Audio playback does not start

// Initialize audio player
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&err];

[audioPlayer          


        

Answer 1

Apparently AVAudioPlayer does not support streaming via. HTTP as I was trying to do, so by using AVPlayer instead, I got it working.

Answer 2

Did you initialize a AVAudioSession?

The following works fine for me. Might give you a hint of whats not working for you.

Initializing:

AVAudioSession* session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryAmbient error:nil];
[session setActive:TRUE error:nil]; 

Loading:

AVAudioPlayer* audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileUrl error:nil];
audioPlayer.numberOfLoops = 0;
[audioPlayer prepareToPlay];
audioPlayer.volume = 1.0;

Playing:

[audioPlayer play];

Update

To find the right NSRUL for fileUrl, I used this code:

NSURL* fileUrl = [NSURL fileURLWithPath:
     [[NSBundle mainBundle] pathForResource:@"MySound" ofType:@"wav"] isDirectory:NO];

And then I added MySound.wav to the project (bundle).
