iPhone 4 - Alarm clock goes off, but no vibe or sound?!

Same here, and I can find very, very little about it. The few posts out there (some of which are up to 4 years old) mentioning it are usually abandoned, unanswered (like this one threatens to be). Same problem here that manicjason mentioned, where the alarm will sound once, and after hitting snooze, the alarm won't sound again but the "snooze" button will again be displayed onscreen. I'm hoping this is the same bug as simagery is having. Ha, this has caused me to oversleep two days in a row now! Luckily I'm unemployed so no one cares.

Still, this problem is very very not good. Can anyone corroborate?

The alternative is to get an app that works. Check out MultiSnooze!

Need more sleep? Need less interruptions due to your snooze alarm going off again and again? You need MultiSnooze. It's my new app that I just released for the iPhone. Take all of your snoozes right up front when your alarm goes off the first time. Simply tap the snooze button as many times as you are going to be pressing the snooze button and receive that many snooze sessions. Use your iTunes playlist to wake up and more.

I just started having this problem (I wake up REALLY late, check my phone see the "Alarm - Snooze/Off" option is showing on my screen but there is no sound) and I am wondering if you ever recieved any "fix" that worked. I am also realizing that Apple isn't addressing this issue in any of the threads that I see about the problem. Is there a way to bring it to their attention? (I am new here and am not quite sure how the forums work - if Apple is monitering them or if it is up to us to fix everything.) Thanks!

A third-party app is not the answer, because you can not close the app. If you close the app, the alarm shuts off. Pointless.

Just happened to me this morning too... i will be honest and say i snooze a few too many times... but I ended up waking up an 30 minutes after I was supposed to be at work... I immediately rolled over and grabbed my phone to see what the deal was... It was on the alarm screen, with the Press to snooze, slide to cancel/end alarm (can't remember exactly what it says) and Completely silent...

NO it wasnt a volume issue, as the alarm went off earlier the same morning and like I said, I snoozed it.

And NO I didnt sleep though it for 15 min... The girlfiend smacks me after about 5 seconds of it goiing off.. shes a light sleeper... So there is no way the both of us slept though it for 15 min straight.

And lastly.. No nothing was blocking the speaker in any way...

Its a bug and it's BS that I have to have my GF now set a backup alarm on her android so I can ensure this doesnt happen again.

This is happening to me for the last 4 or 5 days on my iPhone 4S. The alarm sets off for the first time, then I press snooze and it wont make a sound again. When I wake up I see the snooze screen but no sound... This is really a big problem for me because I'm a heavy sleeper.
So there's not a fix for this issue?

At one point I erased all of my alarms and made sure my phone was updated and it never happened again. I just made sure that I set a new alarm every night (instead of just hitting the alarm on button). I just switched to the 4S so it is a shame to hear that they still haven't resolved the issue. I wonder why Apple doesn't get involved in these dicussions - it seems there are a lot of complaints about this.

Same as titocad, and I must say I'm very disappointed. Seems like this has been a problem for a while now, and Apple is still yet to fix it. Someone in another thread suggested an app called MultiSnooze, but I for one hate installing apps for simple things like this (things that should be there in the first place).

Tilliebird, setting your alarm on every night is time consuming, and I'd often forget about it. I just have it set to wake me up at 6 am from Mon - Fri, and at 9 am over the weekends. Again, it's a simple function that should work flawlessly, no extra hassle needed.

This has started happening to me the last couple of weeks. It's happened 3 times intermittently and really screwed me today. I was 45 mins late for work. The same as others, the alarm doesn't sound and I have the snooze option showing on the screen. I never hit the snooze, I just have two alarms set about 15mins apart. The first seems to go off with sound but the second won't have sound randomly. Also I some times get an alarm that won't shut off no matter what I do. I will be back at the springboard and the alarm is still going. I have to restart my phone at that point.

Same here, it happens to me every day. I just want to throw out the window this thing, that "just don't work". It looks apple is not even willing to fix this issue.

Please apple, fix this issue. Can't afford to miss work because of this!!! I'm a snooze lover & I'm having to wake up at first alarm because of this!

It happened to me since iPhone 4 and now iPhone 5. NEVER SOLVED.

I tried different iOS. Nothing. What's going on with this? It sounds, you snooze, and 45 minutes later same thing that you guys are describing: the alarm sign with no sound.

I agree that getting an alarm app is not an option.

Now the thing got worse. I downloaded the Alarm Clock app from iHandy thinking that this would solve the issue, but not. The problem is not only happening with the iPhone Clock App. SNOOZE DOESN'T WORK WITH EXTERNAL APPS EITHER. It appears on screen but doesn't sound.

Well its seems that apple just dont care at all... iOS 6.1.3 and still no sound in my alarm... what a waste of money...
