pushAudioPacket = function pushAudioPacket(data) {
        packetQueue.push(new SampleArray(data));
    }
Pushes the given packet of audio data onto the playback queue. Unlike
other private functions within Guacamole.RawAudioPlayer, the type of the
ArrayBuffer packet of audio data here need not be specific to the type
of audio (as with SampleArray). The ArrayBuffer type provided by a
Guacamole.ArrayBufferReader, for example, is sufficient. Any necessary
conversions will be performed automatically internally.

@private
@param {ArrayBuffer} data
    A raw packet of audio data that should be pushed onto the audio
    playback queue.
