Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

I have just done a fresh install on a Huawei Matebook 14 AMD 2020 with the following configuration:

  • Kernel: 5.8.14-arch1-1

  • CPU: AMD Ryzen 7 4800H

  • GPU:Integrated RX Vega 7

The laptop is running fine using Windows including all audio input/outputs. However, when I plug in any headphone into the combo jack under Linux, I hear significant coil whine-like static while the microphone on the headset is not detected at all. I tried various combinations of

options snd_hda_intel model=[MODEL]

including "auto", "headset-mic" and "dell-headset-multi" as well as any options mentioning the ALC256 codec as was suggested by the wiki and here on this forum. However, none of them showed any improvement. I noticed this possible related thread on a Huawei Matebook D 2020, AMD Ryzen 5 3500U which is another CPU generation but the owner did not report any static and the thread got no updates. I tried on linux-mainline-5.9-1 and noticed that the "acp" listings for card 2 are gone, but with the same results regarding static and headphone mic detection.

Re: Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

With which adjustments regarding modules was the above output produced?

Can you post 

amixer -c1

Re: Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

Thank you for the swift reply. The above was with 

options snd-hda-intel model=dell-headset-multi

set in /etc/modprobe.d/alsa.conf as the only adjustment regarding modules. I can post again without the line if that helps. See below for the output of amixer -c1.

Re: Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

Got a brand new Matebook AMD 2020 (the small one, with a AMD Ryzen 5 4600H) which has the same issue.

I've still kept my Windows partition until this issue is fixed or at least has a workaround.

On my Windows partition, I've dug into the registry and found that maybe the pins are wrongly announced by the BIOS.

Based on https://www.reaper-x.com/2012/02/13/how … cks-ports/

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0001\Settings\Drv8981_DevType_0256_SS1e833e33]
"Pin12"=hex:01,00,00,00
"Pin13"=hex:01,00,00,00
"Pin21"=hex:22,00,00,00
"Pin19"=hex:30,00,00,00

With the following meaning for the values:

"00 00 00 00" = Line-in
"01 00 00 00" = Mic-in
"02 00 00 00" = Headphones
“03 00 00 00″ = Front speakers 2nd Output
"04 00 00 00" = Front speakers
"05 00 00 00" = Rear speakers
"06 00 00 00" = Center / sub-woofer
"07 00 00 00" = Side speakers

Whereas on Linux : 

cat /sys/class/sound/hwC1D0/init_pin_configs 
0x12 0x90a60130 => Internal Mic
0x13 0x40000000 => Unused
0x14 0x90170110 => Internal Speaker
0x18 0x411111f0 => Unused
0x19 0x411111f0 => Unused
0x1a 0x411111f0 => Unused
0x1b 0x411111f0 => Unused
0x1d 0x40759a05 => Unused
0x1e 0x411111f0 => Unused
0x21 0x04211020 => Jack Headphone

So I guess pin 13 could be connected to the jack mic.


I'm playing around with several model values for hda-snd-intel module and try tweaking /lib/firmware/hda-jack-retask.fw to patch the pin routing but no success so far.

If someone knows how to drill this down I'd appreciate.

Re: Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

This issue seems to affect all Huawei AMD laptops, this bug report on the Huawei WMI driver is for the Matebook D15 AMD 2020. So far it seems that no one has found a solution. I tried with hda-jack-retask on my Matebook 14 AMD 2020 as well but no luck so far. Regarding the issue reported upstream, I am not sure if the WMI driver is the correct place to report though as it affects ALSA rather than WMI.

Re: Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

That's very sad. I tried to use the internal mic but the sound is unacceptable. It catches too much noise while using the laptop (fan noise, touchpad pressing, keyboard typing). Also the static noise in headphones is too annoying, so I have to take off the headphones whenever I'm not listening to music.

Re: Huawei Matebook 14 AMD 2020 - Static and headset mic not recognized

I agree this looks more alsa-related than huawei-wmi-related.

I've seen some Huawei-specific code in 

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/pci/hda/patch_realtek.c

Nothing worked for now.

For now I cheat by using an external USB to jack adapter (https://aliexpress.com/item/1005001350091638.html).

On Huawei Matebook 13 I have:

"Pin12"=hex:01,00,00,00
"Pin21"=hex:22,00,00,00
"Pin19"=hex:30,00,00,00

and the headset mic is working fine (on Windows 10). So, I guess it might be a wrong pin for mic.
