在Ubuntu 18.04 HP笔记本中没有声音
请注意，我已经尝试了以下两个链接中的所有解决方案：
Ubuntu 14.04中的“Dummy Output”声音
声音设置中没有检测到声卡，但声音有效
pulseaudio -k && sudo alsa force-reload无法解决问题
pacmd list-cards显示0 card(s) available.
当声音在我之前的18.04上工作正常时，我试图修改/etc/modprobe.d/alsa-base.conf以便在这个答案之后解决另一个问题。 但在我的声音停止工作后，我删除了添加的行列表，将列入黑名单的驱动程序。 这可能导致了我的问题吗？
请帮助我，我无法在电脑上长时间无声地工作
更新 ：
由于我的PC上有双启动，我启动到Windows，其中声音也不起作用，Windows疑难解答无法识别问题所以我进入设备管理器并重新安装了Realtek HD Audio Controller ，它没有解决我的问题，声音仍然没有播放，但发生的一件了不起的事情是当我重新启动回到Ubuntu 18.04时，它检测到一个内置音频
现在pacmd list-cards显示：

尽管现在已经检测到这张卡，我仍然无法听到任何声音，请帮帮忙
使用以下命令安装rhythmbox和amarok音乐包：
sudo apt install rhythmbox amarok
或者如果它们已经安装，那么：
sudo apt install --reinstall rhythmbox amarok
据我所知，这些包有更多的驱动程序。
然后重启。
我有同样的问题，没有检测到任何声音设备，所以从16到18.04更新ubuntu后根本没有声音
我搜索了一些解决方案，说实话，我尝试的是一些找到的答案汇编，所以我不确定哪一个是真正的解决方案。
我做了什么，发现声音工作是：
sudo alsa force-reload
killall pulseaudio; rm -r~ / .config / pulse / *
然后重新启动但在加载ubuntu之前，我从安装在双启动中的其他操作系统快速传递，即Windows 7，因为这是一个适用于其他朋友的解决方案，因此在再次重启后，声音又回来了。
我遇到了同样的问题，我尝试了一切，但我无法解决问题。 然后我发现它不是导致问题的驱动程序，它是我提供的密码密码。
因此，如果您已尝试过所有内容，请尝试将密钥环密码重置为空白。
- 转到系统>首选项>密码和加密密钥
- 右键单击相应的文件夹
- 单击更改密码
- 输入旧密码并将新密码留空
如果它不起作用，你已经安装了chrome远程桌面应用程序
使用Ubuntu的chrome远程桌面存在一些问题。 为所有应用程序取回系统声音，您应该从chrome和ubuntu中删除扩展程序。
运行命令apt remove chrome-remote-desktop或apt-get remove chrome-remote-desktop并重启你的ubuntu
