Answer 1

Try 'reading' the error:

NSURL *url = [NSURL URLWithString:url1];
NSData *theData = [NSData dataWithContentsOfURL:url];
NSError *error = nil;
newPlayer = [[AVAudioPlayer alloc] initWithData:theData error:&error];
if (error == nil) {
    NSLog(@"AVAudioPlayer start playing");
    [newPlayer play];
} else {
    NSLog(@"%@", error);
}

Any "luck" ?

Include AVFoundation and AudioToolBox frameworks

Import header for that framework in .h file

    #import<AVFoundation/AVFoundation.h>
    #import<AudioToolbox/AudioToolbox.h>

Instantiate AVAudioPlayer,

    AVAudioPlayer *player

Use this code for play audio.It's working fine for me

    NSString *url1=@"http://mqm.designers99.com/Notification/mp3_files/1331551313_1919.mp3";

url1=[url1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];//Encode your url 

NSLog(@"after encoding========:%@",url1);
NSURL *url = [NSURL URLWithString:url1]; 
NSData *theData = [NSData dataWithContentsOfURL:url]; 
player = [[AVAudioPlayer alloc] initWithData:theData error:nil];
[player play];

Edit:Without encode the url you given also played well.
