在最新的 KDE Neon 更新（5.24.1）（IDK 这与更新有关）之后，我的内置笔记本电脑扬声器始终不可用，并且它说我的耳机插孔始终已插入，即使我的耳机未插入插入。我尝试运行：
sudo apt-get install --reinstall alsa-base pulseaudio
sudo alsa force-reload
我已经使用 alsamixer 检查过，没有静音
但当我到达这里时：
sudo apt install alsa-tools-gui
Run hdajackretask
Parser hints > jack_detect = no
Select Apply now
我得到：
tee: /sys/class/sound/hwC0D0/reconfig: 设备或资源忙 我的结论是我的耳机插孔总是忙（已插入），有人有解决方案吗？
我的系统是 Avata Liber Intel Celeron N4000
