my alarm doesnt make sound at all

I'm sorry to hear that you're experiencing issues with your iPhone alarms. There could be several reasons why your alarms are not sounding or vibrating. Here are some troubleshooting steps you can try:

1. Make sure that the volume is turned up and not on silent or vibrate mode. You can check this by using the volume buttons on the side of your iPhone or by going to Settings > Sounds & Haptics and adjusting the volume slider.
2. Verify that you have selected a sound for your alarms. You can do this by going to the Clock app, selecting the Alarm tab, and tapping "Edit" in the top left corner of the screen. Then, tap on the alarm you want to check and make sure you have chosen a sound.
