Question

I’ve implemented AVAudioPlayer into my iPhone app but the audio being played is far too loud. To quieten the sound slightly, I changed the volume to 0.2f to see if it would have any effect. The volume stayed exactly the same. Here’s the code I’m using:

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/Blip.mp3", [[NSBundle mainBundle] resourcePath]]];

NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = 0;
[audioPlayer setVolume:0.2f];

if (audioPlayer == nil)
    NSLog(@"Whoopsies, there was an error with the sound!");
else
    [audioPlayer play];

Why won’t this turn the volume down?

Can somebody explain how I can?

Thanks!

Replace your code:

[audioPlayer setVolume:0.2f];

with following code:

    audioPlayer.volume = 0.2;

Hope this helps you.
