iPhone alarm is silent randomly

@kjsnow25 Thank you very much for this post. I had been struggling for hours trying to "fix" this issue on my wife's and my new 11pro's, going through 7 step and 10 step processes to no avail. I could not figure out the purpose of the Attention Aware setting, but if you (or @douglas2010) would like to try to explain it I'm all ears, but I doubt I will be turning it back on! Thanks again! We never had this problem with my 5S or her 6Plus, but it was time and we will adjust.

Lala2731, yes I was responding to a specific question asked by JS656. You are right, the "Silent Alarm" problem does still happen. I use several streaming video apps (with sound too, obviously), and some of them have no problem letting the Alarm sound interrupt them when an iPhone alarm goes off, but others seem to suppress the Alarm audio and just keep streaming their own video and audio, while Apple silently displays the alarm on the screen. I'm not too bothered by these competing sound conflicts, since I bought a physical alarm clock just to be safe. But the most annoying "Silent Alarm" problem is when there is nothing else happening on the iPhone, no apps playing, and yet the alarm just displays on screen without making any noise.

I have the same issue some mornings but what I just tested was that after 15min the alarm just stops no tone or vibration after that. I am using custom ringtones but that shouldn’t matter. I did notice while I tested it to was the sound changed to a lot lower after about 5min

It is now 2020 and this issue is still not fixed. My alarm randomly does not go off. I’ve woken up and seen it on the screen as it should be making a sound. But no. My volume is up. Not on silent. Not on DND. I have purposely checked it the night before and it still happened. I had to go and buy a small alarm clock. But seriously Apple! This is a big doozy. It MUST BE FIXED.

The Silent Alarm problem is definitely a real bug. Supposedly, it only occurs in a relatively small number of iPhones. Unless Apple has covert members reading and posting on this thread, the company does NOT monitor anything that is being said here, so this is a very ineffective place to complain about the problem. I myself have bought two small alarm clocks that work well, and I also downloaded an app called "Alarm Clock For Me" that I use on my iPhone instead of trusting the Apple alarm.

Apple needs to fix this!! It should be so easy!!

Fixing an intermittent bug (or, more likely, a couple) that affects a comparatively small number of people is one of the harder things to do. The difficulty is compounded when people post here but don't also let Apple know by calling customer support, taking the phone into an Apple Store or leaving feedback. All of those things create a record that the right people at Apple see. Posting here doesn't do that.

Yeah this has got me in trouble a few times now for being late to work.. The ringer is full volume and there is a sound choice is selected, no doubt about it. I actually have the exact same problem on my ipad - I turn my timezone to CST and set the alarm, and I wake up and see that it doesn't go off and the timezone is set to PST. So maybe related to having a weak 4g connection? Wish you guys would consider this a priority though - seems to me that the user is clearly not to blame here.

How has this happened to so many of us, and affected so many people so negatively yet nothing has been done??

The thing is, it hasn't happened to very many people. It seems to be a number of bugs that each happen to a small percentage of iPhone users. Most people probably don't even report it to Apple. Intermittent bugs that happen to only a small number of people are among the hardest to troubleshoot, even when Apple knows about them. We also don't know what Apple is doing about it. For all we know, they could be working on it very hard but just haven't figured out all of the issues.

Those of us who remember alarm clocks also remember that they failed occasionally, too.

I’m having the same problem with my alarm. It will make a sound for like a second then go silent. The screen shows that it should be alarming. Also when mine is doing this certain video apps like tik tok, Joyce Meyer, they do the same thing. They place for second or two then stop. I’ve called Apple and they were getting with their specialists and nothing ever happened. I’ve even been given a new iPhone and just recently bought the newest phone on market.

Amazon Basics has one with battery back up for $10. I have a number of things from the Amazon Basics line and they're all an excellent buy for the money.

Thank you! I just checked and nearly all my alarms’ sounds had been changed to “None” too! What a ridiculous bug, ughh.

I’m having the same problem as well. Apple needs to fix this or it’s better to use another app for alarms

My alarm often has muted sound. It’s not dependable

Thank you for solving this problem. Your solution solved the problem. I was going crazy!

I'm also having this issue. I just switched from 6S to 8 over the weekend. The alarm didn't go off yesterday and I was saved by a whining dog - 10 minutes after I normally would wake. This morning I used the Alarm Clock instead of Bedtime and the alarm went off for a second, then stopped. I wouldn't have even noticed it except I had it on vibrate too. That also stopped after a second, but it was enough to wake me. My daughter complained that hers didn't go off a few weeks ago, so I'm thinking this has to be an IOS 11 issue.

I never have my ringer on and my DND is always set for 9 p.m. - 7 a.m., but I never had a problem with the alarms before.
