Whenever I start an AVCaptureSession running with the microphone as an input it cancels whatever background music is currently running (iPod music for instance). If I comment out the line adding the audio input, the background audio continues.
Does anyone know of a way to record video clips with the microphone while continuing to allow background audio to play? I've looked around a lot, and can't seem to find any references to this behavior.
Thanks for any help!
Try setting kAudioSessionProperty_OverrideCategoryMixWithOthers as seen in https://stackoverflow.com/a/7426406/16572
Is the background music a looping track? -- if so you could make it a system sound and tell it to re-play when it finishes playing. The reason being you can only have tracks up to 30 seconds as a system sound.
Don't know if it helps -- but thats one approach :)
Cheers,

I had the same problem and used this in my app and it worked:
UInt32 audioRouteOverride = kAudioSessionCategory_AmbientSound;
AudioSessionSetProperty (kAudioSessionProperty_AudioCategory,sizeof (audioRouteOverride),&audioRouteOverride);
I was able to record video and audio and at the same time play a sound out of the speakers.

When playing an audio file in watchOS (using SpriteKit):
run(SKAction.playSoundFileNamed("ready.wav", waitForCompletion:false))
It will works until you background the app (says face the watch outwards) and back, then the audio file cannot be played anymore.
I have tried many workarounds, including setting UIBackgroundModes to audio, but the sound will always stop working after the app is background and back. Any solution?
PS: I think I might have found the answer: use AVAudioPlayer instead of SKAction.
You need to start HKWorkoutSession and in info.plist enable workout background processing. Don't need the audio to play in background, just continue to play once it comes back from background.
Use AVAudioPlayer instead of SKAction. This works.
Only SKAction.playSoundFileNamed has this issue.
I am trying to be able to record audio through the iPhone's microphone while simultaneously playing music from the iPod.
The recording and playback work separately, but if I try to playback from the iPod and record at the same time the recording stops.
By the way, I am not actually recording the audio to save the sound file, but merely analyzing it. It's for my app that flashes to the beat of the music you play.
Does Apple just not allow record and playback at the same time?
You should be able to do this by setting the Audio Session to AVAudioSessionCategoryPlayAndRecord. Information on this is in the Apple docs, although admittedly the Core Audio documentation is (and has always been) lacking in clarity.
AVSession Class Reference
Also, it's worth noting that AVAudioRecorder and AVAudioPlayer automatically set the session for you. You can wrestle control and set the session manually using the key I highlighted above.
the problem may be you are recording audio to the same path where the playing file is saved.
try to play an audio from a url with AVAudioPlayer and you can record with AVAudioRecorder at the same time.

Im implementing a fake call app.Im using a NSTimer for checking the time and it is working fine.The problem is when we press the sleep button,only vibration is working but ring tone is not playing.I tried this code but still ring tone is not playing.
AudioSessionSetActive(true);
// Set up audio session, to prevent iPhone from deep sleeping, while playing sounds
UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty (
kAudioSessionProperty_AudioCategory,
sizeof (sessionCategory),
&sessionCategory
);
How can i solve this issue.please help.Thanks in advance
I am sorry but I think You can not show calling screen while device locked (deep sleep). The only way is to fire local notification to wake up your application manually by user. Something like : You have fake call now. Do you want to receive ? So when user press Yes and it will open your application and you will need to handle to show calling screen in appDelegate background methods.
I played with other Fake Call apps and they are doing same. We are not allowed to do any UI Changes in background. So this is the only way to achieve your goal to display calling screen.
Hope this help.
Edit:
I am not sure why vibrate is working. Did you set below property in your info.plist file ? Just to give it try. Not sure that will solve your problem. Just give it a try once. See attache picture. Set Required Background modes to App Plays Audio.
I'm using openAL to play sounds. I have a view controller that lets users upload a video. I want to give them a 1 minute warning sound so that they know to wrap things up. I tried using a call to SoundEngine_StartEffect(warningSound); but it just doesn't play anything. Is there a work around to this?
Did you try to set mix with others?
UInt32 doSetProperty = 1;
AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(UInt32), &doSetProperty);
It is in most cases a "must have", when trying to record and play at the same time.
I have an AVAudioRecorder that captures the sound. What I want is to be able to Play(AVAudioPlayer) the recorded(AVAudioRecorder) sound as it is being recorded.
I have set up the AVAudioSession property to playandRecord... but I dont know how do I program the following sort of scenario?
Like you have your head phones on and you are walking,some one beeps at you, but u can't listen because of your headphones on, but what if your iPhone captures that beep and plays right away.
If i am recording and playing on the same file at the same time. Will that be a problem?
Any help regarding this would be anticipated.
No there is no problem in that. recording and playing on the same file at the same time
