Problem in playing Streaming audio in iphone

Question

Hi

I am being able to stream the audio via http request with AudioFileStream.But it has been seen that it can only plays urls like "http://202.6.74.107:8060/triplej.mp3" means with an .mp3 extension and unable to play any audio without any extension like the url "http://89.238.252.138:7000" or "http://www.tv-radio.com/station/le_mouv_mp3/le_mouv_mp3-128k.asx".I have put the code of extensions for the file type like this

AudioFileTypeID fileTypeHint = kAudioFileMP3Type;
    NSString *fileExtension = [[url path] pathExtension];
    if ([fileExtension isEqual:@"mp3"])
    {
        fileTypeHint = kAudioFileMP3Type;
    }
    else if ([fileExtension isEqual:@"wav"])
    {
        fileTypeHint = kAudioFileWAVEType;
    }
    else if ([fileExtension isEqual:@"aifc"])
    {
        fileTypeHint = kAudioFileAIFCType;
    }
    else if ([fileExtension isEqual:@"aiff"])
    {
        fileTypeHint = kAudioFileAIFFType;
    }
    else if ([fileExtension isEqual:@"m4a"])
    {
        fileTypeHint = kAudioFileM4AType;
    }
    else if ([fileExtension isEqual:@"mp4"])
    {
        fileTypeHint = kAudioFileMPEG4Type;
    }
    else if ([fileExtension isEqual:@"caf"])
    {
        fileTypeHint = kAudioFileCAFType;
    }
    else if ([fileExtension isEqual:@"aac"])
    {
        fileTypeHint = kAudioFileAAC_ADTSType;
    }

Whether I am doing it wrong or whether the streamer is not being able to play the urls like those.All the links are playing perfectly in the browser.Please help me
