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.*'
。
- 也就是说,Pavucontrol 中只有一个端口,并且只有一行
- 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。
