Using AVAudio to stop playing a sound file.

- (void)viewDidLoad {
    [super viewDidLoad];

Since your sound is named "boom" it's probably not an issue for you, but stopping sounds can introduce a pretty noticeable click when the play is interrupted. I've done a couple of posts on this on our blog.

is there a way to get avaudio framework to play a listen.pls (shoutcast stream)
i know that the native quicktime player will play it on the iphone but i do not know how to make it browse to the url onload of my program

i have made a very crude iphone internet radio app using embed but no one on a iphone wants to click start when a program loads

i have a html fire embeded into a view so it can load the webpage and it works fine.

any help would be great
