Model BOM-WXX9 - help a newbie out

[raizor154]

I don't even know if this is the right place to ask for help, but hours and hours of failed fixes brought me here.

I installed Ubuntu 24.04 on a Huawei Matebook D15, model BOM-WXX9, and of course audio is not working. Where do I start? How do I apply the kernel patch? I'm really sorry if I'm a bother, but I'm relatively new to Linux :(

I've already tried this thesofproject/linux#3249 (comment) but it didn't work.

[andreaconsole]

Here you will find the long story for your system:
#28
The solution is not perfect yet, at least with my kernel version, but totally workable.
I can make my kernel (kindly compiled by codepayne, as I am not able to) available for you (even if downloading a kernel from a stranger is not advisable, I promise I am harmless, at least with coding), and then you can just follow the instructions on that page to make it work.
I am no expert, so I cannot provide more support than this.
I just thank @codepayne from the bottom of my heart every time I turn my laptop on.

[raizor154]

That would actually be a life-saver. I really want to get into Linux but that is certainly pretty hard without audio. Any way I can contact you privately?

[andreaconsole]

This is the link to download it: kernel 6.7.4
it is the 6.7.4. It is not the one I have installed, but a following upgrade that should be easier to use. Check #28 and #30 for more details.

[raizor154]

Which one of these packages should I install?

Also, is there a specific reply I should follow in those issues you linked?

[andreaconsole]

1. Both.
2. Not sure, I already forgot most of it... If you have troubles, look for the answer there.
   Read the comment below first, but I am not sure if any of those instructions are applicable in your case. You do not need to apply the "workaround" (the issue with auto-suspend) because this kernel should already include a dedicated patch.

[raizor154]

I did everything in that comment, rebooted my laptop at the end, but still no audio. This is how my alsamixer looks

[andreaconsole]

I am sorry. I was trying to be helpful but I have very little understanding of this topic. Let's wait for a real expert to step in.
As the last resort, I can offer you the kernel I am currently using: [link removed - use link above] . It is older, but personally tested by me.

Stupid question, did you select the right kernel on boot?

[raizor154]

Stupid question, did you select the right kernel on boot?

I'm almost sure I didn't cuz I'm a noob. How do you do that?

[raizor154]

Oh wow. This actually works. I'm about to cry. Weird popping noises every now and then (not really annoying) but it is what it is. Do I have to manually select the kernel every time?

[andreaconsole]

No, it should remember your last choice. Happy to have been helpful!

[raizor154]

Rebooted my laptop and audio stopped working. Rebooted selecting the right kernel manually again and it works. I just need to figure out how to make it select the right kernel automatically.

[andreaconsole]

weird but ok. google is your friend :)

[raizor154]

Done, now it boots with the patched kernel. I don't know what to say. I spent like the past 48hrs trying to get this fixed. Thank you for your help @andreaconsole and @codepayne! I'll keep you posted if there are any more issues.

[zcroll]

i have the same problem guys on my laptop im using fedora 40 with latest version of kernel any help

[selmanparlak]

This is the link to download it: https://drive.google.com/file/d/1MLIvEGaGxfPwmHyAz39JzVp_Vb9PFBiy/view?usp=sharing it is the 6.7.4. It is not the one I have installed, but a following upgrade that should be easier to use. Check #28 and #30 for more details.

Can I have access for a drive link.
I am newbie too . I didn't understand very well but I want to try it .

[andreaconsole]

Link updated. Good luck!

[selmanparlak]

It worked. the sound comes now but the alsamixer setting resets on every restart. i googled it but i couldn't solve it. it worked on ubuntu but i couldn't do it on linux mint. thank you very much.

[j24u]

Hello @andreaconsole, can I also have access to the link.

[andreaconsole]

You'll find the file here: kernel 6.7.4

[j24u]

Thank you lots @andreaconsole

[Uldarenciy]

You'll find the file here: kernel 6.7.4

Could you please give link on these files after Google Drive, for example? File transfer needs a sub.

