AVAudioPlayer via 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 somehow the sound does not want to come out of the speakers, can someone see what I am doing wrong?

The code I use for playing is:

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

I used the AudioToolbox framework that's why I initialized my audio session as following:

AudioSessionInitialize(NULL, NULL, NULL, NULL);

Here's the rest of my code that I used to configure the audio session. I didn't override the audio route and I also think 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);
}

You're code for playing the sound looks correct, and there's no reason you should have to use AudioToolbox. One thing you might want to make sure of is that you are using supported audio formats. (I personally have had success with MP3 and WAV)

Also, could you share with us your code as to how you get the url to your sound file?
