Add AudioStreamer.h file

Add this method to AudioStreamer.m 

- (void)setVolume:(float)Level
{

OSStatus errorMsg = AudioQueueSetParameter(audioQueue, kAudioQueueParam_Volume, Level);

if (errorMsg) {
    NSLog(@"AudioQueueSetParameter returned %d when setting the volume.", errorMsg);
}

}

And handle this to audiostreamclass object like

AudioStreamer *Obj = [AudioStreamer alloc] init]; 

[obj setVolume:1.0];
