Firmware Huawei Mate 20 Pro

[Juanjo Pollreisz]

Justbought an HUAWEI MateBook D 14 and installed Archlinux with KDE Plasma. Everything is going as great as I think of archlinux and I only have sound and webcam to go to finish the setup. Then I stuck on the sound part.

Before doing anything related to sound there was no sound coming out of the speakers from any application (which can be expected). When I checked sudo dmesg grep audio I found some error messages about somthing missing around 'sof' (sorry that I am not giving out the exact dmesgs here as doing so will require me to uninstall sof-firmware), so I headed towards sudo pacman -S sof-firmware and reboot. amixer continued to complain

I put this information into Google and finally bumped into this Ubuntu guy. I actually did not quite understand this operation. After encountering several mentions of this thread from different places I decided to give it try. I changed

I barely can continue addressing the problem on myself from this point. Something strange I noticed during searching was that others' laptops usually have at least two cards (a CARD 0 and a CARD 1) when aplay -l and something like 'stereo' when aplay -L, but I only got bunch of 'HDMI's and nothing of 'stereo'. Could this be hinting the cause of the underlying problem? Lots of thanks to any help provided!

Not sure why you installed the sof-firmware, the snd_hda_intel kernel module should work fine. You seem to be going round in circles trying to use alsa, may be consider installing pulseaudio and pavucontrol.

P.S.1. During these times I have bought an external USB soundcard and this one works out of the box. Happily playing games. And if I get too happy I will dive in sound systems again and give up again

P.S.2. My roommate happen to have just made a Windows-to-go USB stick. By booting into Windows the speakers of my laptop work fine (I feel like receiving sounds from the heaven when they are working). This indicates that my sound system do not have hardware faults.

The Western Digital SN730 NVMe SSD comes pre-configured with a logical sector size of 512 bytes and a physical sector size of 4096 bytes. Switching the logical sector size to the native 4096 byte size might improve performance as indicated by the vendor. This will erase all data on the device! To format the SSD with a different sector size, run

Previous devices got their BIOS updates published on the Huawei homepage which could be manually installed[1]. However, currently no updates are available for download even though this device receive the update to BIOS version 1.06 after launch.

The Huawei WMI driver v3.3 to expose battery protection thresholds was merged into kernel 5.5[2]. There is an issue[3] where the hardware reports incorrect values for the charge thresholds, preventing battery protection from working. The maintainer of the driver has stated this should be fixed in userspace[4].

This will enable battery protection (in this case, the device will stop charging at 70%). In order for matebook-appletAUR to run without superuser rights, add yourself to the huawei-wmi user group since the thresholds are still read-only to non-root.

Alternatively, huawei-wmiAUR will set the group write privileges. This will also take care of the thresholds resetting randomly upon reboot by automatically reinstating the battery charge-thresholds. For more information, see this guide.

Speakers and internal microphone work out of the box although the internal microphone picks up a significant amount of noise. To correctly detect a headset with microphone, use the alc255-acer,dell-headset-multi for the value of model=, as explained in Advanced Linux Sound Architecture#Correctly detect microphone plugged in a 4-pin 3.5mm (TRRS) jack.

The Goodix fingerprint reader is currently unsupported officially. There is a fork however, which aims to provide support for the device (along with other similar goodix ones). The driver is currently in testing but there is an aur package for it libfprint-goodixtls-gitAUR which works with fprintd
