Ubuntu 在音量较大时会失真

Ubuntu 在音量较大时会失真

我最近(大约 2 周)换到了 Ubuntu,音量超过 50% 时声音会严重失真。音量达到 50% 时,扬声器音量不足以满足日常使用。到目前为止,我尝试使用 AlsaMixer 进行调整,并替换PulseAudio 与 Pipewire并没有解决我的问题。

我该如何解决?

要查看失真的示例,这是一段 45 秒的视频o. 您可以跳至 35 (-10) 秒 / 15 (-30) 秒来听取失真效果。

注意 - 这不是扬声器/硬件的问题,因为当我使用 Windows 时它们工作得很好。

我有一台 Acer Swift 3(2018 版) -SF314-52. 终端输出sudo lspci -v
