我无法在任何视频或 CD 中播放声音。我尝试了不同的方法来播放声音，但都没有用。我知道问题与驱动程序有关，我知道我已将其中一个驱动程序静音。我执行了命令 sudo lspci。这就是它出现的结果。

这也是我的计算机正在读取的设备列表。我播放了 CD、DVD 和 YouTube 视频……我看到了视频和图形，显示一切正常，但计算机没有输出声音。我需要做什么来修复我的声音？这些信息足以修复声音吗？

我运行了以下命令：wget -O alsa-info.shhttp://www.alsa-project.org/alsa-info.sh&& chmod +x ./alsa-info.sh && ./alsa-info.sh 这是我得到的信息的链接。我不太明白……http://www.alsa-project.org/db/?f=66f48b12f4df181d7ebf5ae5d8c5eda971ba69c0有人可以检查并告诉我为什么我的声音没有给我任何输出？

您可能想尝试 PulseAudio 音量控制。它帮助我通过 HDMI 输出响应我误静音的声音。 https://apps.ubuntu.com/cat/applications/pavucontrol/
