我成功地在装有 Windows 7 的计算机上安装了 12.04。除了我尝试播放的歌曲外，其他一切都运行良好。无论是通过 VLC、Rhythmbox 还是 Audacious 播放器，我每次播放歌曲时都会听到破裂的声音，它会停止几秒钟，跳过一些部分，总的来说，这对耳朵来说是一次糟糕的体验。
在终端上，我sudo lspci -v按照“帮助”中给出的方式写入，下面是我得到的结果：

我注意到两件奇怪的事情是，我可以在 Windows 上正常播放歌曲，而且当我打开 YouTube 时，我可以观看视频而没有任何声音问题。
请帮帮我，因为我已经筋疲力尽了，我根本无法听我最喜欢的歌曲或看电影和肥皂剧。
