那些遇到过的问题

声音在 ubuntu 20.04 上不起作用

rfc*_*rfc 5 sound nvidia pulseaudio alsa drivers

一开始声音是通过主板line out插孔工作的。前几天主板line out插孔坏了。声音非常机械化且难以理解。机箱前面板上的插孔根本没有声音（我之前没有尝试过，因为我使用的是line out背面的主板）。

计算机已使用 3 周：

我尝试了很多事情：pavucontrols、重新加载/重新启动 alsa 和pulseaudio、添加诸如 之类的行options snd-hda-intel model=auto、安装显卡驱动程序，但似乎没有任何效果。

最近的内核更新之一似乎给某些音频设备带来了问题。解决办法是修改.txt文件中的PulseAudio\xe2\x80\x99s默认采样率daemon.conf。

\n

这里\xe2\x80\x99s如何：

\n
    \n

  1. 打开终端（如果\xe2\x80\x99s尚未打开）

    \n
    2. \n

  2. 打开PulseAudio\xe2\x80\x99s配置文件：

    \n
    sudo {editor of choice} /etc/pulse/daemon.conf\n
    Run Code Online (Sandbox Code Playgroud)\n

    注意：请务必替换{editor of choice}为您选择的编辑器。

    \n
    3. \n

  3. 找到如下所示的行：

    \n
    ; default-sample-rate = 44100\n
    Run Code Online (Sandbox Code Playgroud)\n

    改成这样：

    \n
    default-sample-rate = 48000\n
    Run Code Online (Sandbox Code Playgroud)\n

    注：前面的内容;已经消失了。这个很重要。

    \n
    4. \n

  4. 保存文件并退出

    \n
    5. \n

  5. 重新启动 PulseAudio：

    \n
    systemctl --user restart pulseaudio\n
    Run Code Online (Sandbox Code Playgroud)\n
    6. \n
\n

这应该可以解决您的音频问题
