我最近安装了更新的内核头文件
sudo apt-get install linux-headers-$(uname -r)
sudo apt autoremove
重启后，我的 wifi 和声音输入输出都消失了。这似乎是驱动程序的问题，因为当我运行：
sudo lshw -class network
Output:

对于声音输入和输出，我只看到虚拟输出。该命令pulseaudio -k && sudo alsa force-reload给我：
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).
并pacmd list-cards给出输出：
0 card(s) available.
我从英特尔网站复制了 wifi 驱动程序（https://www.intel.co.za/content/www/za/en/support/articles/000005511/network-and-io/wireless-networking.html）到我的固件文件夹，但不确定之后该做什么。
