How to fix an iPhone 11 with no sound, audio functions not working

Missing important phone calls or alarms is no fun. But bad things like these can happen especially if your phone is enduring some audio or sound problems. Audio problems in mobile devices are often attributed to hardware damage like when some audio components like microphones and speakers get busted. Nevertheless, there are some instances when the symptoms are inflicted by software-related factors including rogue apps, incorrect settings, and faulty updates. There are also other cases where the problem is isolated to certain applications. With that said, performing some basic troubleshooting is still imperative to rule out software-related triggers fixing any existing hardware damage. Lined up below are simple workarounds that are used to deal with a similar issue on the recently released iPhone 11 handset. Read on to learn what to do if audio functions aren’t working or your iPhone 11 has no sound.

Troubleshooting an iPhone 11 no sound problem, audio bug fixes

Software-related factors that ruined your iPhone’s sound functions can be ruled out using any of the following procedures. Here are a few workarounds you can try on before taking a trip to a service center. You can use any sound-enabled apps when testing your iPhone after applying each of these subsequent solutions.

Before you begin, check your phone’s volume level to make sure it isn’t set to the lowest mark. The placement of the physical volume controls makes it very possible to accidentally flip the volume up or down, especially if you’ve configured your device to enable volume adjustment using the hardware keys. To make sure the volume isn’t the problem, press the volume up key several times until it reaches the maximum level. If your iPhone still has no sound after adjusting the volume level through the physical buttons, then you may start eliminating other possible software-related causes.

 

First solution: Toggle the ringer switch off and on again.

Minor errors affecting binary features of an electronic device including the iPhone are usually dealt with by simply turning the feature off and then back on again. This simple tweak somehow refreshes the glitching feature and then gets it back to normal. With that said, the sound problems on your iPhone inflicted by random system errors can also be resolved by simply toggling the ringer switch off and then back on again. If the ringer is already turned on when your iPhone has no sound, then you can toggle it off and then back on.

The ringer switch is located on the upper-right side of your phone. If you see an orange bar/line on the switch, it means that the phone is mute. In this state, you won’t hear any sound coming from your device. But if you don’t see the orange bar, your phone is on ring mode and thus, sound outputs should be audible. 

Also consider turning the ringer volume of your iPhone all the way up. Just follow these steps, if you haven’t already:

  1. Tap Settings from the Home screen.
  2. Select Sounds & Haptics.
  3. Scroll to the Ringer and Alerts section.
  4. Then drag the Volume slider to the right until it reaches the maximum level.
  5. To prevent unwanted or unexpected volume adjustments with the physical volume controls, simply turn the Change with Buttons switch OFF.

If this doesn’t solve the problem and you still don’t hear any sound coming from your iPhone, try the following methods to rule out other factors.

 

Second solution: Reboot or soft reset your iPhone that has no sound.

Rebooting your iPhone can also fix various types of software errors including those halting the audio system. Thus, if you haven’t already, reboot or soft reset your iPhone 11 with these steps:

  1. Press and hold both the Side and Volume Up buttons for a few seconds.
  2. Release both buttons when the Slide to Power off bar appears.
  3. Swipe or drag the bar to turn your device off.
  4. After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.

This doesn’t affect any saved data on your iPhone storage, so there’s no need to worry of losing any important files. 

Junk files including corrupted temporary data stored among other cached files are also cleared out by a soft reset. 

 

Third solution: Disconnect your iPhone from any Bluetooth-enabled devices.

Another possible reason as to why you don’t hear any sound coming from your iPhone is because it’s currently paired with or connected to a Bluetooth device. This is often the case if Bluetooth is enabled on your device. To make sure that sound outputs from your iPhone are not bypassed and routed to a Bluetooth-enabled audio device, follow these steps to turn Bluetooth off or forget Bluetooth devices:

  1. From the Home screen, tap Settings.
  2. Scroll down and select Bluetooth.
  3. Toggle the Bluetooth switch to turn the feature OFF.

You can also forget all saved Bluetooth devices from your iPhone. Doing so will prevent your device from automatically pairing with any Bluetooth-enabled devices within range after a soft reset.

Fourth solution: Check and manage Do Not Disturb settings, Attention Aware Features on your iPhone 11.

As the name implies, DND or Do Not Disturb feature can stop sound alerts from working on your device. It’s another way to mute your iPhone. If this feature is enabled, all sound outputs, except for alarms are disabled. With that said, you won’t hear any sound for incoming calls, messages and app notifications unless you’ve set some exceptions. To make sure this isn’t barring your iPhone 11 from producing any sound, follow these steps to disable DND feature:

  1. Tap Settings from your Home screen.
  2. Scroll to and select Do Not Disturb.
  3. Then toggle the Do Not Disturb switch to turn the feature OFF.

Aside from DND, there’s also another iOS feature that you should consider checking and turning off, if necessary.

Some owners of new iPhones who have faced relevant audio problems from very low sound to no sound out all were able to find solution by disabling Attention Aware Features on their respective devices. What actually happens is that when this feature is enabled, the TrueDepth camera of your device will evaluate if you are paying attention and if thinks you are, it will automatically reduces the volume when you look at the screen while the phone is ringing or when an alarm is triggered. All these are done through facial recognition. This feature is only available in iPhone variants with Face ID. If you wish to try your luck in this tweak, then you may try adjusting this feature on your iPhone settings. Just follow these steps:

  1. From the Home screen, tap Settings.
  2. Select Face ID & Passcode.
  3. Scroll down to Attention Aware Features then toggle the switch next to it to turn the feature off.

Deselecting or turning off Attention Aware features, will keep the ringer and alert volume even when you pick up and look at your phone.

You can also access and manage this feature from your phone’s accessibility menu. Here’s how to get there:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Tap Accessibility.
  4. Select Face ID & Passcode.
  5. Finally, toggle the Attention Aware Features switch to turn the feature OFF.

Then check and see if all these changes resolved the no sound problem on your iPhone 11.

 

Fifth solution: Install available firmware updates for your iPhone 11.

Should the audio problem you’re dealing be attributed to some malware or software bugs, installing the latest firmware update on your device will likely fix it. If you haven’t yet installed the latest iOS version on your iPhone 11, follow these steps to check and update your iPhone software wirelessly:

  1. Tap Settings from your Home screen.
  2. Select General.
  3. Tap Software Update.

Read and review any update notification and then select the option to download and install the available update on your phone.

 

Last resort: Erase your iPhone and restore its factory default settings.

If all else failed to fix the problem and your iPhone still has no sound, you may opt to troubleshoot further and rule out complex system errors by performing a factory reset. This reset will erase everything from your iPhone system including saved files, personal preferences, downloaded apps, and other personal information. Any complex system bugs, malwares and complex errors are also eliminated. Just follow these steps if you wish to proceed:

  1. From the Home screen, tap on Settings.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Tap Erase all content and settings from the given options.
  5. Enter your passcode if prompted to continue.
  6. Confirm action by tapping the option to erase and reset your iPhone.

When the reset is finished, you can use the start-up wizard to set your iPhone up as new. Be sure to set the volume to the maximum level to make sure sound outputs are audible.

 

What to do if audio functions still don’t work and your iPhone 11 still got no sound after carrying out the given solutions?

At this point, there’s a better chance that hardware damage is present on your device. It may be hard to believe but any new devices can acquire some sort of physical or liquid damage, especially when accidental drops or liquid exposure occurred. In the case where the no sound problem arises among other possible factory defects, contact your iPhone provider immediately to report the issue and avail for iPhone warranty. You can also visit the nearest Apple-authorized service center in your place and have your device scrutinized by an iPhone technician for hardware assessment.
