iPhone alarm is silent randomly

Hey I’ve had the same problem and I believe I have figured out why this happens. If you have multiple alarms set and you snooze the first alarm past the time the second alarm should go off, both alarms get canceled out. I have also missed important meetings and deadlines because of the lack of sound so I feel your pain. Test this out and see if it works for you, I’ve been much better off since I don’t set more than one alarm anymore.

My alarm was also going silent after a single alert. Just started doing this after I got a replacement and figured out that it was because "Attention Aware Features" was turned on. When I turned the feature off, alarm started working as normal. I think the feature turns alarm to silent as soon as I move it or it recognizes my face ID.

To turn it off go to Settings-->Face ID and Passcode--> Attention Aware Features = off

Okay is it just alarms that aren't sounding? Or is it something else as well?

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

Yes same. I use Bedtime and before I go to sleep, I check to make sure the volume is loud enough to wake me. There have been a couple times when the alarm has gone off in the am but sound was so low, I couldn't hear and slept through. Luckily, I wake at the same time but I overslept for 20min. I'll push the volume button up and hit my alarm sound and it's almost at mute. This is starting to really **** me off. Never happened on my iPad mini 2 before, only with this iPad mini 4... and this new screen is much harder to keep clean.

I have the same problem too. I used to use the Bedtime feature but after the most recent update (iOS 10.3.3), my Bedtime alarm never rings even though my iPad ( mini generation 4) is not on mute and my headphones are not plugged in. So then i switched to the Alarm feature and that worked about 3 days until the same problem occurred. I'm pretty sure i'm not doing anything wrong. I have a feeling that this is some type glitch? Please fix this ASAP Apple, I really need these alarms!!

My audio for alarm stopped working also, about a week ago, it just stopped.

I deleted the alarms and set them up again, used different sounds, nothing works to allow sound.

Turning the mute switch off will work - but I do not want to hear all the other alerts while sleeping

Nope, that’s not it. I didn’t change a thing. The latest update has made some change that makes the alarm sound so soft it can’t be heard. Someone needs to tell Apple to Quit changing stuff that already works just fine!

I've actually watched the alarm go off but it did not vibrate NOR sound. The thing is, I have set like 5 alarms for the AM. It is weird considering that some alarms actually do sound, but one or two do not.

I've read the suggestions:

Confirmed: Do Not Disturb is NOT on

Confirmed: Not connected to any bluetooth device

Confirmed: Each alarms is set to sound

Apple PLEASE Address this issue. I’ve completely stopped using the bedtime feature as it has become so unreliable. I’d say it has completely stopped going off in the morning. My alarms will go off 3/7 days of the week. This is getting ridiculous and I have been dealing with this for months now!!

I am having this same issue. I have an alarm set for 6:00am, and one set for 6:30am. The first alarm usually works, but the second one fails randomly. I will wake up, sometimes an hour late, and see the alarm on my screen, showing that it SHOULD be making a sound, but it is silent. It is clearly a glitch in the phone. If it were operator error, the alarm wouldn't work at all. It's very frustrating, and I can no longer rely on my alarm. Apple needs to get with it, and fix this issue. People shouldn't be an hour late for work, because their alarm randomly fails.

I am so relieved to find out that I’m not going crazy!!! Yipee! I’m not the only one with this problem... This is a big Issue and I really must find a solution. Do I really need to get a different alarm clock because My IPhone can’t handle it? I have always been an Apple enthusiast, but this is a MUST FIX for apple. This has cost me dearly on several occasions.

There is nothing that can be done. None of the solutions including the one here solve the problem. This has been going on since the iphone 5 and is still present in the iphone 7, and probably the 8 as well. Apple does not know how to fix the problem.

This happened again to me this morning. I ended up missing a meeting with my senior management because my alarm did not go off. I even had two different alarms set. The volume was up, the sound was turn on, and yet nothing. This issue has got to be fixed!

My theory behind this problem is that I am the type of person to set 30 different alarms to wake up. So that being said I feel like if you are the same then it could be that if you have two alarms set close together than it can glitch out and not do the audio part of the alarm; only the visual and maybe vibrate.

Also some peoples issue might just be a dirty earphone jack.

What do you think? I tend to analize things too much.
