    您需要在 GRUB 上添加一个选项。

    要编辑 grub 选项：

    sudo nano /etc/default/grub

    找到GRUB_CMDLINE_LINUX_DEFAULT并添加snd_hda_intel.dmic_detect=0到它的末尾。它看起来像这样：

    GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 snd_hda_intel.dmic_detect=0"

    然后重建 grub 菜单：

    sudo grub-mkconfig -o /boot/grub/grub.cfg

    重新启动系统后，设备应该可以工作。
