[ZenBook S UX391UA, Realtek ALC294, Mic, Internal] No sound at all

According to https://askubuntu.com/questions/1056909/no-sound-on-asus-zenbook-ux391ua-with-hda-intel-pch , another user have the same problem as me.

found this page looking for information for same model laptop running Manjaro, also confirmed sound working on windows 10
found another page for ALC294 codec - https://askubuntu.com/questions/986140/no-sound-output-ubuntu-17-10-asus-zenbook-13
all 3 appear to have common problem caused by windows 10 shutdown

Status changed to 'Confirmed' because the bug affects multiple users.

This also happens on Manjaro, see https://forum.manjaro.org/t/alc294-analog-audio-card-detected-but-no-sound-internaly-or-headphones/54089/16

Did somebody already find a solution or knows how to debug this properly?

I am experiencing the same problem running Ubuntu and Windows 10 on the same Zenbook model. Sound working on Windows 10 but not on Ubuntu 18.04. I have not managed to solve the problem.

Same issue for me. I have Ubuntu 18.04 on Asus UX391UA. No sound either through headphones or speakers.

I even installed Windows on an external drive, because the author of this thread (https://askubuntu.com/questions/986140/no-sound-output-ubuntu-17-10-asus-zenbook-13) assumed that a proper shutdown of Windows could solve this issue for Linux users, but it didn't help either.

BTW, can somebody confirm that this ZenBook S UX391UA on Ubuntu 18.04 runs quite hot, even while doing normal "office stuff"?

At some point the preinstalled thermald daemon even forcefully shuts down Ubuntu, preventing it from overheating. "Package temperature above threshold, cpu clock throttled" normally appears before this in the logs.

The only solution I've found is to remove the thermald package. Didn't observe any undesirable side effects so far.

Not facing any issues due to heating so far. Primarily using the laptop for coding.
It does occasionally gets heated, but then nothing that causes any problems.
I'll update if I face anything.

Also affects me (ASUS Zenbook UX931U)

Same problem for me...

Still no sound, even on Ubuntu 18.10.

I've opened another issue regarding this notebook. It's about overheating. Would be very helpful, if you could share your experience here: https://askubuntu.com/questions/1087672/unusually-hot-asus-ux391ua

I'm also having an issue with my ux391ua running MATE18.04 with no Windows 10 installed. There is sound output audible with headphones on and volume >100% but it is very distorted and crackly. 18.10 was not helpful and updating kerenel to 19 doesn't change anything.

I've tried various mixer related avenues which do nothing. I noticed that pavucontrol shows sound btw.

Asus UX430U mid-2018 edition.
Dual boot Win10/Ubuntu 18.04 LTS
Audio works fine on Windows both through laptop speakers and 3.5mm jack headphones
When booted in Ubuntu -- no sound on laptop speakers or headphones.

confirm the pavucontrol shows audio streaming.

alsamixer all outputs set to "oo".

hello
I just bought a zenbook asus S UX391UA under windows 10; I installed Ubuntu 18.10 64 bits in dual boot and I have the same problem: no sound (although it works correctly under Windows)

thank you

To add to the above: shutting down the laptop and then starting from there in Ubuntu, as suggested in one of the workarounds above, actually made the sound work

@Karen Chaltikian

Good news! Although I've tried this on my UX391UA, but without success.

Can you describe your procedure step-by-step?

I have the issue as well. I have a dual boot system with following.
Zenbook UX490UAR
Ubuntu 18.04.1
Windows 10

I think this is due to windows not properly shutting down and holding on to a hardware device, although not sure how. Managed to resolve by a full shutdown. i.e. go to shutdown on the windows start menu and hold shift while pressing restart. A screen will appear where you can select to shutdown.

After the restart and logging into ubuntu, sound works .
For the volume control related bug, there was a guide here : https://askubuntu.com/questions/906303/volume-control-on-asus-zenbook-3

Can somebody confirm that the above mentioned procedure also works with an UX391UA.

It does NOT work on my UX391UA.

The above procedure does not work on my UX391UA either :(

I have same issue on new Asus ZenBook 14 UX433FA (ALC294) on Ubuntu 10.04.1 (NO dual boot).

Tried the 4.19.2 kernel and nothing changed.

Looking forward to some sort of fix/workaround!

Same on Asus Zenbook UX533 with Realtek ALC294. No sound on Kubuntu 18.10 (4.18.0-11-generic) - speakers or headphones. Dual boot with Windows 10. Windows 10 sounds work fine.

