Alienware M14x - Linux Mint 14 中没有声音 (Nadia)

我已在 Alienware M14x 上全新安装了 Linux Mint 14.1 x64。安装后一切正常。不幸的是，一段时间后声音就消失了。通过 VLC、YouTube 等播放视频时没有声音。每次我都必须重新启动电脑才能恢复声音。

以下是一些信息：

snd_hda_intel 卡总是很棘手。

尝试按照以下指南取消扬声器音量静音 http://forums.linuxmint.com/viewtopic.php?f=48&t=121099alsamixer（如果您熟悉终端/命令行， 您可以执行相同的操作）
