问题摘要

  • 仅显示一个声音输出设备，可同时输出到扬声器和耳机。
    • 也就是说，Pavucontrol 中只有一个端口，并且只有一行pactl list | grep 'Active Port.*output.*'。
  • 因此，在使用耳机听音乐时不可能将扬声器静音。
  • 这两个输出在 Windows 中可以正常工作。

如果有人能帮助我解决这个问题，我将非常感激，因为我很困惑，找不到任何有用的东西。

系统

  • 硬件：联想 Thinkpad E495
    • 已更新至最新固件/BIOS。
    • 制造商没有提供较新的驱动程序。
  • Ubuntu 21.04
    • Kubuntu 变体
    • 内核 5.11
  • 全新安装；已更新apt update; apt upgrade但未安装其他软件。

到目前为止我尝试过的

卸载 linux-sound-base、alsa-base 和 alsa-utils，然后重新安装它们。

查看 AlsaMixer 中的设备；Master、PCM、Mic Boost 和 Beep 是可见的设备。Master 控制扬声器和耳机。

编辑 /etc/modprobe.d/alsa-base.conf 以添加

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=thinkpad

用 再试一次model=auto probe_mask=1。

在上述每个操作之间取下并重新插入耳机。