Interestingly, if I put the sound device into power save mode and wait a few seconds before playing a sound, I can actually hear it perffectly clearly, but after repeating the playing of the sound a few times, it distorts then disappears:

  sudo -i
  echo 10 >/sys/module/snd_hda_intel/parameters/power_save
  sleep 10
  aplay /usr/share/sounds/alsa/Front_Center.wav

Seems related to https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1742852

Guys please keep this ticket for Zenbook S UX391UA nad ALC294.
UX533 is different issue. This not make sense. I've got 3 other Asus laptops, where sound worked perfectly on Linux.

Rebooting through Windows 10 or setting card in power_save does not work on UX391UA.
I bought external usb-c soundcard and now I am using it with headphones.

I think that without support from Realtek (for example Kailang Yang <email address hidden> https://www.systutorials.com/linux-kernels/84502/alsa-hda-realtek-new-codecs-support-for-alc234-alc274-alc294-linux-4-4-12/), Kernel Alsa team, Canonical team or Asus there will be no changes.
I've tried to contact all of them but without any results.

Hi Pawel,

You may be right, but I think the common thread in all the laptops exhibiting this problem is the ALC294. Does the power save trick mentioned in my comment work for you at all?

Cheers,
Craig

I have the pavucontrol showing audio but no sound is coming out of the spakers.

ACL294 on Asus Zenbook UX433FA-DH74

Same problem with Asus Zenbook UX533FD.

Also, can someone please specify the windows shutdown method?
"i.e. go to shutdown on the windows start menu and hold shift while pressing restart. A screen will appear where you can select to shutdown." This doesn't work.

I am dual booting Win10 and Ubuntu 18.04.

I've tried everything. Nothing works. I originally booted into windows once and then installed linux over it. I did not power off I only did a reboot, some people are saying powering off from windows fixes sound on linux, which makes me think its some bios setting, but I don't see anything for sound settings in bios.

I no longer have windows so I can't boot into it.

I have the same issue on new Asus ZenBook 14 UX433FA (ALC294) on Ubuntu 2018.10 with Realtek ALC294.

The only workaround that I have found till now is using a bluetooth headset. It works perfectly well.

Yes, I can confirm that bluetooth works well, but I hope we can find a way to use internal sound, it's a good quality speaker for a small laptop :)

Hello,
sorry for my poor english, I am french.

A had exactly the same issue with a ASUS Zenbook UX433, and I fund a solution.

The issue comes from the Kernel part of the Alsa drivers.

Daniel Drake and Jian-Hong Pan provided a patch in the alsa mailing list to fix this issue for UX533/UX433 laptop (and maybe other Asus models) :
http://mailman.alsa-project.org/pipermail/alsa-devel/2018-December/142572.html

This patch is not in the current kernel, nor in 4.20rc tree as far I can see.
Fortunatly, you can find a patched version of the files in :
https://github.com/endlessm/linux/tree/master/sound
(A nice, easy to use linux distro)

What I did :
- clone official Kernel source repo (4.19-7 in my case)
- clone endless Os repo
- Copy the "sound" folder from endless tree to official kernel tree.
- Compile the "no more official" Kernel.
(I followed this tuto : https://wiki.archlinux.org/index.php/Kernel/Traditional_compilation because I use Manjaro, based on Arch) You have to find an appropriate tuto for Ubuntu. It was the firt time I compile a kernel.)
- Use this kernel : the sound work perfectly.

Note : I'm absolutly not a linux expert, it maybe exists a better way to use the patch than recompile the kernel.

Hi,

ALC294 works but you will have to recompile the kernel :/

A patched was made that you can find at
http://mailman.alsa-project.org/pipermail/alsa-devel/2018-December/142689.html

Be carefull there are 3 mails containing differents patches of the same file sound/pci/hda/patch_realtek.c

Personnally I have a ASUS UX433 laptop and I applied this patch on the linux-4.19.8.tar.xz kernel with a Debian distro.
Once done all works ok.

It should works also on a ASUS UX533.

Hope this helps.

Mohamed.

I'm using Ubuntu 18.04. Does anyone know if its possible to apply this patch? I would need idiot proof instructions.

I tried installing kernel 4.20-rc5 and sound speakers (built in) still don't work.

https://www.reddit.com/r/linuxquestions/comments/a4qbid/i_need_to_install_kernel_420rc/ebgtdbv

These are the instructions I used.

@sojusnik maybe this will help https://askubuntu.com/questions/1056909/no-sound-on-asus-zenbook-ux391ua-with-hda-intel-pch/1058122

Thanks Pawel!

Can confirm that installing kernel 5.0-rc1 using UKUU that sound from the speakers and earphones now work on my Zenbook UX391UA.

Confirm solved for kernel 4.20 via Ukuu for Asus Zenbook ux433f

Hello guys,

I followed your discussion to try to solve my problem. Now sound works in my PC, but I've got some other problems that came with.

