How to fix sound on Asus UX534f under Ubuntu?

Question

ASUS

After installing Ubuntu 19.10 on Asus Zenbook UX534f no sound works, neither in speakers nor in headphones.
I tried to use this manual , it did not help (maybe I did not understand something).

PS In the pre-installed Win10, the sound worked. And according to ASUS support, they only have drivers for Win10.

Answer 1

What about 18.04?

Answer 2

You can try to remove all hdmi audio devices so that only one
PCH [HDA Intel PCH] remains in the system, device 0: ALC294 Analog [ALC294 Analog]
I, for example, do this on a laptop.
You need to look at what pulseaudio uses (pacmd list-sinks command)
You can cheat with the amixer command, sometimes it shows and allows you to change more sound card settings (which alsamixer for some reason does not show).
If this does not help, you need to try a newer kernel after 5.3, 5.4,5.5,5.6 have already been released
