Cordova Media Plugin - Audio stops playing after a second

Hello,

I'm building an HTML5 iOS application using the Intel XDK. I'm using the Cordova Media plugin to play .wav audio files. For some reason, the audio will only play for about a second before quickly fading out. I can't figure out why this is happening. 

I have two buttons, one that toggles recording audio and another to toggle playing the recorded audio. Here are the relevant javascript functions. 

var audioButtonDisplay = 0;
var audioRecordButtonDisplay = 0;
var audioRecord;

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    audioRecord = new Media(audioSrc, function(){}, function(){alert("audioRecord error");});
    audioRecord.setVolume(0.9);
}

function togglePlayPause() {
    var playPauseButton = $("#playPauseButton");
    if(audioButtonDisplay === 0) {
        audioButtonDisplay = 1;
        playPauseButton.removeClass("playButton");
        playPauseButton.addClass("pauseButton");
        playPauseButton.html("II");
        audioRecord.seekTo(0);
        audioRecord.play();
    }
    else if(audioButtonDisplay === 1) {
        audioButtonDisplay = 0;
        playPauseButton.removeClass("pauseButton");
        playPauseButton.addClass("playButton");
        playPauseButton.html("►");
        audioRecord.pause();
    }
}

function toggleRecording() {
    var audioRecordButton = $("#audioRecordButton");
    if(audioRecordButtonDisplay === 0) {
        audioRecordButtonDisplay = 1;
        audioRecordButton.removeClass("purple");
        audioRecordButton.addClass("red");
        audioRecordButton.html("Stop Recording");
        audioRecord.startRecord();
    }
    else if(audioRecordButtonDisplay === 1) {
        audioRecordButtonDisplay = 0;
        audioRecordButton.removeClass("red");
        audioRecordButton.addClass("purple");
        audioRecordButton.html("Start Recording");
        audioRecord.stopRecord();
    }
}

Please help me get the audio to play the full length. Thanks.
