too low. Open the app and navigate to the page with the Play/Pause button. Move the slider to the right to increase the volume.
Check third-party app sound settings
Many third-party apps offer customized volume and mute sound settings. For example, some games offer separate settings for volume, music, sound effects, ambient audio, and more.
In the app, look for audio or sound settings. Turn off any customized mute options, enable audio, and adjust the volume sliders to increase volume. Depending on the app, either move sliders up, move sliders to the right, or tap an icon to make it active.
Check notification settings for the app
Check the iPhone notifications’ sound settings for the app. Some apps, such as Reminders and Messages, let you choose a notification sound. If this sound is set to None, the alert is silent. Choose None and select a sound.
Plug the headphone into the Lightning port. (The charging cable also connects to this port.) Listen for audio with the headphones while using an app that has audio.
Alternatively, plug in and then remove the headphones, then listen for audio. It could be the iPhone is stuck in headphone mode.
Restart the device
If you still don’t hear any sound, restart the iPhone. To restart, turn the iPhone off and then back on.
Check for app updates
In rare cases, the lack of sound may be the result of an app developer error. Go to App Store > Updates to check if an app update is available. If you see only apps in the Updated Recently section, no additional updates are available.
Check for iOS updates
An iOS update might fix a sound problem. Check for any system software updates from Apple, then download and install the available updates.
Reset all settings
If none of the above steps resolve your iPhone 12 Pro audio issues, reset the iPhone settings. This resets the sound, display, and network settings to the iPhone defaults. Go to Settings > General > Reset > Reset All Settings.
Contact Apple Support
If none of the above steps fixed your iPhone 12 Pro sound issues, you may have a hardware problem. Whatever the issue, your only course is to contact Apple support.
