The iOS 15 update has come with a plethora of features and has attracted many iPhone users to upgrade their iDevices to iOS 15. However, some users have reported sound not working on iOS 15, which is one of the most common errors that many users have encountered after installing the latest software update. If you are also facing the same issue, this guide will help. In this article, we have shared the most effective ways to fix no sound on iOS 15 all by yourself.

So, without any further ado, let’s dive in.

Part 1. Can the iOS 15 update make my iPhone no sound?

While the iOS 15 update doesn’t have a direct impact on your iPhone’s speakers, it may enable a few settings that could result in sound not working on 15. For instance, many users who installed iOS 15 beta versions on their devices have reported that the update automatically enabled DND (Do Not Disturb Mode) on their devices. If that’s the case, you won’t be able to hear any sounds whatsoever except for alarms.

Part 1. 13 Tips to Fix Sound Not Working on iOS 15

Tip 1: Turn on the Mute Switch

In many cases, the iPhone sound not working issue is caused due to the “Mute Switch” button, most commonly known as “Ring/Silent Switch”. You might have accidentally put your device in silent mode during the update. So, simply turn off the silent mode by flicking the Silent switch to the other side.

Tip 2: Turn up the Volume Level

If the Ringer switch is on and you’re still unable to hear any sounds on your iPhone, it might be possible that its volume is set to a lower level. In this case, all you have to do is swipe to launch the Control Center and use the volume slider to adjust the volume levels. Alternatively, you can also press the Volume up button to increase the volume and hear all sounds clearly.

Tip 3: Disable DND (Do Not Disturb)

You may still doubt that why is my volume up but no sound on iOS 15. As we mentioned earlier, an iOS 15 software update can also enable the DND mode on an iPhone. In this situation, you can simply go to “Settings” and click “Do Not Disturb”. Then, toggle the switch off to disable DND mode. Now, launch YouTube or any other apps and see if you’re able to hear sounds on your device or not.

Tip 4: Turn off Bluetooth

Though it may seem a bit hard to digest, turning off Bluetooth can also fix my iPhone no sound on iOS 15. How? Well, there are many situations when the device is connected to an external audio output source, be it AirPods or Bluetooth speakers. As long as you don’t disconnect your iPhone, you won’t be able to hear anything on its speakers. So, make sure to disable the Bluetooth on your device and see if this resolves the issue or not.

Here are the 2 routes:

Go to “Settings” and tap “General” option. Find the Bluetooth and turn it off.

Go to Control Center and switch Bluetooth off.

Tip 5: Using Headphones

If you’re using an earlier model of iPhone that still has the headphone jack, it might be the reason behind the sound not working on iOS 15. So, grab your earphones and insert them into the headphone jack. Wait for a few seconds and quickly unplug them again. Repeat this process a few times until you can hear all the sounds clearly.

Tip 6: Clean Debris

Over time, the earpiece and speakers tend to accumulate debris, which may damage the audio output of the iPhone. You can avoid this scenario by regularly clearing out debris from the earpiece, speaker, and headphone jack. To do this, use a clean piece of cloth to gently wipe the surface. Make sure that the cloth is dry. Instead of using water, rub the earpiece and speaker with rubbing alcohol.

Tip 7: Restart your iPhone

If you’re still unable to hear any audio on your iPhone, the next step would be to restart the device. In some cases, sound not working on iOS 15 can occur due to a random system error.

Restart iPhone 13, X, 11, or 12

  1. 1. Press and hold the power button and volume button (one of the two) at the same time.
  2. 2. Drag the slider and wait for about 30 seconds.
  3. 3. To restart your iPhone, press and hold the side button until Apple logo shows up.

  3. 3. To restart it again, press and hold the side button or the top button (iPhone 5 or Earlier) until Apple logo appears.

Once the iPhone is restarted, you’ll be able to hear all the sounds without any lags.

Tip 8: Check iPhone Speaker

If you’re still unable to hear any sounds on your iDevice, there’s a huge probability that the speakers might be damaged. You can use Apple’s built-in tool to check if speakers are working or not. To do this, click "Settings" and tap on "Sound & Haptics". Scroll down and swipe the slider to the right under the "Ringers & Alerts" tab. If you hear a sound, the speakers are working fine; otherwise, you’ll have to visit the repair center to get them repaired.

Tip 9: Allow Notifications

Many users who deal with no sound issue only for a few apps on their device. For instance, the device will play all the other sounds, except for the notification tunes for a few selected apps. If that’s the case, go to "Settings" and click “Notification Settings”.

Then, scroll down to the end of the screen and click on the app whose notifications you’re not hearing. On the next screen, toggle the switch next to the “Allow Notifications” and “Sounds” options. Go back to the home screen and check if you’re hearing all the sounds or not.

Tip 10: Reset All Settings

Resetting all settings is also a great way to fix the sound not working on iOS 15 issue. Sometimes, the new software update overrides the existing audio settings, which may alter the audio output configurations. In such a situation, resetting all the settings will help you reconfigure the audio settings and fix the error.
  1. Step 1. Open “Settings” and click “General”.
  2. Step 2. Scroll down and click on “Reset”.
  3. Step 3. Tap “Reset All Settings” and enter the screen passcode to authorize your actions.

After the device is reset successfully, check if it’s playing the audio properly or not.

Tip 11: Factory Reset

If the error persists, you can also reset your device completely to troubleshoot the error. Factory reset will restore all the settings to default and fix all the random system errors as well. Here’s how to factory reset your iPhone.

  1. Step 1. Inside the “Settings” app, click “General”.
  2. Step 2. Tap “Reset” and then click “Erase all Content and Settings”.

Tip 12: Check App Updates

If you are running the iOS 15 beta version on your device, it’ll be crucial to check for software updates every now and then. Apple keeps releasing stable versions almost every day, which has fewer bugs as comp[ared to the previous update. So, go to “Settings” and make sure to upgrade iOS 15 to the latest available software update.
