Audio 使用Windows 10双启动的全新Ubuntu 18.04.5系统上没有声音

我已经有几个星期的声音问题了，它只是在我的系统上不能产生任何输出。我尝试过提交一份bug报告，但是launchpad没有给出答案，bug的重要性还没有确定，也没有分配给任何人。我以前使用过Ubuntu18.04，在声音方面没有问题

所以，我决定重新安装Ubuntu，希望这个问题能得到解决，但这并没有发生。我真的很想解决这个问题，但我不知道如何解决。我查了很多东西，试了试，但都没用

我尝试过的事情：

• 和alsamixer玩
• 玩pavucontrol和pulseaudio
• 重新安装alsa和pulseaudio
• 也可以强制重新加载
• 向

  /etc/modprobe.d/alsa base.conf添加
  选项snd hda intel dmic_detect=0

• 向

  /etc/modprobe.d/blacklist.conf添加
  黑名单snd\u soc\u skl

我请求帮助

我在下面发布相关输出：

$sudo lshw-C声音

但是仍然没有声音。

对于Pulseaudio

确保/etc/libao.conf默认为pulseaudio

默认驱动程序=脉冲

[或编辑或创建本地.libao（注意点作为第一个字符）文件 主目录（优先于系统范围内的/etc/libao.conf文件）]

确保已启用pulseaudio守护进程

systemctl——用户启用pulseaudio.service pulseaudio.socket

检查脉冲音频：

systemctl --user status pulseaudio

编辑 据报道，

语音调度器

有时会中断音频 尝试编辑

/etc/default/speech dispatcher

将

RUN=yes

更改为

RUN=no

或
如果不使用，请将其移除

另见： 它通过编辑

/etc/modprobe.d/alsa base.conf

即添加

我投票结束这个问题，因为它属于Ask Ubuntu（），谢谢！我已经用相关输出更新了我的问题。它看起来很活跃，但仍然没有声音。。。我现在该怎么办？考虑到你在这个问题上付出的努力，问起来似乎有点愚蠢，但它是否有效？如果有效，在它停止之前你是否立即更改了任何内容？我理解你为什么会想到：）我记得有一次系统更新后它坏了，但是我后来重新安装了Ubuntu系统，所以这几乎是在一个新的系统上进行的。我知道这一切看起来很奇怪，真的很奇怪。这有点不相关，但我在Ubuntu上也遇到过类似的问题，它不知从哪里冒出来，但问题是Windows启用了快速启动功能，尽管在此之前它也可以工作。你认为窗户也会打破吗？顺便说一句，谢谢你花自己的时间来帮助我。很长一段时间以来，无论我在哪里发帖，都没有人对这个问题提出过建议：）最后一次掷骰子时，请看我的编辑，记住，所有的黑客攻击都可能让事情变得更糟。在某些时候，您可能需要重新安装alsa和pulseaudio。

systemctl --user status pulseaudio
