AVAudio player always nil

Question

I'm not sure why my AVAudioPlayer is always nil?

#import <AVFoundation/AVFoundation.h>
@property (nonatomic) AVAudioPlayer *audioPlayer;
@synthesize audioPlayer;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Construct URL to sound file
    NSString *path = [NSString stringWithFormat:@"%@/background-music-aac.caf", [[NSBundle mainBundle] resourcePath]];
    NSURL *soundUrl = [NSURL fileURLWithPath:path];

    // Create audio player object and initialize with URL to sound
    NSError *audioError = nil;
    self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:&audioError];
    if (audioPlayer == nil) {
        NSLog(@"Error? %@", audioError);
        NSLog(@"AudioPlayer: %@", audioPlayer.description);
    }

I feel like I have this all set up right, but it doesn't work and I'm getting nil/null for the audioPlayer.

The .caf file was the problem, thanks to Brandon for the help
