}

Try:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error: nil];
As stated in the Apple Docs:
AVAudioSessionCategoryAmbient
For an app in which sound playback is nonprimary—that is, your app can be used successfully with the sound turned off.
This category is also appropriate for “play along” style apps, such as a virtual piano that a user plays over iPod audio. When you use this category, audio from other apps mixes with your audio. Your audio is silenced by screen locking and by the Silent switch (called the Ring/Silent switch on iPhone).
Should be what you're looking for specifically.

In my app at particular time i am alerting user with beep sound which i am playing using AVAudioPlayer.
Now i want this sound to be played even when app is in background. So i can achieve this by setting AVAudioSession category as AVAudioSessionCategoryPlayback and i also want that this sound should not stop the ipod music and i can do it with it setting AVAudioPlayer category AVAudioSessionCategoryAmbient.
But i want them together means sound should also play in background and it should also not stop the ipod music.
So how can i achieve this?
If it is not possible to play sound with AVAudioSessionCategoryAmbient category in background then any other workaround this?
Apologies if i am doing any mistake.
Thanks.
you need to add one row in your project.plist file Required background modes like bellow image and set it.
and put bellow code in to your project appdelegate didFinishLaunchingWithOptions
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
NSError *error;
BOOL success = [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&error];
if (!success) {
//Handle error
NSLog(#"%#", [error localizedDescription]);
} else {
// Yay! It worked!
}
its working for me hope its useful for you my frnd al the best.
UPDATE
You can't run AVAudioPlayer and the iPod player or MPMusicPlayer or MPMoviePlayer at the same time, without doing a bit more work. If you want easy, then use Audio Toolbox's System Sounds.
please refer this bellow link:-
iPhone AVAudioPlayer stopping background music
Please check bellow Link there are demo of Playing audio file in background. please check it
http://mobile.tutsplus.com/tutorials/iphone/ios-sdk_background-audio/
When I launch my iPhone game as soon as a sound plays the background music or podcast that is playing stops. I noticed other games allow background audio to continue to play.
How is this possible? Do I need to override a method in my App Delegate?
Place this line in your application:didFinishLaunchingWithOptions: method of your AppDelegate or in general before using the audio player.
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
According to the documentation, the AVAudioSessionCategoryAmbient category is
for an app in which sound playback is nonprimary—that is, your app can be used successfully with the sound turned off.
This category is also appropriate for “play along” style apps, such as a virtual piano that a user plays over iPod audio. When you use this category, audio from other apps mixes with your audio. Your audio is silenced by screen locking and by the Silent switch (called the Ring/Silent switch on iPhone).
If you want also to ensure that no error occurred you have to check the return value
NSError *error;
BOOL success = [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&error];
if (!success) {
//Handle error
NSLog(#"%#", [error localizedDescription]);
} else {
// Yay! It worked!
}
As a final remark, don't forget to link the AVFoundation framework to your project and import it.
#import <AVFoundation/AVFoundation.h>
I use AVAudioPlayer to play music file. It just works well when playing via headphone or speaker on iPhone body. But not smooth when playing via bluetooth. Why?
Here is my code:
AVAudioPlayer *newMusicPlayer = [[AVAudioPlayer alloc] initWithData:musicData error:&error];
if (!newMusicPlayer)
{
}
else
{
[newMusicPlayer play];
}
Special thx!
This is an apple's bug on 3GS running ios5.1.1, because "Music" is not smooth too.
I am using the following code to play a audio in iOS using **AVAudioPlayer** class.
NSString *audioPath = [[NSBundle mainBundle] pathForResource:#"myAudio" ofType:#"mp3"];
NSURL *audioURL = [[NSURL alloc] initFileURLWithPath:audioPath];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error];
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
[audioPlayer play];
This is working fine in simulator. But, i am not getting the sound output when i run it on the device. The delegate methods ofAVAudioPlayerDelegate are also being called but there is no volume output. Where am i going wrong here.... Another important aspect i'v noticed here is that, i am getting a large message in my GDB while playing the audio file on simulator. But the same thing is not happening on device... Please refer the screenshot below for GDB messages while running on the simulator.
Check if your device is on loudspeaker mode or not..
to listen the sound through Loundspeaker use this -
// set audio to loudSpeaker mode for iphone
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
or you can increase the volume of your audio file using this -
Player.volume = 10.0;
Have you tried the .caf or .wav file? might possible that .mp3 is not working on iPhone. Also check the duration of your file not greater than 30 sec.
I was so so stupid.... My volume button was turned off. That was the reason.
Really sorry for wasting your time guys... My sincere apologies.
I am trying to use iPhone OS 4.0's multitasking capability. I tried to play audio in the background with no luck. I added UIBackgroundModes property in info.plist and mentioned requires audio to play in background. Also I added the code for playing the audio.
`
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"someday" ofType:#"mp3"]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[audioPlayer play];
`. The audio starts playing once i click on button in the app. But when I shut the app it stops. How can I make it play in the background?
Thanks,
Tony
It sounds like you didn't set up your Audio Session correctly. From http://developer.apple.com/iphone/library/documentation/AudioVideo/Conceptual/MultimediaPG/UsingAudio/UsingAudio.html :
For example, when using the default audio session, audio in your application stops when the Auto-Lock period times out and the screen locks. If you want to ensure that playback continues with the screen locked, include the following lines in your application’s initialization code:
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
The AVAudioSessionCategoryPlayback category ensures that playback continues when the screen locks.
Activating the audio session puts the specified category into effect.
HI,
I think this video helps u in solving ur problem...
IN WWDC videos they have clearly explained how u can enable the back ground audio...
http://developer.apple.com/videos/wwdc/2010/
to view or download these videos u need to have a apple account...
and in that see Session 109-Adopting multitasking on iPhone OS, Part2...
Hope this will help u..
