AVAudioPlayer successfully calls play method but not playing sound - ios

AVAudioPlayer successfully calls play method and is working properly in the simulator but it is not playing sound. The device has iOS 7.1.1. This is the code that I have used.
NSBundle *mainBundle = [NSBundle mainBundle];
NSString *filePath = [mainBundle pathForResource:#"miata-hn" ofType:#"wav"];
NSData *fileData = [NSData dataWithContentsOfFile:filePath];
NSError *error = nil;
/* Start the audio player */
self.playerAudio = [[AVAudioPlayer alloc] initWithData:fileData error:&error];
self.playerAudio.volume = 1;
if (error)
{
NSLog(#"error localized description %#",[error localizedDescription]);
}
if (self.playerAudio != nil)
{
/* Set the delegate and start playing */
self.playerAudio.delegate = self;
if ([self.playerAudio prepareToPlay] && [self.playerAudio play])
{
NSLog(#"player success");
}
else
{
NSLog(#"sound player failed to play audio");
}
}
else
{
/* Failed to instantiate AVAudioPlayer */
}

I got The solution. After adding this line of code the audio is audible in app.
AVAudioSession should be activated.
**
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&error];
[[AVAudioSession sharedInstance] setActive:YES error:&error];
**

Try using:
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];

Playing music with audio normalize using AVAudioPlayer

I’m trying to play a music with volume normalization, applyied by iVolume.
The music play 1 or 2 seconds and just after apply the volume normalization. Apparently the music is correctly, on native iPod player works fine.
After two days searching and testing, I can’t find any solution or tips.
I’m using AVAudioPlayer, because I need to get external audios.
Follow the music:

Piece of code:
NSError *setCategoryError = nil;
NSError *setAVError = nil;
NSString *path = [NSString stringWithFormat:#"%#/02GreenDay.m4a", [[NSBundle mainBundle] resourcePath]];
NSURL *soundUrl = [NSURL fileURLWithPath: path];
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: soundUrl error:&setAVError];
NSLog(#"Error: %#",[setAVError localizedDescription]);
AVAudioSession *session = [AVAudioSession sharedInstance];
if (![session setCategory:AVAudioSessionCategoryPlayback
error:&setCategoryError])
{
NSLog(#"%#",[setCategoryError localizedDescription]);
NSLog(#"Error AudioSession");
}
[session setActive:YES error:nil];
[_audioPlayer prepareToPlay];
[_audioPlayer play];
The _audioPlayer is a property.
Any ideas?
Thanks!

AVAudioPlayer crashing when calling stop

I am trying to run 3 audio files for a specific amount of time then stop them. I can play all 3 audio files at the same time no worries, but when I try to stop them I receive this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ViewController stopMusic:]: unrecognized selector sent to instance
This is what my code looks like to play the file:
- (void)backgroundTap {
[customerNameTextField resignFirstResponder];
[customerEmailTextField resignFirstResponder];
if ((audioPlayer) || (audioPlayer2) || (audioPlayer3)) {
NSLog(#"still playing");
} else {
[NSTimer scheduledTimerWithTimeInterval:10.0
target:self
selector:#selector(stopMusic:)
userInfo:nil
repeats:NO];
// create audio session
[[AVAudioSession sharedInstance] setDelegate: self];
NSError *setCategoryError = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: &setCategoryError];
if (setCategoryError)
NSLog(#"Error setting category! %#", setCategoryError);
// path
NSString *soundPath =[[NSBundle mainBundle] pathForResource:#"tuiSong" ofType:#"mp3"];
NSURL *soundURL = [NSURL URLWithString:soundPath];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error];
audioPlayer.numberOfLoops = 0;
[audioPlayer setVolume: 0.1];
// path
NSString *soundPath2 =[[NSBundle mainBundle] pathForResource:#"beachSong" ofType:#"mp3"];
NSURL *soundURL2 = [NSURL URLWithString:soundPath2];
NSError *error2;
audioPlayer2 = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL2 error:&error2];
audioPlayer2.numberOfLoops = 0;
[audioPlayer2 setVolume: 0.06];
// path
NSString *soundPath3 =[[NSBundle mainBundle] pathForResource:#"CicadaSong" ofType:#"mp3"];
NSURL *soundURL3 = [NSURL URLWithString:soundPath3];
NSError *error3;
audioPlayer3 = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL3 error:&error3];
audioPlayer3.numberOfLoops = 5;
[audioPlayer3 setVolume: 0.05];
// play bells
if (!audioPlayer) {
NSLog(#"localizedDescription : %#", [error localizedDescription]);
} else {
if (![audioPlayer isPlaying]) {
[audioPlayer play];
}
if (![audioPlayer2 isPlaying]) {
[audioPlayer2 play];
}
if (![audioPlayer isPlaying]) {
[audioPlayer3 play];
}
}
}
}
And then this is what I do to stop the audio.
- (void)stopMusic {
if ([audioPlayer isPlaying]) {
[audioPlayer stop];
audioPlayer = nil;
}
if ([audioPlayer2 isPlaying]) {
[audioPlayer2 stop];
audioPlayer2 = nil;
}
if ([audioPlayer3 isPlaying]) {
[audioPlayer3 stop];
audioPlayer3 = nil;
}
}
The error message is describing the problem perfectly. Your NSTimer is calling stopMusic:. But there is no method stopMusic:. There is a method stopMusic. stopMusic is not the same as stopMusic: (with a colon). You must get the name exactly right.

