Why is the alarm on my iPhone not making sound?
I have been facing an issue with my iPhone where the alarm doesn’t make any sound when it goes off. This problem has been consistent, and I have missed several important reminders because of it. I’ve checked the volume settings and even made sure that the alarm is set correctly, but for some reason, it still remains silent. Additionally, I’ve verified that the phone isn’t on silent or Do Not Disturb mode. Despite all these checks, the alarm simply doesn’t sound. This issue is becoming quite frustrating, and I’m unsure what else could be causing this problem with my iPhone’s alarm.
