Why my media can't play with AVFoundation?

Question

NSString *soundFileURL=[[NSBundle mainBundle]pathForResource:@"noise" ofType:@"wma"];

self.noise=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:soundFileURL] error:nil];

[self.noise play];

then the main.m have mistake. When I use short media about 1 sec it would work.

Answer 1

Because AVFoundation can't play Windows Media audio (WMA). Convert your "noise" to a supported format, such as MP3 or AAC.
