Sometimes there's no sound on notifications after iOS9 update

I don't use WhatsApp.

I hope it works for you, but I don't have anyone muted in Whatsapp.

It might be happening with other apps too. Check if you have muted anything or anyone in any app in your iPhone. Undo it and see what happens. The point is the bug might be from some app and not from the iOS itself.

I don't use Whatsapp or any other app that has a muting ability .... so for me it's not the issue... 😟

I Noticed something a bit strange in the do not disturb section. The toggle for manual, flick it on and off a few times. And the moon icon next to battery icon. Will some times show up and some times not. I noticed the moon there this morning and it was not even set on. Phone was only on silent by using the silent switch on side of phone.

Here is the issue on iPhone 6s after upgrading to iOS9.1 https://youtu.be/CZlaiXc4AzU

I guess I didn't knock wood hard enough because it's back. Just got a call and only vibrated. Now, while typing this just watched the screen light up with an email with no sound. 😠

was just in sounds messing with the keyboard clicks on/off volume button again dont know if anyone knew this but if you tap you ringer volume then turn on / off the change with buttons then

swipe down to keyboard clicks then turn it on / off the keyboard clicks volume will sound normal again but soon as you leave sounds it goes back to you need a hearing aid to hear it

but i hit the lock sound button by accident and it sounds off apple this is by far you the worst iOS ever and to think i just got the new iphone 6s less than a month ago......

If people started taking there phones back. And saying there not fit for purpose and demanding a refund. Apple would soon pull there fingers out of there ears.

I can't believe these problems are not picked up in the beta versions.

I just sent an email off to MacRumors asking them to consider running a story.

An update on the situation. I was just sitting at my desk and my iPhone buzzed to tell me I am now on call for Marine Search and Rescue. The notification sound did not work. I decided to document this via video and upload it to YouTube. I will post the link here when I have uploaded it.

Our station had a meeting last night and decided that if Apple doesn't fix this in the next iOS update we will be dumping our iPhones for Android. I know it sounds extreme, but if someone dies because we didn't get the notification of a tasking, that will be unacceptable. We need to be able to rely on our phones in all cases, whether it be getting up for work, a job interview, picking up a child, or simply remembering to take the muffins out of the oven. If the iPhone can't be counted on to remind us of any of these important events, then there is little point in having this smart phone.

Honestly, I think the only way this is going to be fixed is if everyone having this issue bands together and does what they can to bring it to the attention of the media. Apple tends to be stubborn and dismiss these types of issues until enough people bring it to light. I am hoping my video will help with this, but I encourage you all to contact well known tech blogs and such to let them know. There is still time for Apple to look into this bug before the next update.

Again theses are simple things. Why are they not fixed in the beta stages. All apple seem to care about is trying to patch jailbreaking.

So, I have raised an issue here https://bugreport.apple.com/logon regarding this and many other problems in iOS9.1 and iPhone 6s which I have. I was contacted the other day by engineering for more info and was advised to do the following, so I strongly recommend everyone to report the bug and upload the log file to apple for a fix. They are obviously looking into it, so the more of you do it the better:

Engineering has requested the following information in order to further investigate this issue:

Please collect and attach the sysdiagnose while you're experiencing the reported issue:

1. Hold both of the volume buttons and Power button until you feel a short vibration from the iOS device.

2. Sync to iTunes on your host computer.

3. Find the file that was created on your host machine.

Note: The file the sysdiagnose folder will look similar to: "sysdiagnose_YYYY.MM.DD_HH-MM-SS-XXXX.tar.gz"

Log locations:

OS X:

~/Library/Logs/CrashReporter/MobileDevice/[Your Device Name]/DiagnosticLogs/sysdiagnose/

Note: "~/" your user folder or /Users/[your_user_name_here]/Library/Logs/... not the root level /Library/Logs/... path

Windows 8:

C:\Users\[Your User Name]\AppData\Roaming\Apple Computer\Logs\CrashReporter\MobileDevice\[Your Device Name]\DiagnosticLogs\sysdiagnose\

Note: The AppData folder is hidden by default. Click the View menu item and check the "Hidden items" checkbox and AppData will appear in the list.

Windows 7 and Vista:

C:\Users\[Your User Name]\AppData\Roaming\Apple Computer\Logs\CrashReporter\MobileDevice\[Your Device Name]\DiagnosticLogs\sysdiagnose\

Note: The AppData folder is hidden by default. Choose Folder and Search Options from the Organize menu in the file browser window, then click the View tab and change the "Hidden files and folders" option to "Show hidden files and folders".

Windows XP:

C:\Documents and Settings\[Your User Name]\Application Data\Apple Computer\Logs\CrashReporter\MobileDevice\[Your Device Name]\DiagnosticLogs\sysdiagnose\

Note: The Application Data folder is hidden by default. Choose Tools > Folder Options in the file browser window, then click the View tab and change the "Hidden files and folders" option to "Show hidden files and folders".

4. Attach the sysdiagnose file to the bug.

Thank you.

Please provide your response or results by updating your bug report and compress any bundled files (e.g. nested folders) prior to uploading.

It is pointless to just complaint in the forum without actually raising a bug report with Apple. And yes they are working on anything that is being reported, as every time I report a bug I have a reply and it is being fixed in the next patch/update.

Cheers

i solved this (now running iOS 9.2 on my iPhone 4S) by resetting the network on my iPhone.

when doing this, first make sure "Do Not Disturb" is turned off - Settings > Do Not Disturb

Then reset the network on your iPhone - Settings > General > Reset > choose Reset Network Settings.

That's all I did and it returned all my Notification sounds etc.

I had the same issue with messages not making sounds or alerting, the "do not disturb" on the person's message fixed that .. I also noticed that the "Lock Sounds" button (Under Settings/Sound) was randomly shut off for me, I clicked that back on and the sound seems to be working for now for closing my lock screen, etc. Perhaps, this "Lock Sounds" on/off button also affects messages, notifications, etc.

I Found this thread trying to repair this problem on my wife's phone that she had just upgraded.

Tried most things on here and no fix, thanks for all the hints and effort.

i stumbled upon a fix, not sure if it works for all but did work for my wife's phone.

IF you slide the screen up to where you can turn on and off bluetooth, airplane mode etc..look for something near the bottom (just above the clock and calculator). You'll see a little icon and it says AirPlaY. I clicked on that and low and there were two choices, one was iPhone other appeared to be some Bluetooth choice. I selected iPhone (the other was selected) and instantly all alert sounds came back.

Hopen the helps at least one other person.

AGain thanks fgks fkr or all the help and hints.
