Microphone not working on HP EliteBook

[Lurre]

Hi!

Microphone not working on my laptop (HP Elitebook 840) and running according to specs:

Bang & Olufsen, dual stereo speakers, 3 multi array microphone

any idea?

running:

OS name: Clear Linux OS; Build ID: 33330

lspci | grep Audio

results in:

Multimedia audio controller: Intel Corporation Cannon Point-LP High Definition Audio Controller (rev 11)

UPDATE: Output analog sound doesnt work either I just realized. I suppose it could relate to this other question.

In other distros you would add this to /etc/default/grub

snd_intel_dspcfg: dsp_driver=1

Clear Linux doesn’t use GRUB.
Is this a kernel option?

[NathanW]

Yes, it’s a kernel option.

[Lurre]

That path doesn’t exist as per doct0rHu reason I assume.

[doct0rHu]

Set snd-intel-dspcfg.dsp_driver=1

How do you pass a boot parameter to the kernel on boot?

man clr-boot-manager covers the configuration options towards the bottom. Essentially create a file in path /etc/kernel/cmdline.d/*.conf and the contents of that file will be added to the kernel cmdline after each kernel update. To update the kernel parameters for next boot you’ll need to run this for it to take effect. clr-boot-manager update Via cat /proc/cmdline you can verify whether the new kernel parameter has been applied after boot.

This worked to get the sound going, however this didn’t make the input audio to work so partially solution this

[doct0rHu]

Can you see the correct input device in sound settings?

[Lurre]

No, no option showing at all

[doct0rHu]

What do you mean? You cannot see anything in gnome control center?

[Lurre]

In settings-> sound showing no options in the input-device field. I even rebooted and nothing

[doct0rHu]

I don’t know. How will you solve this on other distro?
