Part 4. How to Fix iPhone Alarm No Sound
You may found that your alarm has no sound after updating to iOS 12. It would be annoying that you waked up late and found that you have missed an important activity because your iPhone alarm is silent. In order to fix the iPhone alarm no sound issue, check the guide below.
Step 1Check the Mute and ringer volumeMake sure you have turned the Mute switch off, and confirm that the volume of your ringer is on a reasonable level.
Step 2Disable or delete the Bedtime featureIf the Bedtime feature is enabled on your iPhone, and the Wake time is set the same as your another alarm, it’s of possibility that neither of them will go off. To avoid this silent alarm conflict, you can change the time for one of them or disable the Bedtime feature if it’s not necessary.
Step 3Use only one alarm clock appIf you use a third-party alarm clock app with the default iPhone Clock app at the same time, you might run into issues. To be honest, in my point of view, the default iPhone Clock app is enough for you. So if your iPhone alarm has no sound, you can try to disable one of the alarm clock app and stick with only one at one time.
Step 4Disable Bluetooth and unplug headphonesIf your device is connected to a speaker or headphones, the alarm will play through the connected devices. So confirm your iPhone is not plugged with wired or Bluetooth headphones as well as other speakers when your alarm is silent.
Step 5Reboot your iPhoneWhenever you meet a problem with your iPhone, restarting it can solve your problem in many situations. To restart iPhone, you can hold down the power button until you see the power-off slider, or press and hold the power button and volume down button simultaneously. The method you need to use depends on your iPhone model.
