我需要在音乐开始后使用睡眠8秒并使用自动启动/自动播放完成，此时音乐在完成时加载，无需等待8秒。
以下代码无效：
<audio controls="controls" onloadeddata="var audioPlayer = this; setTimeout(function() { audioPlayer.play(); }, 8000)">
但目标是睡眠8秒，然后再重新启动背景音乐。
$rand_no=mt_rand (10000,1000000);
$content='<p><script>
jQuery(function() {
jQuery("#lbg_audio1_html5_'.$row["id"].$rand_no.'").audio1_html5({
