解决Ubuntu 17.10声音丢失问题

我合上了笔记本电脑的盖子，当我打开它时，扬声器或耳机都没有声音。

如果我启动 Windows 并重新启动以启动 Ubuntu，也会发生这种情况。如果我关闭计算机并打开，然后启动 Ubuntu，声音就会正常工作。

我按照 askubuntu 上的说明和声音故障排除程序进行了操作，但没有任何效果。请帮忙。 在此处输入图片描述 在此处输入图片描述

如果有效请告诉我。下面的命令将通过将其附加到 /etc/modules 来加载您的 snd-hda-intel 模块，您可能需要注销/登录。 echo "snd-hda-intel" | sudo tee -a /etc/modules
