I have an hp envy laptop. It has 2 very cool buttons that disable the mic and the camera. The one for the camera works, but the one for the mic does not. It worked on Windows.

This is mi inxi:

Is that the (fn+F8) key?

OK, I have an HP Elitebook G1 that has the same mic button, this is how I fixed it. You have to add a custom mapping udev rule.

From Terminal:
sudo nano /etc/udev/hwdb.d/61-hp-mic-mute-hotkey.hwdb

Add the following;
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnHewlett-Packard*:pn*x360*:pvr*
KEYBOARD_KEY_81=f20 #Fn+F8 on x360, map to F20

Save the file by running:
Ctrl + o
Ctrl + x

Then update your hardware with these commands and reboot:
sudo systemd-hwdb update
sudo udevadm trigger

I got this from an Arch wiki when I was setting up my laptop… works for mine. If it doesn’t just remove the file and run update commands to remove.

Unfortunetly it didnt do anything :slightly_frowning_face:
So I should delete that file I created and run:

sudo systemd-hwdb update
sudo udevadm trigger

again and reboot?

Yes remove file and update before moving on.

I found the link, this is where I got my notes: HP EliteBook 840 G1 - ArchWiki

7

Btw thats the output I get for that update (I still haven’t deleted this file).:

sudo systemd-hwdb update                                         ✔ 

[sudo] password for john: 
/etc/udev/hwdb.d/61-hp-mic-mute-hotkey.hwdb:2: Property expected, ignoring record with no properties.

maybe something is wrong here?

Can you post the contents of the file as you have it now?

On my notes on the second line after …81=f20, I have no space between #Fn +F8, but on the wiki it does, maybe that makes a difference, on my laptop it does have the space.

11

Okay I added the space, were gonna see in a second

12

It also did nothing. And I got the same info about it ignoring it bla bla bla. :confused: What now?

13

I had changed the EliteBook name to x360 thinking it was just a label… but maybe try it exactly as it is on the wiki? Can’t hurt.

14

@DeLinuxCo
But now that Im looking at the wiki
Shouldnt there be a space after #?

Yes, my bad, that is what I meant.

16

That also didnt do anything :confused:

17

I just realized that you are running Gnome, are you using Wayland, because that may be why it is not working. My System is Cinnamon Desktop which uses X.

18

I think its turned off

That’s as far as I can go… the issue is surely a key binding and F8 is F20…Web search time.
