没有声音输出 - Ubuntu 17.10 - ASUS Zenbook 13

没有声音输出 - Ubuntu 17.10 - ASUS Zenbook 13

我买了一台新的 Zenbook 13 并安装了 Ubuntu 17.10。
不幸的是,我无法获得任何声音输出(无论是内置扬声器还是耳机)。这是一个双启动系统,声音在 Windows 10 中工作正常。
已经测试了 GNOME ALSA Mixer,但没有成功。希望有人能帮忙。

答案1

现在我又有几天时间进行实验,我找到了一种适合我的情况的解决方案:当我运行 Windows 10 并重新启动计算机以切换到 Ubuntu 时,声音似乎总是消失。但是,如果我关闭计算机然后打开它并加载 Ubuntu,声音似乎可以正常工作。仍然不太明白是什么导致了这个问题。

答案2

问题是 linux alsa 驱动程序不知道如何正确处理该声卡。
