我正在尝试在（新）华硕 zenbook UM431D 上安装 ubuntu 19.04。除了音频输出（和输入）之外，一切正常（wifi、触摸板、屏幕……）：发出的音频是某种“水下声音”，音频会随时间变化（相同的音符并不总是相同的声音）即使我关闭音频，也会随时发出一些噪音（难以描述）！
我在互联网上没有发现类似的问题。编辑，我发现我的声卡是“alc294”（有很多问题）。看来我需要将内核更新到 4.20（https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784485))但是我的内核已经是5.3.0-18-generic了。
我已经尝试过的：
- 启动和停止 pulseaudio (没有改变任何东西)
- sudo modprobe -v snd-hda-intel （来自：Ubuntu 18.04 声音不起作用，虚拟输出）。
- 正在搜索驱动程序（未找到）
- 我尝试了 Arch Linux 发行版（同样的问题）
- ubuntu 18.04 => 同样的问题
- 还有很多其他的事情
（我正在使用实时 USB，但如果需要，即使音频不工作，我也可以安装 ubuntu）我的声卡是：系列 17h（型号 10h-1fh）（在 lscpi 上）
谢谢

答案1
我找到了解决方法。我安装了 ubuntu 19.04（双启动）。它没有解决问题，但是当我：
- 在 bios 中禁用快速启动
- 彻底更新了电脑
- 重启
现在它运行得非常好！
因此，华硕 zenbook UM431D 与 ubuntu 19.04 完美配合（所有功能：蓝牙、wifi、屏幕、电池、声音......）
