[ZenBook UX433FA_UX433FA, Realtek ALC294, Speaker, Internal] No sound at all

[Oran Gol]

There is no sound whatsoever while the controls all seems to indicate the playback is working. The patop's internal speaker, headphones, even bluetooth is not outputting any sound. Trying to upgrade the kernel to two different versions had no effect. There simply is no sound output nor is there any indication the microphone is working either, but without sound output that's hard to confirm. There are not issues with sounds when I boot into Windows

Looks like it should be fixed with that kernel commit
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/sound/pci/hda/patch_realtek.c?id=0bea4cc8383519f78f3f74caca7bdebdfb346d3b

Hello,

it looks like the kernel you're using is not an officially supported ubuntu kernel, can you install the latest Ubuntu HWE kernel [1] and try again?
   sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

It should include the commit mentioned by Sebastien here in comment #2.

Thanks