My PC is an Asus UX333FN, and I'm currently running on Ubuntu 18.04 with kernel 4.20. It came with 4.15.0.29.31 originally.

When following the steps to install new kernels, above 4.18, I always get these messages :

W: Possible missing firmware /lib/firmware/nvidia/gv100/sec2/sig.bin for module nouveau

W: Possible missing firmware /lib/firmware/nvidia/gv100/acr/bl.bin for module nouveau
(This time I was trying to install 4.18 for example)

As I said, sound works, but my problem now is apparently the NVIDIA Card (it has a Geforce MX150). Sometimes my screen and my mouse freeze, and I also get something like in the attached picture. I also need to press two times the Fn keys for it to start working, which didn't happen with the other kernel.

Has someone faced the same problem?

Thank you a lot

Confirming that install 4.19.10 via ukuu as mentioned by Craig in comment #78 worked for me on zenbook ux533FD with no windows install.

I encounter the exact same problems of Thales Loiola Raveli on an ASUS 14 UX433FN with Linux Mint 19.1 Cinnamon.

When will the patch be added to a Linux Mint-supported kernel version? Please please please, it's hard to have a brand-new but mute PC :/

The problem can been solved by updating to the newest 4.19.x kernel. I am a Ubuntu user with Asus UX433FA. After a few testing, I can confirm that newer kernel 4.19.17 currently available in kernel.org is the solution (I tried out 4.19.8 as well but I experienced something else so I decided to use 4.19.17, which, by default, accepts the changes suggested by Jian-Hong).

However, I am using a dual boot system. There is a minor problem that bugs me: even if I turned off the fast boosting in BIOS, if I boot into Windows then restart and try to boot into Ubuntu, the sound will distort and disappear eventually. The solution would be completely shutdown Windows every time you want to switch between the OS. Hope this could be solved in the future.

A good thing though, is after installing the new kernel, the original 4.15.x kernel that ships with Ubuntu 18.04 can also output sound properly !!!

But, I have always got the feeling that the sound quality on Ubuntu is not as good as that of Windows. I might be over-sensitive tho.

@Thales Loiola Raveli

Try to blacklist the nouveau; go to the software updates -> additional driver to look for nvidia driver. I am fortunate that I did not get the mx150 model.

I confirm that install 4.19.10 via ukuu worked for me on zenbook ux533FD with windows 10 dual boot!

Now I can play PC game with my windows 10, and develop on my ubuntu 18.04!

Thank you all very much!

You guys are the best!

I also want to confirm that the sound has come back when I upgraded the kernel to 4.19.18. I am using Mint 19.1 and by default it didn't work.

Warning! I first upgraded to 4.20.5 but it didn't work. I switched to the 4.19 and it magically started to work!

And on a side note it works better than the stock windows version. The sound card was making weird static noises when used on Windows 10.

Hey All. I run into troubles with sound also on my Asus UX331UAL (EG022T) laptop with ALC294 sound card. I run Kubuntu 18.04.
I confirmed that after updating kernel to v4.19.19 Sound works well. Updated only kernel without any patches. Updated using Ukuu app. And it is not depending form method of shutdown windows OS (shutdown or restart).
Thanks this topic)

PS: I also run into other troubles. When laptop in sleep mode when running Kubuntu battery is not charging (battery led not lighting). When I trying to charge laptop when Kubuntu work normally, the battery starts charging (battery led lighting), but it never finishes charging and led always lighting with orange. When I shutting down my laptop battery charging in normal mode. Also, all works perfectly in Windows.
Did the anyone run into such troubles? And I will appreciate if anyone can forward me to the solution for this issue.

Small Update. Yes, sometimes when I work on Windows and reboot to Kubuntu sound card stop working.
When I load back to Windows and next shutdown it. And after that sound card begins work correctly.

I have the issue that Maksym is talking about. Indeed using 4.19.18 "fixed" the problem but it seems to be fixed somehow randomly. When I restart the laptop and enter my paassword, Linux Mint tries to play an intro chime but it gets cut off at the middle or at the end. I have to restart, login and it may or maynot fix the issue. After few restarts it starts working permanently for the duration of the session but this is not a real solution, isn't it? If someone is aware how to fix this issue please raise your voice!

@avreon Keep in mind there is two different fixes to the kernel depending on your hardware :
- Fix for UX333, UX433, UX533 and some others starting from 4.19.10
- Fix for UX391UA and some others starting from kernel 5.0-rc1

Quick question, I have exactly the same problem but with one small difference. I have Asus Q325UA which is pretty much the black version of UX391UA as far as I know. lshw gives out the following information

system Q325UAR
bus Q325UAR

My concern is that since the system reports a different model, it will require yet another different line to be added to the patch. Can somebody shed some light if that model needs to be added separately or will the UX391UA fix the problem on QA325UA as well?

