Our iPhone app is configured to play audio in the background, and most of the time it works well and the audio is playing.
But we had several reports from users that while the app is in the background and it IS playing audio, suddenly in the middle of playback it stops.
It seems to happen usually when the user is using apps like Facebook or WhatsApp heavily, sending and receiving many messages.
When the user returns to the app, it seems to start from the launch screen, as if it was closed, not just the audio stopped.
There seems to be no crash logs on the users phones when this happens.
What can cause this? What can we do to prevent this or what can we do to investigate when this happens? Can it be prevented entirely?
apple fixed this already.
Before the release of iOS 10.0.2, the only way to fix the bug was to unplug the EarPods and then plug them back in. Not all devices were affected, but it looks like Apple finally found the fix it promised earlier this week.

Chirp audio QR frame work is not receiving data after resuming from background (This issue is only happening on iPAD devices iOS11+)
If the app is in foreground then framework works without having any issues, but if app goes background and then resuming this happens.
Joe from Chirp here. Are you stopping the SDK when moving to the background, and starting again in the foreground?
See our example project at https://github.com/chirp/chirp-ios-examples/blob/master/Swift/Messenger/ChirpMessenger/AppDelegate.swift for an example of this.
I have just tested this on an iPad running iOS 11.4.1 and data is still received when foregrounded.
I you want the app to receive/record audio when it goes into the background state, then Background Audio must be set in the Capabilities plist. Otherwise the OS will remove the microphone connection from your app's process (to allow the new foreground app to possibly use it).
In my team's iOS app we have a bug when Siri is invoked while our app is running. Siri pops up and the waveform is shown very briefly and appears not to detect one's voice as the waveform remains very flat. Quickly thereafter it begins to list the things you can ask Siri.
We are using Xcode 6.3, tested on an iPad Mini with iOS 8.3 as well as an iPhone 5 with iOS 8.3.
The app never uses the microphone or queries any of the device audio inputs so I can't see this problem attributed to our app using the microphone directly. It does play looping ambient music and has sound effects.
Is there anything specific we should be calling an an interruption to ensure that Siri will work properly? Has anyone experienced similar issues?
This is most likely not related to your app. The iOS SDK doesn't provide a Siri API that could lead to this kind of events.
You may try to pause any ambient music/sounds effects whenever the app goes in background. (in AppDelegate.m)
Hi trying to fix a issue discovered other, the device is not playing the notification sound if it is locked. If device is unlocked the sound is played this issue happens only on iOS 8.x.
I test other apps like gmail and the same no notification sound when the device is locked
The sound is enabled from the notification center
The register for remote notification is done correctly like this
The only issue is that when the device is locked there is no notification sound even the lock screen is not lighting up like on previous versions.
Any solution to fix this ?
UPDATE:
After updating the device to iOS 8.3 seams that all iOS bugs that i notice before now are fixed , and the notification sound too, but I still what to know if there is some solution for this issue, thx.
Did you make the same noob mistake as me ? :D
I had the Do Not Disturb mode turned on and it prevented the device lock screen from waking and no sound played.
If you did, turn off Do No Disturb.
Note: the Do Not Disturb toggle can be accessed by pulling up from the bottom of the iPhone screen. It's the crescent moon icon that's next to the rotation lock button.
Along a similar vein to #Zhang, I wasn't getting any sounds because I had sound volume turned down all the way in Settings > Sounds. There is a "Ringers and Alerts" volume slider (top of the screen, in iOS 8.1 at least) that I had all the way down, and after increasing this volume slider I was able to hear the alert sounds.
Is there a way to start the audio recording when the application is in background. It doesn't looks possible if we intend to hit app store. But since we are developing on Jailbreak device I wouldn't mind using any private frameworks or hacks.
Also anybody worked out how to prevent the red status bar while record is happening in the background.
I have a very strange bug in a shipping iPad/iPhone app that I can't fix/track down.
My app plays video in a standard MPMoviePlayerController but with the interface hidden and my own buttons to play and stop.
That works fine but sometimes, after a few times of use, my app refuses to play any further video. This happens only on the iPad (in iOS 3.2.x), on the iPhone (in iOS 4.x) everything works fine all the time. Strangely enough, even after I quit my app, after I start it again it still refuses to play video. It doesn't save the video state, and it does reload the video. Only after I restart the iPad it starts working again.
If my iPad is in a "don't play video" state I can debug my app from Xcode and there isn't anything different other than the fact that the movie doesn't play but stays paused indefinitely.
The loadState property reports as MPMovieLoadStatePlayable, but the playbackState property stays MPMoviePlaybackStatePaused however many times I sent it a "play" command.
There is nothing I can do in my app (like choosing another video) to make the video work again.
The videos are 600 x 400 H.264 and are played in a view that is larger than full screen so I can show them full screen (without black bars) on the iPad without needing two different versions for iphone/ipad, because the devices have different aspect ratios.
There is plenty of RAM available (> 60 MB). Other apps that play video (iTunes/YouTube/streamToMe) play fine, but use the standard MoviePlayer interface/controls and don't of course don't play bigger than full screen.
This all makes me suspect this is an Apple bug. I haven't yet tested this in a beta version of iOS, and if so I couldn't talk about it either.
Anybody seen this behaviour? And has a possible solution? Thanks!
In this thread Ipad MPMovieplayerController video loads but automatically pauses when played it appears they solved the issue by using player.useApplicationAudioSession = NO;. Give it a try!
This is a quite common bug with MPMoviePlayerController on iPad OS 3.2.x
After a few runs of any app, the movies fail to play and if you move the scrubber you can see the frames but you can't still play the video for more than one frame at a time!
Besides you may notice a great memory consumption, due to the fact that some apps start receiving memory warnings more often than normal.
Finally you may prove this is a system problem (and not specifically an app problem) buy trying to run other apps that use the same framework, e.g. "ABC News". The issues cannot be seen with other apps that use UIWebView for instance (e.g. the ones based on You Tube videos).
The only solution is to re-boot the device. This works until next reboot.
