Disable Do Not Disturb The next thing to do is to check that the Do Not Disturb mode is not enabled. If it is enabled, it can silence your notifications and calls by default. So you should disable it and do so, follow these steps: 1.
Open the Settings app. Tap Sounds & Haptics. Use your finger to move the slider all the way to the right to turn your ringer volume all the way up. If you want to use the volume buttons on the left side of your iPhone to turn up the ringer volume, make sure the switch next you Change with Buttons is turned on.
Go to Settings > Do Not Disturb and find “Activate.” It is usually set to “Automatically” by default. Change it to “Manually” to see if this sound problem will be resolved. If you have an older device, it is likely that the silent button could be damaged due to excessive use.
You might have the volume turned down. Check in Settings>Sounds & Haptics. Or, you might have Do Not Disturb enabled. Check Settings>Do Not Disturb.

If it's in Ring Mode, simply flip the switch downwards to switch to turn Silent Mode on and turns off sound on your device.
When your iPhone is connected to a Bluetooth audio device, it sends sound to the device and not to the speaker on the iPhone. Turn off Bluetooth so that sounds play from the iPhone. Adjust the volume buttons while in an app. Sometimes the sound volume in an app may be turned down too low to hear.
A dead battery in one of your components creates a gap in your home security system. Some systems will react to that by setting off an alarm, alerting you to potential problems. Other home security components may sound an alarm when the battery gets low. This is the case for some fire alarms.
