Microphone no more detected by KDE

This week microphone just stopped been detected by Manjaro.
I tried both linux54 and linux-latest (linux58 as of writing).

Here some debug info:
$ sudo dmesg | grep snd | xclip -selection clipboard

Just to have an idea, here Audio Volume Settings screenshot:

Thanks in advance for hints or solutions! :wink:

ALSA data for kernel v5.4 is showing not showing details for audio device correctly

00:1f.3 Audio device [0403]: Intel Corporation Cannon Point-LP High Definition Audio Controller [8086:9dc8] (rev 30) (prog-if 80)
	DeviceName: Onboard - Sound

this system has an 8th generation Intel CPU and probably has an internal digital microphone array (DMIC) that is not supported by kernel v5.4

you need to use kernel v5.8 and install package sof-firmware to get the new driver for the internal DMIC

System also requires a later version of Pulseaudio (v13.99) that includes patches to support the new firmware
the simplest way to get that at the moment is to change to Manjaro testing branch

Problems with audio on laptop

sudo pacman-mirrors --api --set-branch

and then refresh-mirrors and get updates

sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu

With kernel 5.4 mic worked great until a week ago, however!
What is changed?
I’m not sure I want to ride the crest of the testing wave! :wink:

edit: I’m running:
sudo pacman-mirrors --api --set-branch testing

I updated as stated above, but I can’t get rid of problems:

Any other idea? Thanks in advance!!!

inputs and outputs appear to be detected ok in dmesg

suggest you check alsa-info.sh again to see if device is recognised
and if one of the snd_sof drivers is loaded as well as snd_hda_Intel driver

but it may be a problem in PulseAudio, so check if audio device is detected there with:

pacmd list-cards

New sudo alsa-info.sh output is HERE
It says:


!!Loaded ALSA modules
!!-------------------

snd_hda_intel

but no snd_sof ALSA module…

pacmd list-cards seems to detect it:

Still, thank you for you support!

I started Manjaro from USB and mic works well, damn!

I runned sudo alsa-info.sh there: output HERE

I runned even:

[manjaro@manjaro ~]$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3254 Analog [ALC3254 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The Profile for the card is set for output only

active profile: <output:analog-stereo>

use this command to change the Profile to ‘Analog Stereo Duplex’ (output + input)

pacmd set-card-profile alsa_card.pci-0000_00_1f.3 output:analog-stereo+input:analog-stereo

But I do not expect that to get everything working again. An external microphone might work but the internal microphone is not likely to work with only the snd_hda_intel driver

The pci device detected name still looks wrong

00:1f.3 Audio device [0403]: Intel Corporation Cannon Point-LP High Definition Audio Controller [8086:9dc8] (rev 30) (prog-if 80)
	DeviceName: Onboard - Sound

I would expect the 2nd line to show the Dell device ID number

    Subsystem: [1028:08a6]

but the ID code is detected in the !!HDA-Intel Codec information section :confused:

Subsystem Id: 0x102808a6

I find a solution from this thread, which reference to The Arch Wiki:

  1. I determined the card and device number of my mic with arecord -l
  2. I edited /etc/pulse/default.pa and insert a load-module line: load-module module-alsa-source device=hw:0,0
  3. Restarted

And now it works correctly.
I don’t think this is a problem solution but a workaround… But it works for now!

Thanks @nikgnomic … The mistery remains unsolved, for now, but I have a solution!

That is a good and simple solution

The only thing that might be a problem in future is if the snd_hda_intel driver is replaced by the new firmware driver, but I would not expect it to stop audio working
