Describe the bug LED on the F7(fn+mic) key does not light up when microphone is turned off

Expected behavior When the microphone is turned off, the LED on the F7(fn+mic) key should light up

Now I tried to install version 3.4 using dkms autoinstall, but it didn't change anything

Sep 29 '21 16:09 m1khal3v

Also I updated the BIOS to the latest version and it didn't help. I attach dumps after manipulations acpidump.txt | dmidecode.txt | dmesg.txt

I have the same problem on the same device. Also the charge limit doesn't work either.

@EnginAcikgoz hello, look battery issue here https://github.com/aymanbagabas/Huawei-WMI/issues/52

Does the led light up when you do

echo 1 | sudo tee /sys/devices/platform/huawei-wmi/leds/platform::micmute/brightness

Sep 30 '21 16:09 aymanbagabas

Does the led light up when you do

echo 1 | sudo tee /sys/devices/platform/huawei-wmi/leds/platform::micmute/brightness

yes, the code is working and led light up.

@EnginAcikgoz this means there is nothing wrong with huawei-wmi. What desktop environment are you using? When I use GNOME or KDE, this simply works fine because these DEs know how to talk to the micmute led interface. If you're not using a DE that recognizes XF86 keys, then you won't get the led to work when you press the key.

The way this works is, when you press the key, the driver fires an event with the code 0x287 which then gets translated to F20 in SystemD. This is because XF86AudioMicMute keycode is beyond what X.Org supports (or something between these lines). The DE keyboard event handler detects the event and mutes the microphone which then triggers the realtek sound hda to set the led using the huawei-wmi micmute led function based on Huawei's sound PCI vendor id 0x19e5 which you can verify when you run alsa-info.sh

@aymanbagabas Thanks for answer

echo 1 | sudo tee /sys/devices/platform/huawei-wmi/leds/platform::micmute/brightness

I use Gnome 3.36.9 and xorg-server 2:1.20.11-1ubuntu1~20.04.2. Could you tell us how to find clues why this does not work on our hardware?

Sep 30 '21 18:09 m1khal3v

@m1khal3v could you upload the output of alsa-info.sh? Also what happens if you mute the mic from GNOME sound settings?

Sep 30 '21 18:09 aymanbagabas

@aymanbagabas http://alsa-project.org/db/?f=bdffc32fb0826fbe78792752b0fade8b4c4a43f7 when I turn off the microphone from the gnome settings nothing happens

k now I see the problem.

It seems like new Huawei devices have a different subsystem id compared to the old ones. Linux-Hardware.org shows devices with this subsystem vendor id HVY-WXX9, KLVC-WXX9, KLVL-WXX9, WRTB-WXX9, MACHC-WAX9, and WRTB-WXX9.

I tried it in manjaro KDE environment and it didn't work.

5.13.19-2-MANJARO

Oct 11 '21 21:10 canack

@enginacikgoz did the module load lsmod | grep realtek? did it load the right module, locally compiled on my machine running Fedora 5.14 kernel, modinfo snd-hda-codec-realtek? are any of SELinux or AppArmor enabled and preventing the module to load, do you get any errors in dmesg? does the sound work in your system? what happens when you mute the mic from the sound settings?

Oct 11 '21 21:10 aymanbagabas

lsmod | grep realtek returns none. i tried sudo insmod snd-hda-codec-realtek.ko and i got this insmod: ERROR: could not insert module snd-hda-codec-realtek.ko: Invalid module format

"dmesg | grep realtek" output:

I can turn the microphone off and on without any problems via ctrl + f7 or the system settings, but in both cases the microphone light does not turn on.

modinfo.txt

Oct 11 '21 22:10 canack

seems like because of the kernel version differences it is not letting you load the module. could you try insmod -f snd-hda-codec-realtek.ko and/or modprobe -f and observe dmesg? if this doesn't work you might need to compile the module yourself

Oct 11 '21 22:10 aymanbagabas

also try after copying the new module to /lib/modules/`uname -r`/updates

sudo depmod -a
sudo modprobe -f snd-hda-codec-realtek

Oct 11 '21 22:10 aymanbagabas

does modinfo snd-hda-codec-realtek returns kernel 5.14?

Oct 11 '21 22:10 aymanbagabas

does modinfo snd-hda-codec-realtek returns kernel 5.14?

