Comment 20 for bug 1839006

The audio on your machine is Intel ASoC audio, it is not Intel HDA audio. you need to add ucm conf files specific to this machine:

git clone git://git.alsa-project.org/alsa-lib.git
cd alsa-lib
backup all contents in the folder of /usr/share/alsa/ucm/
sudo cp -rf src/conf/ucm/bytcht-es8316* /usr/share/alsa/ucm/
reboot
#check if audio works

To restore to original state:
restore all contents in the folder of /usr/share/alsa/ucm
reboot.
