No sound with Ubuntu 20.04 on Asus Zenbook UX533FTC

Question

I installed Ubuntu 20.04 on my new Asus Zenbook UX533FTC-A8178T laptop coming with Windows 10, in dual boot.

No sound comes out from the speakers, or the headphones jack (while in Windows sound is ok).

I previously tried with 18.04 and it didn't work either. For several days I browsed similar "no sound questions", but it didn't work out. So now I freshly re-installed ubuntu 20.04, updated it, and installed pavucontrol, and inxi only for a fresh start.

Hoping someone can help I put some useful information below.

Thanks, Filippo

(PS I tried manjaro-gnome-19.0.2-200312-linux54.iso, while with Ubuntu 18.04 I tried different kernels: 4.19.0, 4.19.10, 4.19.43 etc etc)

Solution 1

I also have an issue with dualboot windows 10 / ubuntu 20. My issue with sound happens every time I switch from windows to ubuntu or the opposite. Haven't find a definitive solution yet, but I discovered that entering the bios menu and leaving it before starting with the other operating system allows to avoid the problem. So each time I reboot with a different operating system, I open the bios setup first, exit the bio setup, and boot with the different operating system. I have no issue when I reboot the operating system I used last...

Solution 2

Not sure about the headphone jack (don't use it) but this is what fixed the issue with no sound on the inboard speakers on my Asus Zenbook UX534FTC running Ubuntu 20.04.

https://www.linux.org/threads/asus-zenbook-15-ux534f-realtek-hd-audio-problem.27384/post-94194

Only thing I did differently was that I put the script in /etc/rc.local to make it runs at startup (personal preference).

Almost forgot, you also need to install alsa-tools if you haven't already.

Good luck!

Can it be a dualboot issue? May be removing Windows and installing Ubuntu as single-OS can solve problem?

[Filippo]

Hi, thanks for the comment. I think it may be a dual boot issue. For example when i boot to windows coming from ubuntu the clock shifts two hours back. The problem is that I need to have Windows as well. Thanks!

[Erikas]

Did you find any solution or workaround? I have UX533FTC laptop and no sound as well. No, it's not dualboot issue. I've created thread in Arch Linux forums too bbs.archlinux.org/viewtopic.php?id=255446 but seems it's missing support within the kernel, so we need to patiently wait for a upstream fix...

[Filippo]

Still no workaround, sorry!

[Arnaud Potier]

About your clock issue it's because linux and windows do not use the same time. Check howtogeek.com/323390/… it should solve your time problem (no idea for sound though)

[karel]

I've heard of that one too.

[Filippo]

Hi, this does not work for me, and I have the issue only on Linux.

[TheMan68]

Has anyone found a fix for this? Because this is exactly what happens to me and this work around fixes it

[Nicholas Stommel]

That worked for me, thanks!

[Alex M.M.]

It was exactly the fix for me too. Thank you so much! I have windows 10 + ubuntu 20.04 on asus zenbook duo