[Uldarenciy]

[Uldarenciy]

And also 1 question.
Will ti work on Huawei Matebook d 14 amd ryzen 5500u with Everest sound card, Ubuntu 22.04. There are many negative comments even in Huawei official site about this situation. And in the first references in a browser there is no useful links about fixing dummy output error.

[Uldarenciy]

To find this page you need have enough patience)

[andreaconsole]

@Uldarenciy link updated

[Uldarenciy]

@Uldarenciy link updated

the same
9$
or both you have subscriptions?

[andreaconsole]

It's free. It is on my personal web space. Use the link in my comment

[Uldarenciy]

ok, thank you

[Uldarenciy]

need me make back up before installation?

[Uldarenciy]

@andreaconsole
how to set up them?

[Uldarenciy]

not worked for me, set up kernel, chose it in grub

[Uldarenciy]

Thanks anyway

[LeBlumen]

Did you solve the problem?
If not- have you tried openSuse Tumbleweed or EndeavourOS for example?
Since 6.9.4, audio works perfectly because of the implementation of the patch to the main kernel.

[Uldarenciy]

it did not solve problem.
you think so, then i will try these distros.
You have the same laptop?
@LeBlumen

[Uldarenciy]

here is only 6.8.7

UPD: no sound here

[Uldarenciy]

are there any differences between 6.8.7 and 6.9.4 in terms of sound?

[LeBlumen]

My model is HVY-WXX9
But the problem was that after 6.8.0 update I had sound only for few weeks- few updates later I had no sound again.
When I install Ubuntu, I have no sound too. After I installed and updated EndeavourOS to 6.9.4 kernel, my sound came back. There was a topic on bugzilla related to this bug- there was something wrong with acp-pci.c file

Have you tried the newest kernels on both of these distros?
You can update EndeavourOS to the newest kernel with "sudo pacman -Syu" command.

[Uldarenciy]

tried 6.9.3 (no more available stable versions) on ubuntu, still no sound, no sound card in alsamixer. I don't like EndeavourOS since past meeting it). Thanks anyway for your attention

[LeBlumen]

Well, for now I'd like to see if your problem appears on other distros too (meaning- newer kernels, >6.9.4).
From my experience, I can tell you that I didn't have sound (and still don't have it) on Ubuntu. I don't know why. Even if the kernel is updated, no proper output appears in sound settings.
I'm not sure if there could be any differences between the kernels from different distributions but I tested Arch-based distros and tumbleweed with the newest kernels (starting from 6.9.4 for since then a patch was uploaded to the mainline kernel) and my sound works. Officialy the first patch was added to 6.8.0 and it did work for few weeks but it stopped.
EndeavourOS was just an example of rolling distros with the newest kernel. You can try different ones. Thing is that you should try something starting from 6.9.4.
If it doesn't work, you should wait for codepayne to help.

[Uldarenciy]

@codepayne,
yet released 6.9.9, still the same problem

[Uldarenciy]

Anybody knows, if this problem exists, can i connect my headphones (in settings -> sound nothing changes, still dummy output)?

[zcroll]

@Uldarenciy same problen the only thing you can do is use bluethoth and forget you have speakers hahaha

[Uldarenciy]

bluetooth works bad, usually you need reswitch bluetooth headphones several times

[zcroll]

@Uldarenciy use bluetooth manager and change the profie to

it work fine with noise cancelation and reduction test out

[Skiestrixx]

@LeBlumen How is your audio doing on arch based distros? I tried fedora last summer but the audio doesn't work out of the box.

Edit: any distros you guys can recommend that the audio works out of the box I want to slowly get away from windows. Thanks

[LeBlumen]

@Skiestrixx Currently I have a new PC, so this problem is no longer my concern but the last distro I had was EndeavourOS. Audio used to work out of the box. I think it did also work on openSUSE Tumbleweed.
