一些正常的更新杀死了我的声音设备

  • 772

我是一个普通的香草pulseaudio用户。无特殊设置。

多年来一直在这款笔记本上使用具有良好音频的 kubuntu 18.04。

一两个月前，一次内核更新破坏了我的音频，所以我恢复到以前的内核，直到下一个内核再次出现。

我刚刚在我的系统上安装了一些正常的更新，音频不再工作。

我不经常重新启动 - 除非更新需要它，所以我不确定是否有问题，但直到我不得不为新内核重新启动时才出现。

我怎样才能解决这个问题？

我刚刚重新启动，我的音频不见了。设备消失了。（kubuntu 18.04 英特尔 64 位）

昨天早些时候它工作正常。

我尝试回到以前的内核。

我尝试了几个以前版本的 linux-firmware。

dmesg 显示这个

这是一大堆零，但我不知道它在工作时是什么样子。

我尝试播放 mp3，但 Amarok 说没有设备 - 回退到默认设置。

系统设置仅显示默认值。通常有一个模拟设备和一个数字 (HDMI) 设备。

我浏览了我的包裹历史记录，没有其他任何事情发生在我身上。

    • 似乎 HDMI 音频是默认设备（通常不好）：
      安装 pavucontrol（Pulseaudio 音量控制），
      在 配置选项卡中，检查“配置文件”未设置为 HDMI，而是设置为模拟。
      同样在输出设备选项卡中，单击“内部音频”附近的绿色按钮将其设为默认值。
      下一步是 alsamixer 在 Alsa 级别检查静音推子：（F6 选择声音设备）。在这里
      查看更多详细信息。
    • 编辑pulseaudio错误：尝试此命令
      mv ~/.config/pulse ~/.config/pulseold 然后重新启动
    • 如果不行，试试这个命令看看是否有进程锁定了音频设备：
      sudo fuser -v /dev/snd/*
