I have a Teclast Tbook 10 S tablet (Intel® Atom™ x5-Z8350 CPU) and I recently installed Ubuntu 18.04.
Unfortunately I cannot get the audio device working on this devices. As far as I know the drivers are prestent but the kernel can't load them.
Here is the output of dmesg | grep 8316
:

Obviously i don't get any output nor I see the device in Settings dialog (I can only see HDMI output) or executing alsamixer
Any idea on how to solve it?
Thanks
