Playing Raw pcm audio data coming from NSStream

I am trying to play the pcm data from NSInputStream. Can anyone provide me the right approach or code to do so.

I got the Audio in StreamHasData event with following code.

uint8_t bytes[self.audioStreamReadMaxLength];
        UInt32 length = [audioStream readData:bytes maxLength:self.audioStreamReadMaxLength];

Now how can i play bytes audio data in iphone?
