通过运行上述命令，我注意到找到的硬件是“Intel Kabylake HDMI”
但我的音响车是英特尔彗星湖驱动程序是 snd_hda_intel

我尝试过在网上搜索修复方法
- 添加内核参数snd_hda_intel.dmic_Detect=0 通过编辑 /etc/default/grub 进入 grub 启动菜单
GRUB_CMDLINE_LINUX="snd_hda_intel.dmic_detect=0"
更新 grub 并重启
结果是没有声音
请注意，使用蓝牙耳机或 USB 耳机或 HDMI 线时声音工作正常
- 添加内核参数snd-hda-英特尔probe_mask=1与上面相同的方式
确定后固件软签名软件包已安装
这次司机换成了sof-音频-pci 我可以看到不同的播放硬件设备