Also, how should I go about submitting a request for the QA325UA if needed?

Thanks!

confirmed my sound problem was solved using
-Linux Kernel 4.19.10
on my
-aus zenbook ux533fd
-dual boot windows 10 and ubuntu 16.04

by following the next steps:

1. install Ukuu

sudo add-apt-repository ppa:teejee2008/ppa

sudo apt-get update

sudo apt-get install ukuu

2. install kernel 4.19.10

sudo ukuu --install v4.19.10

3.restart(reboot)->select "advanced options" -> select kernel version 4.19.10

for more questions, simply: <email address hidden>

thanks the commends upon, especially #78 #96

thanks all !

So I switched to Linux Kernel 5 since RC-5 and I was switching to the latest version ever since a new one is released. It seems that the 5 branch has fixed the issue for good. I am on 5.0.1 and have no issue with output. *fingers crossed*

However I do have an issue with the input. Cannot recognize my internal microphone. Not a big issue as I don't speak that much or I can use different devices for that communication but the mic is the last bit that is not working on that "damn" Asus Zenbook.

[Edited] (Didnt find how to edit a post)

Confirmed kernel 4.19.17 solved my problem.
Notebook Model: Asus Zenbook UX433FN
Ubuntu 18.10.
Dual Boot with Windows 10.

I changed the kernel with the visual interface of ukuu, easy and simple.
You just select the version, install, and then reboot. In the GRUB menu, select Advanced Options for Ubuntu, and select the desired kernel version.
If you have an Nvidia card it's possible that ukuu gets stuck in "setting up linux-headers" while installing the kernel version. Only thing you have to do to solve this is Disable Secure Boot from the BIOS.

Thanks to all in this thread, saved my life :D

@VanVan

Just updated to kernel 5.0 and the sound on my model ( Asus Q325UAR / dual boot ) does NOT work.
How/where can I submit a report so that the model is included in the list for the fix?

As far as I am aware the Q325UAR hardware is exactly the same as UX391UA but the model was targeted at a different retailer.

Thanks!

The kernel fix (comment #77) only checks for the laptop model name, not anything else. So it will only work for "ASUS UX391UA". If you have a different model of laptop then please open a different bug.

https://mailman.alsa-project.org/pipermail/alsa-devel/2018-December/143282.html

The Q325UAR is quite different from the UX391UA so as @vanvugt points out, a separate bug report should be opened for that and any model other than the UX391UA, which now has this issue fixed.

Thank you @Santiago Londoño your solution worked. Just to add I also had to disable secure boot else it was not booting up.

Thank you @Santiago Londoño. I spend a lot of hours trying to fix this problem on my ux533fd. You saved me)

I have the same problem on Asus Zenbook UX430U. Upgrading to kernel 4.20.16 using ukuu did not fully solve the problem. It worked after the first boot, but no longer works after restarting.

Should I open a separate bug?

Update: the sound problem on UX430U is intermittent. Sometimes it works, sometimes it is gone. I haven't been able to see a clear pattern so far. This is definitely not a hardware problem since everything works rock solid under Windows (I have a dual boot).

You might be experiencing an issue caused by the way Windows handles powering off the sound card. Restarting from Windows yields a non-functioning sound card in Linux. A full shutdown from Windows and subsequent power-on will allow sound to work in Linux.

This bug report is for the UX391UA and has been confirmed as fixed - please open a new report specific to your issue if required.

The kernel fix is not released to updates, we just have it committed to git.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

The bug is back for me with kernel :
Linux version 5.0.0-25-generic (buildd@lgw01-amd64-008) (gcc version 8.3.0 (Ubuntu 8.3.0-6ubuntu1)) #26-Ubuntu SMP Thu Aug 1 12:04:58 UTC 2019

Sounds working for few seconds, and go down, no sound after 5 seconds.
Works again for 5 seconds after some minutes without sounds

This bug was resolved for a while, nothing was done except updating the system, so probably related to kernel update.
Someone else has the same issue with latest update of Ubuntu 19.04 ?

If the problem has definitely returned after being declared fixed then please create a new bug by running:

Hi,

Not sure how to post my specs, but I've been having the same "no audio" issue, which I also believe is related to Windows 10's shutdown behavior. To test this (while no audio was available in Ubuntu 19.04), I started up Windows 10, disabled fast boot in the power settings. Did a full shutdown. Then booted into Ubuntu and audio was once again available.

Not sure if this was dumb luck, or a significant result. I'll be glad to share any more details if it will help solve the problem.

Jonathan,
