Note: If your device is running on an OS version older than iOS 15, go to Clock and then Bedtime.

Method 6: Disable Bluetooth and Unplug Headphones

In most cases, the alarm should ring through the device speakers regardless of any connected headphones or Bluetooth devices.

1. Swipe down from the top right corner of your screen to open the Control Centre.

2. Tap on the Bluetooth icon to toggle it off.
