Bug Description
chtmax98090 intel HD audio device doesn't work out of the box after installing ubuntu (from 14.04 to 18.04). It shows "Dummy Output" on audio devices.
Audio options shows device and it works if I do this:
git clone https:/
cd UCM
cp -r chtmax98090/ /usr/share/
alsactl store
It would be great if there were a solution to make it works out of the box. The device (Chromebook Acer CB3-111 has it's end of life for chromeOS in July-August, so I suppose more people with this device will change OS perhaps to Ubuntu).

I still have this on the latest 20.04 dailies on an Asus C200 Chromebook (that also has the
chtmax98090 chip). Even using the Github approach as listed in the OP doesn't seem to help - it appears in Pulsemixer but I still have no sound output.
