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

分类：编程问答

如何解决在使用Windows 10双启动的全新Ubuntu 18.04.5系统上没有声音

我已经在声音上遇到了一些麻烦，已经有几个星期了，它只是在我的系统上没有产生任何输出。我尝试提交错误报告，但是启动板没有答案，该错误的重要性尚未确定，并且未分配给任何人。我以前使用过Ubuntu 18.04，但声音没有问题。

因此，我决定重新安装Ubuntu，希望此问题得以解决，但这没有发生。我真的很想解决问题，但我不知道如何解决。我已经检查了很多东西并尝试了它们，但是没有任何效果...

我尝试过的事情：

  • 玩alsamixer
  • 玩pavucontrol和Pulseaudio
  • 重新安装alsa和pulseaudio
  • 进行alsa强制重装
  • 将options snd-hda-intel dmic_detect=0添加到/etc/modprobe.d/alsa-base.conf
  • 将blacklist snd_soc_skl添加到/etc/modprobe.d/blacklist.conf

我恳请帮忙。

我在下面发布相关输出：

        application.process.session_id = "2"
        application.icon_name = "firefox"
        module-stream-restore.id = "sink-input-by-application-name:Firefox"

编辑：

  • /etc/libao.conf包含脉冲作为默认驱动器（default_driver=pulse）

  • $ systemctl --user enable pulseaudio.service pulseaudio.socket不产生输出

  • $ systemctl --user status pulseaudio输出：

 pulseaudio.service - Sound Service

但是仍然没有声音。

解决方法

对于Pulseaudio

  1. 确保/etc/libao.conf的默认设置为pulseaudio

    default_driver =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（将优先于系统范围的/etc/libao.conf文件）]

  2. 确保pulseaudio守护程序已启用

    systemctl-用户启用pulseaudio.service pulseaudio.socket

检查脉冲音频：

systemctl --user status pulseaudio

修改 据报道speech-dispatcher有时会中断音频 尝试编辑/etc/default/speech-dispatcher 将RUN=yes更改为RUN=no
或
如果您不使用它，请将其删除。

另请参阅：https://askubuntu.com/questions/1218058/ubuntu-19-10-audio-driver-issue 通过编辑/etc/modprobe.d/alsa-base.conf解决了类似的问题 即添加
options snd-hda-intel dmic_detect=0
