On a Dell Vostro-5390, install the 18.04 (bionic).

Then enable the Pre-released updates (bionic-proposed) in the Software & Updates.
sudo apt-get update
sudo apt install linux-firmware (1.173.16)
sudo apt install linux-image-5.0.0-1042-oem-osp1 (for ubuntu 5.0 kernel, only oem-osp1 supports sof driver).
sudo apt install libasound2 (1.1.3-5ubuntu0.4)
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, headset mic and headphone 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.

Verified done on bionic (18.04).
