AudioServicesPlaySystemSound vibration works but not sound

Question

AudioServicesPlaySystemSound doesn't do anything but AudioServicesPlayAlertSound makes the iPhone vibrate.

AudioServicesCreateSystemSoundID returns success. I'm developing on iPhone3G running iOS4.

Any ideas? Peter

Here's how I create the sound:

NSString *sndPath = [[NSBundle mainBundle] pathForResource:@"first_touch" ofType:@"wav" inDirectory:@"/"];
CFURLRef sndURL = (CFURLRef)[[NSURL alloc] initFileURLWithPath:sndPath];
int e = AudioServicesCreateSystemSoundID(sndURL, &_firstTouch);  // TODO: call 'AudioServicesDisposeSystemSoundID'

And that's who I play it:

AudioServicesPlayAlertSound(_firstTouch);

Answer 1

Showing some code helps.

At a guess, you're creating a sound, playing the sound, and then immediately deleting the sound. This doesn't work; deleting the sound causes it to stop playing.

Answer 2

I'm not deleting the sound. I added the source code.

After I rebooted both my machine and the iPhone, it started working on the simulator but not on the iPhone.

It worked once on the iPhone. I'm testing with a new project with just the create and play sound in it.
