I installed Ubuntu 18.04 on my new HP elitebook 850 G6 after erasing windows. I could not get audio input part working though.. Fn F8 key is orange all the time and this is how settings looks like.


I installed pavucontrol, but that didn't change anything. What I have noticed is that I cannot check "set as fallback" permanently.


Also tried editing /etc/modprobe.d/alsa-base.conf by adding

options snd-hda-intel model=auto

Sound control still does not recognize any microphone

  • Maybe check my answer on this post askubuntu.com/questions/508221/…. Some controls only show up in pavucontrol when you already started a program which needs mic input.

    @senseiwu - yes that what I did as well - which led me into another sad Ubuntu ditch - the sound and mic quality of HFP (hands free protocol?, as opposed to A2DP) is dismal, thats why I use arch on my other laptop - the internal mic works, see bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1838151 for more context

    IIRC the Fn Key switch is independent from the OS - have you tried booting in the BIOS and pressing the Fn+Key switch ? Its also worth checking out all the BIOS options, since HPs Elitebooks series is for enterprise use, there are a ton of options you would not normally see in a BIOS. I just checked the BIOS manual for HP and there seems to be an option to enable/disable it there (page 40) Apr 1, 2020 at 6:10

I have installed dconf-editor and dconf after start of the gui the search-function is active and you could use the keyboard. The keyword "volume" drives to a button named "use-mediakeys" on or off?