AVAudioPlayer not playing sounds simultaneously

I am trying to play a couple of sounds files at the same time for the AVAudioPlayer. I read a thread explaining how to do it # AVAudioPlayer Help: Playing multiple sounds simultaneously, stopping them all at once, and working around Automatic Reference Counting . It seems to be a weird issue as I when i try to only play one file at a time (when self.options.on is ON), it works, but when I try creating multiple instances (the else statements) and play them nothing plays. I checked to see if the outputfile URL is correct and it is, so what is the reason that it isn't working?
Thanks!
- (void)playTapped:(id)sender
{
if (!recorder.recording)
{
if(self.options.on)
{
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayback error:nil];
NSArray *pathComponents = [NSArray arrayWithObjects:
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],
[NSString stringWithFormat:#"sound%i.m4a",last],
nil];
NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:outputFileURL error:nil];
NSLog(#"%#",player.url);
[player setDelegate:self];
[player play];
}
else
{
// trying to play all sounds at once
for (NSString *str in self.soundsCreated){
NSLog(#"%#",str);
NSArray *pathComponents = [NSArray arrayWithObjects:
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],
[NSString stringWithFormat:#"sound%#.m4a",str],
nil];
NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:outputFileURL error:nil];
NSLog(#"%#",audioPlayer.url);
[audioPlayer prepareToPlay];
[audioPlayer setDelegate:self];
[audioPlayer play];
}
}
}
}
NOTE
I tried initializing with NSError check but i'm not getting any errors:
NSError *sessionError = nil;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:outputFileURL error:&sessionError];
if (sessionError)
{
NSLog(#"Error in audioPlayer: %#",[sessionError localizedDescription]);
}
SOLUTION
It seemed to be an issue with the initialization of my NSMutableArrays.
I changed them from:
self.soundsCreated = [[NSMutableArray alloc]init];
self.playerArray = [[NSMutableArray alloc]init];
to
self.soundsCreated = [NSMutableArray new];
self.playerArray = [NSMutableArray new];
and that fixed it
I have faced the same while played a small file:
Here is my solution (example)
- (void)dropSoundWhileRefresh
{
NSError *sessionError = nil;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&sessionError];
[[AVAudioSession sharedInstance] setActive:YES error:&sessionError];
[[AVAudioSession sharedInstance] setDelegate:self];
NSURL *musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"waterDrops" ofType:#"mp3"]];
dropSound = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
[dropSound setDelegate:self];
[dropSound setVolume:0.10];
[dropSound setNumberOfLoops:0];
[dropSound play];
}
Instead of passing error as nil try this and check if initialization is working correct.
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
if (error)
{
DebugLog(#"Error in audioPlayer: %#",[error localizedDescription]);
}

how can i play remote .mp3 file in my ios application?

I'm trying to play remote .mp3 file
but its giving the following error.
The operation couldn’t be completed. (OSStatus error -43.)
here is my code :
- (void)viewDidLoad
{
[super viewDidLoad];
isPlaying = NO;
/*
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"Dar-e-Nabi-Per" ofType:#"mp3"]];
*/
NSURL *url = [NSURL
URLWithString:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
}
else
{
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
}
}
Can anyone please guide me where i'm doing mistake
For steaming audio from a remote server, use AVPlayer instead of AVAudioPLayer.
AVPlayer Documentation
Sample Code:
- (void)playSampleSong:(NSString *)iSongName {
NSString *aSongURL = [NSString stringWithFormat:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
// NSLog(#"Song URL : %#", aSongURL);
AVPlayerItem *aPlayerItem = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:aSongURL]];
AVPlayer *anAudioStreamer = [[AVPlayer alloc] initWithPlayerItem:aPlayerItem];
[anAudioStreamer play];
// Access Current Time
NSTimeInterval aCurrentTime = CMTimeGetSeconds(anAudioStreamer.currentTime);
// Access Duration
NSTimeInterval aDuration = CMTimeGetSeconds(anAudioStreamer.currentItem.asset.duration);
}
Use this to play song from URL
NSData *songData=[NSData dataWithContentsOfURL:url];
self.player = [[AVAudioPlayer alloc] initWithData:songData error:nil];
self.player.numberOfLoops=0;
_player.delegate=self;
[_player prepareToPlay];
[_player play]

Output sound to receiver and not to speaker

My audio plays from the speaker and I want it play from the receiver (with a button).
At first I am trying to force the sound to output from the receiver. (I want to be compatible with iOS 3.2)
Here is what i have just after the [super viewDidLoad];
[[AVAudioSession sharedInstance] setDelegate: self];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error: nil];
// UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_None;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
[[AVAudioSession sharedInstance] setActive:YES error:nil];
and later when I call the play :
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:lblText.text
ofType:#"mp3"]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else {
audioPlayer.delegate = self;
}
[self playAudio];
MPVolumeView *volumeView = [[[MPVolumeView alloc] initWithFrame:[volumeSlider frame]] autorelease];
[volumeSlider removeFromSuperview];
[self.view addSubview:volumeView];
What am I doing wrong ?
Here is the answer :
The override is only applicable to the kAudioSessionCategory_PlayAndRecord category and not to AVAudioSessionCategoryPlayback.
