Couldn't play system sound after switching to iOS 5

Question

This is how I played a beep sound effect in iOS 4:

SystemSoundId beepOnSoundId;

CFURLRef soundUrl = CFBundleCopyResourceURL(
    CFBundleGet         


        

Answer 1

I have almost the same code and it works for me in iOS5 with a video and an audio media sessions on. If you have all the code in a function to play the sound the problem may be that the SystemSoundID object gets deallocated before the sound can be played, or the problem may be with the URL. But I guess it is the first one.

See, the following code works:

The SystemSoundID declaration is in the header of the object and the object lives long enough to play the sound.

    SystemSoundID soundID;

The AudioServicesCreateSystemSoundID is in the object initialization.

    AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                                                   pathForResource: @"sound" ofType:@"wav"]], &soundID);

Then you can use AudioServicesPlaySystemSound wherever you want inside the object.

    AudioServicesPlaySystemSound(soundID);

Try putting this pieces codes in the appropriate places and you should hear the sound.
