The first recommended simple solution to software-related issues including no sound problems on an iPhone is a device restart or soft reset.

  2. Release both buttons when you see the Slide to Power Off prompt.
  3. Drag the slider to the right to turn your iPhone off.
  4. After 30 seconds, press and hold the Side/Power button until the Apple logo appears.

A soft reset doesn’t affect any data from your iPhone’s internal memory so there’s no need to create backups beforehand. You can expect all your data to remain intact after the restart.

If the problem occurs only when using a certain application, try to force quit the faulty app and then restart your iPhone. It’s probably just a minor app glitch that usually occurs to any other apps, which can easily be remedied by a restart or two.

Second solution: Flip the ringer switch.

Sometimes the audio system is triggered by some factors to act weird thus becomes erratic. Aside from performing a soft reset, flipping the ringer switch from ring to silent mode and vice versa can likewise offer prompt solution. Here’s you should do the:

  2. After a few seconds, flip the switch again to switch your iPhone back to ring mode.

If the switch appears to be stuck, try to remove any case from your device  to make sure nothing blocks the switch.

After removing any casing, restart your iPhone and then test to see if you can now hear sounds. Make sure that the volume is not set to a very low level. You can press the Volume Up or Volume Down button on the side of your iPhone to determine if it has something to do with the volume level. You can also manage the audio settings on your iPhone and make some necessary adjustments.
