Install the 19.10 (Eoan) on a Lenovo X1C7 (the machine type dmi string is LENOVO-MFG_GO_ThinkPad-MFG_IN_GO). Enable Pre-released updates (eoan-proposed) in the Software & Updates sudo apt-get update sudo apt install linux-image-5.3.0-40-generic linux-modules-extra-5.3.0-42-generic sudo apt linux-firmware (1.183.4) sudo apt install libasound2 (1.1.9-0ubuntu1.2) blacklist snd_soc_skl and snd_hda_intel in the /etc/modprobe.d/blacklist.conf (after linux-image-5.3.0-43-generic is ready, the blacklist is not needed anymore) reboot open the gnome-sound-setting, we can see speaker from output device and Digital Microphone from input device. I can play sound to speaker and record sound from Microphone. Plug a headset, I can see headphone and headset mic. They all work well and the recording volume is fine too. Plug a hdmi monitor with audio capability, I can see the hdmi audio in the UI, then I can play sound via hdmi monitor.
