最近，我的 Ubuntu 22.04 桌面版上的某些网站的声音几乎听不见。这种情况只发生在我的网站上，其他网站上没有，但在 Chrome 和 Firefox 上都会发生。
它甚至发生在 YouTube 上的不同视频中。（所以大概与编解码器有关？）
Slack 中的音频几乎听不见。Google
meet 中的音频几乎听不见。youtube
上的某些视频（但不是其他视频）几乎听不见。Spotify
中的音频是听得见的
Gnome 音频控制应用程序没有帮助。
我该如何调试这里到底发生了什么？
这是 YouTube 视频的调试信息，其中音频才不是工作：

答案1

不起作用：5.717 起作用：3.054
