音频设置超时音乐背景

Question

I need to use a sleep for 8 seconds after the music start and finish with autostart/autoplay, right now the music loading in background when finish without wait 8 seconds.

Following code is not working:

<audio controls="controls" onloadeddata="var audioPlayer = this; setTimeout(function() { audioPlayer.play(); }, 8000)">

but the goals is sleep for 8 seconds before restart again the music in background.

  $rand_no=mt_rand (10000,1000000);
        $content='<p><script>
            jQuery(function() {
                jQuery("#lbg_audio1_html5_'.$row["id"].$rand_no.'").audio1_html5({
