擦洗孙子的时间线导致以前卸载的孙子swf的声音播放，干扰当前播放的孙子swf的声音

Question

我面临的问题是什么？ 我有一个父文件。它按概述文件的名称加载子项。概述文件进一步加载许多（孙子）文件。我在父文件上有一个时间线擦除器。它可以擦除子文件和孙文件。问题是如果我加载孙子文件，卸载它。然后加载下一个孙子文件并擦除时间线，先前加载的孙子文件的声音开始播放。我怎么能阻止它？请帮助，我努力但我无法解决，我是业余的，没有正式的编程知识。感谢。

我提供了一个链接http://www.sendspace.com/filegroup/RA9RziNuDlC2MPj%2F11DoLLkW4A7ota%2B4KmmbltoalaeH%2FYEipSU22U2tlMBOBefBFc1RnhYpLCv3pRyAfFLxfA，以防有人想要查看代码。

重现错误：打开父文件。单击装甲链接，然后单击主页按钮以卸载它。现在，点击火炮链接，拖动洗涤器。

现在你将听到以前卸下的“装甲”孙子swf与该炮兵的声音一起播放的重叠声音。
