如何修复 Ubuntu 18.04 上没有声音？
How to fix No sound on Ubuntu 18.04?
1) 我已经使用 Ubuntu 18.04 和 Windows 10 双启动几个月了。今天突然我的声音停止在 Ubunutu 上工作。活动 -> 声音菜单仅显示 "Dummy Output"。不过 Windows 一切都很好。
2) lsmod 的输出是：

请帮忙 - 我该如何继续？
"Dummy Sound" 在 Ubuntu 18.04 上也存在与 NVIDIA 卡类似的问题。这为我解决了：
- 以 root 身份编辑
/etc/modprobe.d/alsa-base.conf 并添加 options snd-hda-intel dmic_detect=0
- 以 root 身份编辑
/etc/modprobe.d/blacklist.conf 并在文件末尾添加 blacklist snd_soc_skl。
- 进行这些更改后，重新启动系统。
更多详细信息（和学分）：https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
我也遇到了同样的问题，尝试了@maartenor给出的解决方案，没有成功。
最终我通过将 linux 内核升级到最后的 HWE stack 恢复了声音，对我来说它是 4.15.0-106-generic 5.3.0-59-通用.
执行此操作的命令：
$ sudo apt install linux-generic-hwe-18.04
编辑文件 /etc/modprobe.d/alsa-base.conf 并添加以下行：
选项snd-hda-inteldmic_detect=0
选项snd-hda-intel模型=laptop-amic启用=是
第一行是启用扬声器，第二行是启用内置麦克风。
祝你好运！
从 Reddit 得到了这个答案。对我来说就像一个魅力！

以下步骤非常可靠。它不会永久修复暂停后音频丢失的问题，但会立即作为从暂停返回后 运行 的命令。
使用lspci获取声卡位置(0000:00:1f.3)。在我的机器上，
$ lspci
00:1f.0 ISA bridge: Intel Corporation H110 ...
00:1f.2 Memory controller: Intel ...
00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset ...
00:1f.4 SMBus: Intel Corporation 100 Series/C230 Series Chipset ...
然后，（确保以下目录存在）
$ echo 1 | sudo tee /sys/bus/pci/devices/0000:00:1f.3/remove
$ echo 1 | sudo tee /sys/bus/pci/rescan
我认为音频 driver/hardware 卡住了。所以我们删除了设备驱动程序，并重新扫描 PCI 总线以恢复音频。
试试这个..
- 打开终端
- sudo apt update && sudo apt install alsamixer
- 运行 终端中的 alsamixer。
- 按向右箭头直到转到声音选项（如果耳机转到 HEADPHONES 栏）。
- 按 M 取消静音。
- 按up/down调节音量。
- 按 Esc 退出 alsamixer。
我发现上面的答案在我的电脑上不起作用，我偶然解决了这个问题，这是我使用的脚本，与上面的答案大部分相同，但最后，你需要静音然后取消静音 auidio。如果您将脚本放入 sh 文件然后执行它，请在此处需要命令后休眠片刻，使用 sh -c 用于 root
的文件重定向
