AVAudioPlayer through speakers

Question

I got the following code:

- (id)init {
    if (self = [super init]) {
        UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
        AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);    

        UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
        AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);

        [[AVAudioSession sharedInstance] setDelegate:self];
        [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];
        [[AVAudioSession sharedInstance] setActive:YES error:nil];
    }
    return self;
}

But for some reason, the sound does not want to leave the speakers, can someone see what I'm doing wrong?

The code I use for playback is:

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFilePathURL error:nil];
[player prepareToPlay];
[player setVolume:1.0];
[player play];

Answer 1

I used the AudioToolbox framework, so I initialized my audio session as follows:

AudioSessionInitialize(NULL, NULL, NULL, NULL);

Here is the rest of my code that I used to set up the audio session. I did not redefine the audio track, and I also think that this is not necessary.

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
OSStatus err = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory,
                                       sizeof(sessionCategory),
                                       &sessionCategory);
AudioSessionSetActive(TRUE);
if (err) {
    NSLog(@"AudioSessionSetProperty kAudioSessionProperty_AudioCategory failed: %d", err);
}

This is picky about how you set it up ...

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute, sizeof(audioRouteOverride), &audioRouteOverride);
