 <audio controls="controls" id="warnAudio" hidden>
        <source src="~/mp3/HasNewWarn.mp3" type="audio/mpeg" />
    </audio>

 var gWarnAudioEl = document.getElementById("warnAudio");
 var isPlaying = gWarnAudioEl.currentTime > 0 && !gWarnAudioEl.paused && !gWarnAudioEl.ended
                                && gWarnAudioEl.readyState > 2;

                            if (!isPlaying) {
                                gWarnAudioEl.play();
                            }
