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://github.com/plbossart/UCM.git
cd UCM
cp -r chtmax98090/ /usr/share/alsa/ucm/
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).
