Called on the audio stream thread when a PCM packet is received for the stream. |data| is an array representing the raw PCM data as a floating point type, i.e. 4-byte value(s). |frames| is the number of frames in the PCM packet. |pts| is the presentation timestamp (in milliseconds since the Unix Epoch) and represents the time at which the decompressed packet should be presented to the user.
