Mic not working

Hi everybody, I hope someone can help me.
I have installed Manjaro Gnome for the first time on a new laptop: a ThinkPad x1 Carbon gen 8.
Everything worked fine apart from the microphone.
I tried to look around for some hint but nothing I tried worked.
Here is the output of a couple of commands that in general al useful for understanding the problem, I hope this can help you in helping me! :wink:
Thank you very much in advance!!

This laptop has a digital microphone array

ThinkPad X1 Carbon Gen 8 | Our Best Business Laptop | Lenovo US
4 x 360-degree far-field microphones

but PulseAudio data is showing legacy driver snd_hda_intel in use that does not support digital array microphones

You may need to install package sof-firmware to get the Sound Open Firmware driver to support the microphone array

pamac install sof-firmware

Hi!
Thank you for the explanation!
I tried to execute your command but it says the new software is already installed:

[user ~]$ pamac install sof-firmware
Preparing...
Warning: sof-firmware-1.8-1 is up to date -- skipping
Nothing to do.
Transaction successfully finished.
[user ~]$

So what should I do now?

System is using driver snd_hda_intel for onboard audio that does not support internal digital array microphone
The digital microphone requires driver sof-audio-pci provided by package sof-firmware

Linux hardware scans often do not show much information about audio devices
but most other users with X1 Carbon 8th gen laptops appear to have the correct driver
https://linux-hardware.org/?id=pci:8086-02c8-17aa-22be

I suggest you run a full ALSA diagnostic to see if there are any error messages for hardware or drivers

sudo alsa-info.sh --upload

Thanks for the reply!
The output of the full ALSA diagnostic is at the following link:
http://alsa-project.org/db/?f=7a70dd50bffa0563fe9d6ea3f74527e71d6d2cbd

Do you see anything strange/problematic?

ALSA data is showing a modprobe option to force use of the snd_hda_intel driver

!!Modprobe options (Sound related)

snd_intel_dspcfg: dsp_driver=1

so ALSA only detects the headset microphone jack

If the system was using the sof-firmware driver the digital capture devices should be detected like this
