@Kai-Chuan, To be safe, could you please apply the change to a LENOVO machine and test if it works or not. Dell DMIC machines depends on the soundcard's name to work while Lenovo DMIC machines depends on soundcard's long name or BIOS Rev string to work. I remember there is a LENOVO X1C7 in Taipei office, and a couple of weeks ago this machine was kept by Kaiheng. If your change could work on LENOVO X1C7, it means all LENOVO DMIC machines could work.
