Q: Sometimes there's no sound on notifications after iOS9 update

I've been having this problem too.  I actually noticed along the way that I could go into Sounds, and if I clicked on my text tone, it wouldn't play anything, if I clicked on others, they would work.  It was hit or miss on whether other tones would work.  This morning, I woke up, same thing, no text tone.  I went into sounds, clicked on my tone, no noise.  I turned bluetooth off, then went and clicked on my tone, and I heard it.  Turned bluetooth back on again, and I could still hear the tone.  I assume at some point today it'll stop working.  This is an iOS 9 issue, never had it before this.   Keep reporting, eventually they'll fix it.

I just called Apple Support and was told that they were not aware of this issue.....how can that be?

After telling the agent what I've tried so far she offered to swap the iPhone. Based on what I'm reading here, that probably won't resolve the issue anyway.

Has anyone had this issue resolved with new hardware?

HI,

EVery bug I have found so far and have reported have been looked up and resolved. I have reported this one as well of course but the more people are reporting it the higher they'll put it in their priority list. The link to the apple bug report website is in my previous responce. Feel free to report and hopefully in the next patch they'll fix the audio decoder bug.

Cheers

Since updating to 9.1, I haven't had the issue [knocking wood REALLY hard]. I'm hoping it stays that way!

I spoke to a couple of other people with an iPhone 6 and neither have experienced this problem at all.

• Hi, I can speek for myself only and regarding iPhone 6s only. In the report it has been specified. Hopefully it will be fixed and no other deviced are actually affected. Cheers

I need to log a bug report for not being able to log in and create a bug report. I get the following error every time, regardless of browser:

An error has occurred. For assistance accessing Apple Bug Reporter, please contact Apple Developer Program Support.

Good grief.

I'm having the same issue with bug reporting on this.  It's a frustrating going round the circle, to say the least!

Here is the bug report link again. Make sure you have screenshots/screen recordings to backup your report along with the steps to reproduce it.

Re: iOS9.1 on iPhone 6s Music app no sound and radio noise only

Thank you for this advise, it is very helpful.

I am a crew member for Marine Search and Rescue. Like others on my crew with iPhones we rely on our phones to alert us in the event of an emergency. Since iOS 9 myself and others on my crew (and my family) have had this exact issue. So far my missed notification sounds have only been for things like taking out the garbage and such. However, if these alerts fail in an emergency, it could mean the difference between someone living, or dying.

I have submitted this bug report every week since upgrading and it has yet to be fixed. I have reinstalled my phone from scratch, turned off bluetooth and tried using default sounds. So far nothing works. 

My fellow crew members have been talking and have been contemplating either attempting to downgrade to iOS 8, or perhaps ditching iPhone in favour of Android. If we can't rely on Apple devices, or Apple to recognize and fix this issue, we may have no other choice.

I called Apple Support again yesterday and asked the agent outright if she had heard of this issue - she said NO. I then asked if there was some repository or something where these issues get logged when they are reported by multiple users, she said there was but that this issue was not on that 'emerging issue' list. I told her there are multiple online threads and articles discussing this behavior, but who knows what will come of that. I am truly surprised that many users are reporting this issue, yet Apple doesn't know anything about it. I don't know if people aren't calling to report this, but I would encourage any of you who haven't called Apple Support to do so. I don't think feedback and bug reports logged on the website are going to cut it. I know it's a pain, but we gotta make some noise if we want to get any traction.

Their only suggestions for me were to restore and set up as new, or swap the device at an Apple Store. I hate dealing with the Apple Store so I went thru the process last night of setting up as new. I'll monitor for a few days and see how it goes. 

This is a REAL problem in IOS 9.01.  It has happened to both our iPhone 6's.  I overslept this morning because when the alarm went off and there was no sound.  Restarting the phone does fix it but Apple needs to fix the root cause of this problem.  It's a bug in IOS 9.01.

The BS answers don't help the folks using IOS.  We don't need to troubleshot anything except for Apple continuing to push out faulty software.

I posted earlier about my problems with this bug.  An it appears that it is a widespread problem, to the point that Forbes has an article about it:

I reported the bug and also even sent an email to Tim Cook about this, as this problem is so frustrating and it happens in  all iPhones of my family

I think I've found out what is the problem. It's bug from Whatsapp. This happens when you mute a contact in Whatsapp. If you unmute all contacts and numbers, then the problem will be fixed. I did this two days ago and till now notifications sounds are back to normal. Try it and see.

Regards.
