Why is my phone not playing media or sound?

1. Check settings: On the sound settings, verify that the phone is not in mute mode or vibrate only.
2. Check cables: If you use external speakers, make sure that the cables are properly connected.
3. Restart your phone: If all sounds settings look normal, restart the phone and check again.
4. Check the media player: Make sure the media player is properly set up.
5. Check the volume buttons: Verify that you do not have any physical sound issues due to volume buttons.
