启动Windows 8.1后，Ubuntu 14.04中笔记本电脑扬声器没有声音

我有Dell Inspiron 15 7537。

我已经在上面安装了14.04，最初的声音没有问题。但是，就像我的以太网卡一样，期望在Linux中没有驱动程序/软件问题似乎是不现实的。

我为笔记本电脑购买了SSD，并在其上安装了Ubuntu 14.04。然后，我用gparted从笔记本电脑随附的磁盘上复制了Windows分区。

一切正常，直到我启动Windows 8.1。当我在Windows中时，声音工作正常，但是在重新启动笔记本电脑并返回到Ubuntu之后，声音停止通过笔记本电脑的内置扬声器工作。

但是我注意到，在Ubuntu中，我仍然可以使用耳机来接收声音。

从这里开始，我可以启动Windows 8.1以通过内部扬声器接收声音，但是除非使用耳机，否则我将无法再使声音在Ubuntu 14.04中再次正常工作。

我决定进行实验，因此我完全擦除了磁盘，并重新安装了Ubuntu 14.04。声音回来了！然后，我再次继续在Windows分区上进行复制。同样，在启动到Windows 8.1之后又回到Ubuntu，我的内置扬声器不再发出声音。

我尝试了最常见的解决方案，例如：

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio unity-control-center
sudo alsa force-reload

或者

pulseaudio -k

我还尝试确保alsamixer中没有任何静音。我也尝试安装脉冲音频音量控制工具。如果我正在播放歌曲，则可以看到内部扬声器的音频电平在变化，就好像它应该在播放一样。

脉冲音频音量控制工具还显示我的HDMI卡是声音设备，但它识别为关闭。

可能值得注意的是，在alsamixer中，应用程序似乎将我的PCH /输出卡识别为辅助卡，将HDMI识别为第一卡。但是，情况一直如此，因此我不确定这是问题所在。

我对这一切的设计方式不甚了解，但是据我了解，我很难收集启动到另一个操作系统如何阻止扬声器在另一个操作系统上工作的信息。

我该怎么做才能恢复系统声音，并确定为什么启动Windows会导致这种现象？我非常想使用双启动系统。

Windows 8包含一项称为“混合关闭”或“快速启动”的新功能。文章“ Windows 8混合关机/快速启动功能的工作方式”中对此过程进行了描述。基本上，在关机时，Windows会杀死所有用户进程，然后将内核休眠到磁盘。它这样做是为了加快关机和启动过程。杀死所有用户进程要比将它们休眠到磁盘快，而恢复休眠的内核要比重新启动内核快。

建议Linux用户关闭“混合关闭/快速启动”，否则他们将无法挂载NTFS文件系统（因为NTFS文件系统的当前状态未存储在NTFS分区上，而是保存在休眠的内核内存中）。从这个问题来看，它似乎也可能会干扰设备初始化-可能是通过将设备置于睡眠状态，当执行正常的引导过程时设备不会从该状态醒来。
