I am developing an iPhone application.In this app i am using AVAudioPlayer for playing audio.
This is my code for playing the sound.
NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
resourcePath = [resourcePath stringByAppendingString:#"/sound.mp3"];
NSError* err;
player_ = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:resourcePath] error:&err];
if( err )
{
}
else
{
[player_ prepareToPlay];
[player_ play];
int playingLoops = 0;
player_.numberOfLoops = playingLoops;
}
It is woking fine on iphone devices except iPhone5.While i run the app on iPhone 5 i get following error then app crashes.
2012-11-26 09:02:28.484 test[728:1dd03] <0xb0081000> Error '!obj' trying to fetch default input device's sample rate
2012-11-26 09:02:28.484 test[728:1dd03] <0xb0081000> Error getting audio input device sample rate: '!obj'
2012-11-26 09:02:28.494 test[728:1dd03] <0xb0081000> AQMEIOManager::FindIOUnit: error '!dev'
I was also facing same problem giving the same error. when try to solve this problem i notice that there is no problem in code. we need to update media player or install flash player and it's work fine.
You have to add AVAudioPlayerDelegate to your .h file and following code to your .m file
NSString* resourcePath =[[NSBundle mainBundle]pathForResource:#"sound" ofType:#"mp3"];
NSError* err;
AVAudioPlayer *audioplayer =[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath: resourcePath] error:&err];
audioplayer.delegate=self;
if( err )
{
NSLog(#"%#",err);
}
else
{
[audioplayer prepareToPlay];
[audioplayer play];
}
This code is working for me and accept the answer if it is working.
Anbu, try below code.At my end it's working fine.
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]];
NSLog(#"File path is:->%#",[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]);
NSFileManager* manager;
manager = [NSFileManager defaultManager];
if([manager fileExistsAtPath:[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]])
{
printf("file Exists...\n\n");
}
else
printf("File not exist...\n\n");
NSError *er;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
if (audioPlayer == nil)
NSLog([er description]);
else
[audioPlayer play];
In any concern, let me know. And, also please check your console for the full path and for file exist or not.

I have an Ipad application in which i am playing a bit of sound after my operation success .it was working fine earlier.i am doing like this `
NSError *error;
NSString *bell = [[NSBundle mainBundle] pathForResource:#"sound" ofType:#"aif"];
AVAudioPlayer *av = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:bell] error:&error];
if(error) {
NSLog(#"%#",&error);
}
[av play];
but now the sound is not playing in ipad device.but in simulator it was working fine?can anybody help me?
Check if file exists:
NSError *error;
NSString *bell = [[NSBundle mainBundle] pathForResource:#"sound" ofType:#"aif"];
if([[NSFileManager defaultManager] fileExistsAtPath:bell]){
AVAudioPlayer *av = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:bell] error:&error];
if(error) {
NSLog(#"%#",&error);
}
[av play];
}
else
{
NSLog(#"File doesnot exist");
}
Note :Check phone is not set to silent mode
So I'm trying to test out the audio player on the iPhone, and I went off Troy Brant's iOS book. I have the Core Audio, Core Foundation, AudioToolbox, and AVFoundation frameworks added to my project. The error message I get is in the subject field. I read like 20 pages of Google search results before resorting to asking here! /sigh. Thanks if you can help. Here's my code, pretty much verbatim out of his book:
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"Yonah" ofType:#"caf"];
NSLog(#"%#", soundFilePath);
NSURL *fileURL = [NSURL URLWithString:soundFilePath];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
if (!error)
{
audioPlayer.delegate = self;
//audioPlayer.numberOfLoops = -1;
[audioPlayer play];
}
else
{
NSLog(#"Error loading audio clip: %#", [error localizedDescription]);
}
EDIT: Holy Shinto. I figured out what it was. I changed
NSURL *fileURL = [NSURL URLWithString:soundFilePath];
to
NSURL *fileURL = [NSURL fileURLWithPath:soundFilePath];
to the latter and I was getting a weird error, weirder than the one in the subject BUT I googled that and I changed my OS input device from my webcam to my internal microphone and guess what, it worked under the fileURLWithPath method. I'll be. Damned.
try this one- convert your url into NSdata
NSString* resourcePath = self.audioStr; //your url
NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:resourcePath]];
NSError *error = [[NSError alloc] init];
NSLog(#"url is %#",resourcePath);
audioPlayer = [[AVAudioPlayer alloc] initWithData:_objectData error:&error];
audioPlayer.numberOfLoops = 0;
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else {
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
}`
Try to read the audio file with something like this:
audioPlayer_ = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:[NSString stringWithString:soundFilePath_]]
error:&error];
I had code in a old sdk 3.0 project of mine that is not working with the new sdk. I have copied the code in a very simple project (just a uivue project and I put the sound code in onload) to make sure nothing else I did is messing it up.
I'm getting a error code -46, Domain NSOSStatusErrorDomain
code
- (void)viewDidLoad
{
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"EvilDrop-2.mp3",
[[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.volume=1.0;
audioPlayer.numberOfLoops= 0;
[audioPlayer play];
audioPlayer.delegate = self;
}
That's because you're not using -[NSString stringWithFormat: correctly. However, you don't need that method.
Try this code:
NSURL *myURL;
myURL = [[NSBundle mainBundle]
URLForResource:#"MyFile"
withExtension:#"mp3"];
I want to play mp3 file placed in resources as code is given below,
NSString *st=#"alarm_1.mp3";
NSLog(st);
NSURL* musicFile = [NSURL fileURLWithPath:st];
AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
//AVAudioPlayer *click1=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL URLWithString:#"alarm_1.mp3"]];
[click prepareToPlay];
[click play];
[click release];
but unfortunately i cant hear the sound
please help
I don't think your file name is right. Try this syntax:
NSURL *clickURL = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:clickURL error:nil];
I had a similar problem due to ARC. Instead of defining the AVAudioPlayer in the same method you are using it, you should should have an instance variable somewhere else, such as the UIViewController. This way ARC doesn't auto release this object and audio can play.
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
This is answer
I have the following to play m background music:
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/bgMusic.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
bgMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
bgMusic.numberOfLoops = -1;
bgMusic.volume = 0.1;
if (bgMusic == nil)
NSLog([error description]);
else
[bgMusic play];
But how I can I in any view, mute all sounds, not just this, any sound?
Thanks.
[[MPMusicPlayerController applicationMusicPlayer] setVolume:(use a value between 0.0 and 1.0)]
If your MPMoviePlayerController uses the application audio session, this works.
