iOS sound playback volume not respecting volume change or mute

This is my current code

void playSound(NSString* myString) {

    CFBundleRef mainBundle = CFBundleGetMainBundle();
    NSString *string = myString;
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, 
                        (__bridge CFStringRef) string, CFSTR ("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);

}

It works, but it doesn't let you change the volume on the device or mute it with the mute switch. What is the simplest way to enable these features? Thanks.

Why don't you use AVFoundation? If all you want is to play simple sound effects, it would be a much better choice as it is a higher level API.

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"file" ofType:@"mp3"];
NSURL *url = [NSURL fileURLWithPath:filePath];

// Assuming audioPlayer is an ivar.
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;

if (audioPlayer == nil)
    NSLog([error description]);             
else 
    [audioPlayer play];

AVAudioPlayer should respect the volume settings of the user.
