I am trying to install ubuntu 19.04 on a (new) asus zenbook UM431D. Everything works fine (wifi, touchpad,screen,...) except the audio output (and input): the audio that comes out is some kind of "underwater sound" audio changes and varies with time (same note is not always the same sound) Some noises (difficult to describe) comes out at any time even if i turn off the audio!
I haven't found similar issues on the internet. edit, i discovered that my audio card is a "alc294" (who has a lot of issues ).I appears that i need to upadate my kernel to 4.20 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784485)) but my kernel is already 5.3.0-18-generic.
What i already tried:
- start and stop pulseaudio (didn't change anything)
- sudo modprobe -v snd-hda-intel (from : Ubuntu 18.04 sound doesn't work, dummy output).
- searching for drivers (no any found)
- i tried a arch linux distro (same issue)
- ubuntu 18.04 => same issue
- a lot of other things
(i am working on live usb, but if needed i can install ubuntu even if the audio doesn't work ) my audio card is: Family 17h (Models 10h-1fh) (on lscpi)
Thanks
