Having issues with no sound coming from your iPhone can be incredibly frustrating. Whether you are trying to listen to music, watch videos, or make phone calls, not being able to hear anything makes your iPhone much less useful.
The good news is that in most cases, sound issues on an iPhone can be easily resolved. Here are some of the most common reasons why you may not be hearing sound from your iPhone and how to fix them.
Make Sure Nothing is Plugged Into the Headphone Jack
One of the most obvious but often overlooked reasons why your iPhone may not be outputting sound is if something is plugged into the headphone jack. If you have headphones, earbuds, or an auxiliary cable connected to your iPhone’s headphone jack, sound will not come through the external speakers.
To rule this out, check to make sure that nothing is plugged into the headphone jack on the bottom of your iPhone. If you find something plugged in, unplug it and sound should resume playing through your iPhone’s speakers.
Check the Volume Settings
Another simple setting to double check is your iPhone’s volume. Make sure that the volume is turned up and not muted. You can check this by using the volume buttons on the side of the iPhone or by going into Settings > Sounds to check the different volume sliders.
Things to look for:
- The Ringer and Alerts slider should be turned up
- The toggle next to Change with Buttons should be turned on
- The Media Volume slider should be turned up
- The iPhone should not be in silent mode (the toggle next to Ring/Silent should be set to Ring)
Make sure none of these volume settings are turned all the way down or muted. Turning them back up may resolve your sound issues.
Check for Debris in the Speakers/Headphone Jack
It’s possible for debris like lint or dirt to get lodged into your iPhone’s speakers or headphone jack, which can block sound from getting through. If this debris accumulates over time, it can muffle the sound quality or cause no sound at all.
Carefully inspect the speakers along the bottom edge of the iPhone as well as the headphone jack for any signs of debris buildup. You can try using a toothpick or a soft brush to gently clean out the speakers or headphone jack. Make sure not to use anything metal or sharp that could further damage the ports.
Restart the iPhone
Restarting your iPhone essentially resets all components and connections on the device. If there is some software, network, or hardware issue that is causing sound problems, restarting the iPhone can clear out any problematic settings and get sound working again.
To restart an iPhone 8 or earlier, press and hold the Power button until you see the “slide to power off” prompt appear. Slide it, then wait 30 seconds before pressing and holding the Power button again to turn your iPhone back on.
For iPhone X or later, press and release the Volume Up button. Press and release the Volume Down button. Then, press and hold the Side button until you see the Apple logo appear.
Restarting your iPhone may take a minute or two but can help resolve transient sound problems.
Check for Software Updates
If there are any bugs in the version of iOS that is currently installed on your iPhone, it could result in issues like no sound. Apple regularly releases software updates to fix bugs and improve performance, so making sure your iPhone is updated to the latest iOS version can rule out software issues.
To check for updates, go to Settings > General > Software Update. If an update is available, tap “Download and Install” to update your iPhone to the latest iOS version. Having the latest software will ensure compatibility with all apps and system functions like sound output.
Reset Network Settings
Network connectivity issues can sometimes interfere with sound output on an iPhone. If you are connected to a Bluetooth device or Wi-Fi network, try disconnecting to see if sound returns. If not, resetting all network settings may help.
Go to Settings > General > Reset and tap Reset Network Settings. This will erase all Wi-Fi networks and Bluetooth pairings so you’ll have to reconnect afterwards, but it can resolve software bugs related to connectivity that may be preventing sound.
Check App and Media Settings
If you are trying to play sound from a particular app like Music, Videos, or a streaming service like YouTube, make sure that the sound is not turned off specifically within that app. Look for a settings cog or audio icon within the app to check that sound effects, media sound, or overall volume is not set to mute.
Similarly, if you are trying to play a certain song, video, or other media file, check that the sound for that individual file is not turned off. Some apps have options to play media silently or mute specific content while leaving overall sound enabled.
Update Apps
Outdated app versions can also be the source of sound issues on an iPhone. If apps are not fully compatible with the current iOS software or device hardware, problems like no sound may occur.
Open the App Store and tap your profile icon at the top right. On your profile screen, scroll down to see all apps installed on your iPhone and check if any have pending updates. Tap “Update” to download the latest versions of your apps which may contain critical bug and performance fixes.
Check Accessibility Settings
The Accessibility settings on your iPhone include options to mute sound or lower overall volume as an accessibility accommodation. If you or someone else has enabled any of these audio accommodations, it could explain missing sound.
Go to Settings > Accessibility and check that any audio accommodations like Mono Audio, Background Sounds, or Phone Noise Cancellation are disabled. Turning these special audio modes off may bring back normal sound output.
Factory Reset the iPhone
If you have exhausted all other troubleshooting options, a factory reset will erase your iPhone and restore it to default settings. This will clear out any problematic software or settings that could be causing sound issues.
Back up your iPhone data first through iCloud or iTunes. Then go to Settings > General > Reset and choose “Erase All Content and Settings” to wipe your iPhone back to factory conditions. You can then restore your data from the backup and test if sound is restored.
Hardware Problems
In some cases, sound issues may be caused by actual physical hardware damage or malfunction. Things to inspect for include:
- Accumulated debris, corrosion, or damage to the speakers/headphone jack
- Damaged audio cables and components
- Stuck or broken volume buttons
- Faulty microphone
- Display damage that may affect sound
If you see any evidence of hardware damage that could explain the missing audio, you may need to take your iPhone to an Apple store or repair shop to have it serviced. Hardware issues will likely persist even after software troubleshooting.
Get Your iPhone’s Audio Tested
To confirm if the sound issue is hardware-related, get the iPhone’s audio components tested at an Apple store or authorized repair shop. They can run diagnostics and determine if the speakers, headphone jack, or integrated circuits are malfunctioning.
Based on the results, they may be able to repair or replace the affected components to restore sound function if the issues are hardware-related. Be aware that out-of-warranty audio repairs can be costly depending on the parts needed.
Conclusion
Lack of sound from your iPhone can certainly be annoying, but the good news is that with some patient troubleshooting, you can likely resolve many common sound issues yourself. Make sure to methodically try the different suggestions around settings, software, cleaning, and hardware inspection outlined above.
Testing different situations like headphones versus speakers, various apps and media files, and rebooting or resetting your iPhone can help isolate where exactly the problem lies. If the audio troubleshooting steps do not work, seek professional help to determine if hardware replacement or repair is needed. With persistence, you will get to the bottom of your iPhone’s sound problems.
