I tested 5.3.0-21-generic kernel on lenovo x1 carbon 7th, with the help of ucm and blacklist of snd_hda_intel and snd_soc_skl, all audio worked well.

[Fix] We need to enable SOF_HDA link and codec, then the sof driver and Legacy HDA driver work together to make the dmic work. [Test Case] Install the latest 19.10 image, build a new kernel with this patch and replace the existing kernel, After installing the blacklist package (blacklist snd_hda_intel and snd_soc_skl) and ucm package, the dmic and all output devices (speaker/hdmi) work. [Regression Risk] Low, these configs are already enabled in the oem-b-osp1 kernel for a long time, and we tested it on many lenovo/dell machines witch have or have no dmic, all worked well.
