![声音问题 - 未检测到输出设备](https://linux22.com/image/1154370/%E5%A3%B0%E9%9F%B3%E9%97%AE%E9%A2%98%20-%20%E6%9C%AA%E6%A3%80%E6%B5%8B%E5%88%B0%E8%BE%93%E5%87%BA%E8%AE%BE%E5%A4%87.png)
我刚刚安装了 Ubuntu 16.04,但无法让声音正常工作 - 我已经尝试了整整十个小时。我是 Linux 新手,所以任何帮助我都会很感激。这是我的声音设置的样子,没有输出,滑块是灰色的。
扬声器是内置的,耳机通过辅助电缆连接 - 两个扬声器都没有声音。不过耳机没有硬件问题,它们连接到手机时工作正常,而且我认为内置扬声器也不会出现任何硬件问题。
我遵循了取消 AlsaMixer 主控静音等建议,但我根本看不到它:
sudo aplay -l

这似乎可能是问题所在,但我不知道下一步该怎么做:

我的笔记本是戴尔 Vostro 5568。
感谢您的任何建议!