No, returns 5.13 modinfo.txt

Oct 11 '21 22:10 canack

k, this is how you'd build the module yourself

clone the linux kernel from https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git, checkout v5.13
apply this patch using git am < [PATCH] 0001-ALSA-hda-realtek-New-Huawei-vendor-ID.patch.txt
follow this guide to build snd-hda-codec-realtek (you don't really want to build the whole kernel belive me) https://yoursunny.com/t/2018/one-kernel-module/. make sure you have your headers then you'd do make -C . M=sound/pci/hda, then copy sound/pci/hda/snd-hda-codec-realtek.ko to /lib/modules/`uname -r`/updates, depmod -a, reboot, and modprobe -f snd-hda-codec-realtek

if everything goes well, modinfo snd-hda-codec-realtek should give you an unsigned module and micmute hopefully works

Oct 12 '21 00:10 aymanbagabas

These are a bit complicated for me. I will try it as soon as possible though. Thank you. =)

Oct 12 '21 01:10 canack

it really isn't tbh, i just need to verify it works before I can submit the patch to the mailing list. here, try this

git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git checkout v5.13 # or whatever matches your kernel
wget https://github.com/aymanbagabas/Huawei-WMI/files/7326045/0001-ALSA-hda-realtek-New-Huawei-vendor-ID.patch.txt
git am < 0001-ALSA-hda-realtek-New-Huawei-vendor-ID.patch.txt
cp /boot/config-`uname -r` .config
cp /usr/src/linux-headers-`uname -r`/Module.symvers .
make oldconfig # accept all default values if any (press enter)
make scripts prepare modules_prepare
make -C . M=sound/pci/hda

if everything goes well, you should get a patched sound/pci/hda/snd-hda-codec-realtek.ko file that you can modprobe -f to test. dmesg -w is also handy to watch for logs and errors.

you could also copy the patched module to /lib/modules/`uname -r`/updates then do sudo depmod -a, so you can use sudo modprobe -f snd-hda-codec-realtek which should use the updated one from the updates directory. verify that with modinfo snd-hda-codec-realtek

Now i have an error on step make scripts prepare modules_prepare:

You probably need to install openssl dev package. In Ubuntu/Debian, the package would be libssl-dev.

@aymanbagabas Today I noticed that the sound in the right earpiece has disappeared, how can I roll back the changes?

UPD: I remove the modified driver and ran sudo depmod -a but it didn't help. After that I tried other headphones and noticed that the balance slider moved all the way to the left. I returned to the center and everything worked as before. Not sure if it has something to do with the driver but suddenly

@m1khal3v @enginacikgoz I've changed the name of the entry in the patch, perhaps this makes a difference? Could you try this instead? Just make sure you undo the previous one in the linux tree git reset HEAD^ && git checkout sound

Still not working. But i got extra information.

just to be sure i did the steps here from scratch and just changed the patch file

git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git checkout v5.15 # or whatever matches your kernel
wget https://github.com/aymanbagabas/Huawei-WMI/files/7507422/0001-ALSA-hda-realtek-New-Huawei-vendor-ID.patch.txt 
git am < 0001-ALSA-hda-realtek-New-Huawei-vendor-ID.patch.txt
zcat /proc/config.gz > .config
cp /usr/lib/modules/5.15.0-1-MANJARO/build/Module.symvers .
make oldconfig # accept all default values if any (press enter)

make -C . M=sound/pci/hda
cp sound/pci/hda/snd-hda-codec-realtek.ko /lib/modules/5.15.0-1-MANJARO/updates/
sudo depmod -a

Still not working but make -C . M=sound/pci/hda gives me this output

Okay, I take that back, 10EC0256 is a realtek driver so snd_hda_codec_realtek should be loaded when you boot the system. /sys/bus/hdaudio/devices/hdaudioC1D0 shows that the loaded driver is in fact snd_hda_codec_generic which is realy confusing.

@aymanbagabas how i can fix audio-micmute trigger?

Nov 29 '21 07:11 sermart1234

@aymanbagabas how i can fix audio-micmute trigger?

when you press the micmute key, do you get Unknown key pressed, code: 0x... in dmesg?

the wmi interface fires a key event when you press a function key. then this gets processed using huawei_wmi_process_key which maps keycodes to linux sparse keymap defined in https://github.com/aymanbagabas/Huawei-WMI/blob/master/huawei-wmi.c#L75

the micmute key works by mapping 0x287 which is usually what you get from the interface, not 198, to KEY_MICMUTE which then Systemd 60-keyboard.hwdb keyboard mapping maps to F20 because of some issue with the micmute keycode being not compatible with window systems. then the desktop environment should handle this key event to mute the mic which then triggers the led trigger audio-micmute and turn the led on.

//{ KE_KEY,    0x287,          { KEY_MICMUTE } },

Dec 05 '21 10:12 sermart1234

@sermart1234 good observation. Huawei-WMI driver creates a new keyboard for the hotkeys which are defined in that table, 0x287 is the micmute keycode extracted from the WMI method. atkbd is the original driver for the keyboard which doesn't handle Huawei hotkeys and instead emit 0xf8 for almost all hotkeys.

Dec 06 '21 15:12 aymanbagabas

@aymanbagabas how do triggers for LEDs work? how can emulate a trigger? Does it depend on the audio driver? should I configure systemd, udev? Or will you just have to write a script for processing the micmute button?

Dec 06 '21 19:12 sermart1234

@sermart1234 AFAICT each trigger is implemented differently in the LED subsystem. if echo 1 > brightness works, then the triggers should work too unless something wrong with the trigger. as you can see in the source code here, we only set the default trigger which can be changed from the LED sysfs interface

Dec 06 '21 20:12 aymanbagabas

@aymanbagabas Should the Realtek driver send events to turn off the LED? or DE?
