IPhone : Can not play audio in didReceiveData method

My aim is to stream voice data to multiple devices using multipeer connnectivity.

I am using AVCaptureSession to access voice data from microphone using AVCaptureDevice type AVMediaTypeAudio.

In a custom AVCaptureAudioDataOutput class i am getting those audio data and want to stream that to all connected peers.

//sending data using Multipeer Connectivity

- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection
{

    //  NSLog(@"---A U D I O :%@",sampleBuffer);

    AudioBufferList audioBufferList;
    NSMutableData *data= [NSMutableData data];
    CMBlockBufferRef blockBuffer;
    CMSampleBufferGetAudioBufferListWithRetainedBlockBuffer(sampleBuffer, NULL, &audioBufferList, sizeof(audioBufferList), NULL, NULL, 0, &blockBuffer);

    for( int y=0; y< audioBufferList.mNumberBuffers; y++ ){
        AudioBuffer audioBuffer = audioBufferList.mBuffers[y];
        Float32 *frame = (Float32*)audioBuffer.mData;

        [data appendBytes:frame length:audioBuffer.mDataByteSize];
    }

    CFRelease(blockBuffer);
    [_session sendData:data toPeers:_session.connectedPeers withMode:MCSessionSendDataReliable error:nil];
}

In the Receiver application I am getting all nsdata in didRecievedData delegate method in MCSessionDelegate.

But I am not getting any way to play that raw NSData in Reciever application.
