First solution: Flip the ringer switch up or down.

This trick has been proven effective by many iPhone users who have dealt with random no sound problems attributed to software glitches. It helps refresh the iPhone’s audio functions. Make sure the switch is not rested on the Silent mode position though. Here’s what to do then:

  • From the top left corner of your iPhone 8 Plus, flip the Ringer switch to turn Silent Mode on. Doing so turns off sounds on your iPhone. You will see the switch is in red/orange position and the silent mode or ringer notification briefly shows up on screen.
  • After a few seconds, flip the switch again to set it back to ringer mode.

If the switch appears to be stuck, try to remove any case from your iPhone to ensure that the switch isn’t blocked.

Second solution: Reboot your iPhone 8 Plus.

Random glitches could be affecting the current audio application you’re using so it is possible that the no sound issue is just isolated to an app in use. It can happen and usually happens. And a simple yet very effective solution to this is a soft reset or simple reboot on your iPhone. So here what you should do if this is the first time your iPhone 8 Plus makes no sound:

  1. Press the Side/Power button for a few seconds until you see the Slide to Power Off screen.
  2. Drag the slider to turn your iPhone off completely.
  3. And then after 30 seconds, press Power to turn the iPhone back on.

Alternatively, you can restart your iPhone forcibly (force restart) with these steps:

  1. Press and quickly release the Volume Up button.
  2. Then press and quickly release the Volume Down button.
  3. And finally, press and hold the Side/Power button until the Apple logo appears.

Both of these restarts won’t affect any of your iPhone data so expect that everything will stay intact on your phone’s internal memory after the process.

Third solution: Toggle Bluetooth on or off.

Turning Bluetooth on for a few seconds and then off again can also help if your phone refuses to make sound after you disconnect it from a Bluetooth accessory. It’s possible that the phone still thinks that it’s paired or connected to Bluetooth so you need to refresh its memory. Here’s how:

  1. Tap to open Settings.
  2. Tap Bluetooth.
  3. Then tap the Bluetooth switch to turn the feature off.

Alternatively, you can swipe your finger up from the bottom of the screen to bring up the Control Center and then tap the Bluetooth icon from the Control Center to enable and disable Bluetooth on your iPhone 8 Plus.

Fourth solution: Reset all settings.

Incorrect settings can also be the underlying cause of the problem.

After the reset, your iPhone reboots .Wait until it boots up completely then try to check if sound or audio functions are already working as intended.
