How to Play a sound using AVAudioPlayer when in Silent Mode in iPhone

I want to play a sound even in silent mode in iPhone.

Can it be done by using AVAudioPlayer (Without using AVAudioSession)

(For ios 3.0+)

Thanks in advance.

Actually, you can do this. It is controlled via the Audio Session and has nothing to do with AVAudioPlayer itself. Why don't you want to use AudioSession? They play nice together...

In your app, you should initialize the Audio Session, and then you can also tell indicate what kind of audio you intend to play. If you're a music player, then it sort of makes sense that the user would want to hear the audio even with the ring/silent switch enabled.

    AudioSessionInitialize (NULL, NULL, NULL, NULL);

    // Allow playback even if Ring/Silent switch is on mute
    UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
    AudioSessionSetProperty (kAudioSessionProperty_AudioCategory, 

I have an app that I do this very thing, and use AVAudioPlayer to play audio, and with the ring/silent switch enabled, I can hear the audio.

UPDATE (11/6/2013)

In the app I mentioned above, where I used the code above successfully, I have (for some time) been using the following code instead to achieve the same result:

        AVAudioSession *audioSession = [AVAudioSession sharedInstance];
        NSError *error = nil;
        BOOL result = NO;
        if ([audioSession respondsToSelector:@selector(setActive:withOptions:error:)]) {
            result = [audioSession setActive:YES withOptions:0 error:&error]; // iOS6+
        } else {
            [audioSession setActive:YES withFlags:0 error:&error]; // iOS5 and below
        if (!result && error) {
            // deal with the error

        error = nil;
        result = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&error];

        if (!result && error) {
            // deal with the error

I thought I'd post this as an alternative, in light of the most recent comment to this answer. :-)
