Re: No sound (Dummy output) Huawei matebook d15
Okay, we should undo that with this:
I'm afraid at this point I just don't know where the problem lies so can only guess at stupid things that might work, but probably won't.
Stupid guess #1: Try suspending the machine then waking it back up and testing your sound.
Stupid guess #2: See if there's anything audio related in your BIOS. Turn it (if you find something) off for one boot, then turn it back on for the next boot and test your sound.
With both the newer sof driver and the legacy driver your built-in sound options are not being discovered properly. The suggests to me it might be a kernel issue. We may need to wait for Ubuntu to fix their kernels.
EDIT: You should also remove the previous edit we did with this command:
Code: Select all
sudo rm /etc/modprobe.d/probe-fix.conf

and your second guess is not stupid, actually many people reported that this worked for them. look

It works for a very few people, so I never hold out hope that it'll work for the person I'm trying to help.
I'm afraid I'm out of ideas at present. I was off the forum for several months and have lost a bit of my touch on helping with these things. If I think of anything new to try, I'll send you an email letting you know I'm posting something here.

Re: No sound (Dummy output) Huawei matebook d15
Hello, samina, skorzen and markoshaq.
Has anyone of you three tested the Linux Mint live system desktop, before installing Linux Mint on your Huawei Matebook D14/D15?
In case anyone of you three has done so, did the sound work on the Linux Mint live system?
I wonder a bit, because samina's inxi report only holds 2 lines for "Audio": whereas my "Audio" section looks like this:
Yes, I know that Dell is not Huawei. I just wished to give an example on what the "Audio" section looks like on a machine where sound does work.
Best regards,
Karl

Re: No sound (Dummy output) Huawei matebook d15
OK. Another search for "sof-audio-pci":
Came across an Arch Linux hit from 2020, which talked about the need for a software package named sof-firmware.
https://bbs.archlinux.org/viewtopic.php?id=260139
OK. But we are Ubuntu based, not Arch Linux based.
Came across a Ubuntu 21.04 hit, which mentioned firmware-sof-signed.
https://ubuntu.pkgs.org/21.04/ubuntu-mu ... l.deb.html
OK. Ubuntu 21.04 Hirsuite is too new for Mint 20.x.
Nonetheless, something like firmware-sof-signed seems to exist. - Maybe it is really needed.
Out of curiosity I checked on my older Mint 19.3 system (base: Ubuntu 18.04): Not available from the Ubuntu repos on Ubuntu 18.04.
But maybe for Ubuntu 20.04, which would then help on LM 20.x as well?
This page might suggest that firmware-sof is only available for Ubuntu 21.04 and 21.10 at this point in time: https://pkgs.org/download/firmware-sof-signed
So for the moment the best which I can come up with is this Askubuntu article:
https://askubuntu.com/questions/1243369 ... -audio-pci
where the Grub commandline gets changed to read:
It is possible to test whether this has got the desired effect at boot time by
+ entering the Grub menu
+ pressing E for edit the pre-select boot menu item
+ adding tos the vmlinuz line:
+ pressing <F10> to continue booting with the additional parameter
Sound may or may not work, because it is only an attempted workaround for the problem that the needed firmware-sof-pci module is not present in linux-firmware, yet, on Ubuntu 20.04.
How to set this parameter permanently can be found in the linked Askubuntu article.

Re: No sound (Dummy output) Huawei matebook d15
Guys, I sent the computer to the Maintenance center of Huawei.
they were able to fix it through the Hardware, it didn't take more than 2 minutes.
I didn't understand what exactly they did. It wasn't hardware damage at all based on what I was able to know. they did not tell me what they did, but what I think they did is that they reset the CMOS or the motherboard somehow, or maybe they unplugged the sound card and re-plugged it again.
now the sound and all the functionalities are working.
If you have a Huawei matebook d15, just send it to the maintenance center, and they should fix your laptop for free.
thanks for your help I appreciate it

Re: No sound (Dummy output) Huawei matebook d15
Is there really no way knowing just what they did? I'm struggling to make audio work on a similar device (Huawei Matebook D15 2021 with Intel i7 Tiger Lake). It's just driving me mad.

And is this with linux running or did they reinstall Windows? Or was this not even a software fix? (x_x)
I've been trying to find a solution for weeks now and this is not something that I expected.

Re: No sound (Dummy output) Huawei matebook d15
No, they didn't even know the hard-disk encryption password,
I did not give them the password to unlock the laptop.
I was just stupid because I did not ask the guys who fixed it.
they made something with the hardware, I'm sure.
But I don't think they changed any part, I believe they unplugged something while fixing a power button issue (another problem happened because my laptop fell to the ground, then the device power button stopped working, maybe something in the cables inside moved or unplugged by the shock).
Maybe they unplugged and plugged again in the battery/sound card / reset the CMOS (a button on the motherboard [I couldn't locate where's that button on my laptop ] ) then it magically worked.
My suggestion is to throw your laptop on the ground as I did, and take it to Huawei technical center to fix it, sometimes crazy stuff like that just works.
Ah, forgot to mention, that a short time after the sound was fixed on my laptop, my SSD got damaged for no reason. I was having my laptop shut down once every while without any reason. and after some days of having this problem, the SSD was dead and I lost all of my data, and I bought a new SSD slot. just something to mention, perhaps there's something related to SSD damage?

Re: No sound (Dummy output) Huawei matebook d15
This could be a hardware configuration issue as the sof-project github repo issue mentions(not detecting some pins automatically) and resetting the hardware could have fixed it.
https://github.com/thesofproject/linux/issues/3248
No thanks, I will wait until someone comes up with a less-drastic solution than throwing it on the ground (moreover I reside in a small town from India and couldn't find any Huawei service center nearby).

Re: No sound (Dummy output) Huawei matebook d15
i received my Matebook D15 AMD today. no sound for me either. updating the kernel did not resolve the issue, but this time "Dummy Output" appeared.
seems like this issue has been ongoing since 2021. can we expect the problem to resolve sometime in the future?
