iPhone alarm is silent randomly

Yes, that is definitely the issue for some people. Unfortunately, not for all.

The issue for ME was that I changed the time, and inadvertently hit the AM/PM dial and changed it to PM.

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.

I had it happen again Friday when I had no calendar reminder set. I did have a 2nd alarm set for a few minutes after the first as a backup because I had to be up in a few hours and I don’t trust that I won’t accidentally hit stop instead of snooze when I’m that exhausted. Luckily I peeked at the nightstand clock early in the morning to see how much longer I had before the alarm. It was already 45 minutes after it should’ve gone off. My phone once again had the alarm screen but was dead silent. It’s possible I slept through the first one and when the second alerted it silenced both. Whatever the cause it nearly made my kids late for school and me late for work. It’s definitely a bug in what should be a pretty straightforward app. I do wish they’d get it resolved. I’ll miss having family share if I end up going back to android.

Having had the 6 and now the X, it is 100% a random bug that is just absurd.

You can literally set and alarm and test over and over - with completely random results.

Try going to alarm and setting it for 1 min later. With volume completely up, it is loud maybe 50% of time on a good day. It is possible but would need to do more useless research on whether turning phone off and back on, gives you a loud alarm at least on the first attempt. But its a crapshoot after that.

Iphone model and ios version are irrelevant (have had this happen for last 5 yrs, and like a crazy person, I continue to test it thinking I will magically get another result.

Lastly, and perhaps most bizarre, ringer can be quiet, then after a snooze or two, blare at full volume. The fact such an important feature does not work consistently is just another reason to hate this company’s products.

Yet I remain a customer - so shame on me.

I have this same problem. New iPhone XS, iOS 12. Have had iPhones since 4/4S and never had this happen. I did all the checks suggested. The only thing that fixes it is to restart the phone. Then it works for a few days but then fails again.

What seems to trigger this issue for me is playing a podcast that hasn't been completely downloaded. When it reaches the end of the file, a notification appears saying it needs to connect to the internet to download the rest. I'm asleep while this is happening, so I know nothing about it until I wake up late again and see the iPad lit up on the stop/snooze screen, but with no audible alarm.

I only use Bedtime, with no other alarms set.

Same issue for me this morning (and not the first time). Here’s a screen shot of my phone screen after I hit snooze. Normally it’s a 9 minute timer. That 9 minutes had elapsed, and was now counting up (note the negative sign in front of the timer). The phone alarm did initially sound, and I got snooze, but the snooze today was silent. Also to note: “Bedtime” do not disturb schedule is scheduled to end at 5:30am. It still was on at 7:17am.

This is a bug, not user error with the volume settings. Apple, please look into this and feel free to contact me for the logs off my phone..

Unfortunately, IOS 12 didn’t fix the issue. Mine behaves exactly the same. The only option I know of is buy an old school alarm clock. None of my kids’ phones have this issue but if yours does there seems to be no fix.

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.

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?

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?

As others have said, this does not solve the problem that was originally posted (which I have as well). This seems to be a bug. Maybe one that comes and goes with iOS versions? Yes, I have had this multiple times as well. Again, randomly. When it's happened to me, I've noticed that NO sounds appear to work (e.g. the 'click' sound it makes when locking, the keyboard sounds, etc.). Yes, the phone is NOT on silent. No, the phone is NOT connected to any headphones, speakers, bluetooth devices, etc. Yes, the sound is set on the phone to NOT be silent. The hardware silent switch is not activated. Do Not Disturb is activated (if any of that helps with debugging). Only responding to your comment because it's the first that shows up when Googling this. This appears (to me) to be related to iOS12.4.1. It never happened to me before this. I have an iPhone X if that matters. For me, restarting the phone 'fixes' the sound issue. At least for a couple of days. Same as others, the alarm IS going off (the screen shows the alarm screen with the snooze and stop buttons) but no SOUND is coming out. It's not that it's low volume. It is NO volume.
