iPhone alarm is silent randomly

So it's June 2019 and this issue hasn't been resolved? Is there a way to indicate the "Apple Recommended" response does not address anyone's issue?

As there is more than one issue with the same end result, it's going to be hard to present a single answer.

Apple, please fix this issue! You can't have an alarm function that randomly completely fails. People really depend on their alarm.

Apple is not reading here. If you want Apple to know you have a problem, contact customer support using the Contact Support link at the top right of every page of these forums. In addition to walking you through troubleshooting, they will log the problem. So, even if they don't manage to figure out what the issue is in your case, they will have a record. The more data points they have, the more likely they will be able to find solutions to this troubling but, fortunately, rare problem.

I use an App called " Alarm Clock for Me - Wake Up ! " (catchy name isn't it?) , instead of the Apple alarms. And I also rely on a physical alarm clock. I like the iPhone so much that this long-time alarm problem of theirs is not going to cause me to switch phones.

I had been doing that for a few years. Always setting backups a minute or so after the prior alarm. Woke up (thanks to my Echo) to several alarms showing onscreen on my phone but apparently all snoozed (the phone wasn't even where I could easily reach it), then another alarm went off with no sound at all (without me looking at front camera). Ringer volume was set to max. I have iPhone X.

Unfortunately, it's a rare problem with what appear to be multiple causes. That makes it hard to troubleshoot and hard to resolve. I suggest that everyone who has this problem contact Apple Support. Unless Apple has enough reports and enough information, it's going to be way down the priority list.

Let me add to the chorus. I have awoken to find the alarm going off, but with no sound. When that happens, the phone (iPhone X) will not play sound form ANY apps, until a restart. Well, when I put the phone down at night, to the best of my knowledge the sound is working, so at some point overnight while charging, perhaps some notification corrupts the software. It hasn't made me late to work YET, but Apple should research and fix what is a software flaw. This also seems to happen in the same breath that responses to screen swipes are delayed. I've had it happen with many apps running and also with only 1 or 2 apps running. This issue seems to go back a couple years. I am on iOS12, for the record. HELP!

"Adding to the chorus" here does nothing to get Apple's attention. As I noted before, it's a rare problem with what appear to be multiple causes. That makes it hard to troubleshoot and hard to resolve. I suggest that everyone who has this problem contact Apple Support. Unless Apple has enough reports and enough information, it's going to be way down the priority list.

So, contact Apple directly.

I have a question for everyone reading this thread. Has anyone actually tried to "Factory Reset" their iPhone ? And if so, did that actually fix this problem? When I contacted Apple Support about the silent alarm bug, that was their final recommended solution to me, but I never did try it out myself. (I use a physical alarm clock, and have been satisfied with that for now.) I think they recommended backing up photos, mail, contacts, etc., before doing the reset, but it was not something that I wanted to deal with at the time I was talking to them.

I started closing all my apps before I sleep about 3 weeks ago and so far no silent alarms.

I still use my 4th gen IPad as a back up alarm. Like many of us I have a job where being late for work is not an option.

It’s not the alarm clock that affects it. Iv has this issue a few times and the whole sound goes and you can hear music or make a phone call. You’ll be able to hear some sort of buzzing sound and once you turn your phone off and on it’s back to normal. It’s coming to a year I bought my iPhone XS Max and never had this issue with my iPhone 7 Plus.

Settings—>Face ID & Passcode (about midway down the options)

You don’t understand what is going on. iPhones can have their volume turned completely up and the ringer working perfectly. I’ve experimented with this and the problem I’ve found is if two alarms go off at the same time. Or if an alarm and a calendar notification appear at the same time. The alarm turns itself off when the calendar notification happens and if two alarms go off at the same time, the alarm becomes silent and does not ring out loud even though it has rung out loud even minutes before. The screen still shows an alarm going off but the phone will stop making any sound.

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.

This happened to me a couple years ago, except I missed an exam worth 40% of my grade and failed the class. I stopped using the alarm and eventually it seemed to resolve itself (update?). It just started happening again though and I’m still unable to find a solution. I wouldn’t take the chances and recommend getting a different app that you know works.

Today again noticed bug with sound. Again alarm was going off without sound and only vibrating. Do not disturb was off, sound level on max and alarm song was Ripples and side switch was on ringer mode. I picked up phone and heard hissing noise on both speakers. Restarted phone and then problem disapeared. Later today bug returned and I missed one call because again phone only vibrating and no sound from speakers. Then I called back and nothing heard on ear speaker, It was silent. Again did restarted phone and problem gone. What the heck Apple? I paid more than grand for xs max and this is what I get? If this will continue on iOS 12.4 or iOS 13 I will consider to move on android camp. I like my iPhone but I can’t tolerate these issues and I know that android also not perfect, but it will notificed about incoming calls with sound and will not be late to work because alarm gone without sound. Previous I did DFU restore and set phone as new and bug coming back. This is clearly a software bug not hardware deffect. Sent bug report about this to apple a few months ago.

You can certainly read back through the thread to find out.

Keep in mind that restoring a device to factory state is a diagnostic tool, not necessarily a fix in and of itself. If you restore something to factory state and it works, that's a good indicator that it's something that has been added to the phone that is causing the problem. Then, the task is to figure out what. If it doesn't resolve the problem, it indicates that there may be a hardware issue or that the may be a bug in the operating system.

Hi,

I'm glad more and more people are reporting this bug.

I've had the problem since the release of iPhone X in 2017.

As far as I know, this bug only affects the X, XR, XS and XS Max models.

This bug is also reported in several other forums.

You can't rely on the alarm clock at all and that's why I overslept once.

The error has also occurred to me once while using the timer. The iPhone didn't make any noise anymore and only a restart helped.

From time to time only the upper loudspeaker (earpiece) fails. You can't hear anything when making a phone call (see also here: https://discussions.apple.com/thread/8146714 ).

Restoring with iTunes doesn't help. The error comes back.

With my iPhone 5 and SE this bug has never occurred before.

Very very annoying.

Hi,

this indicates that the bug is not directly related to the alarm clock app. Rather, the sound playback itself is affected.

Was it also the case that you had to restart your iPhone in order to hear noises again?

Which iPhone do you have?
