Internal microphone does not work

English Hardware
1

Greetings to Forum users
This is my first message in the Forum because I have a problem with the internal microphone that does not work.
I have an ACER Swift3 and in the past the microphone worked; at that time with the command Inxi -Aa I got:

After several updates when recording a message the microphone does not work; even with the command “arecord -vvv -f dat /dev/null” I get

Also to check with “Inxi -Aa” now I have:

gianmario@swift3:~> inxi -Aa

    driver: snd_soc_avs v: kernel alternate: snd_hda_intel,snd_sof_pci_intel_skl

    status: active 2: wireplumber status: active 3: pipewire-alsa type: plugin
    4: pw-jack type: plugin tools: pactl,pw-cat,pw-cli,wpctl

I noticed a different driver, in the past it was “snd_soc_skl” while now it is
“snd_soc_avs” and I think this does not make the internal microphone work.
I also tried to insert “snd_soc_avs” in “blacklist” in the “/etc/modeprobe.d” folder but at the reboot no sound card worked. :cry:
Thanks to anyone who can help me

Are you really on Tumbleweed (with the -longterm kernel?) or on Slowroll?

And, BTW, welcome to the openSUSE Forums!

Hallo OrsoBruno,
many thanks for the welcome: I didn’t see the PRESENTATION section on the forum and I went straight to composing the first help message.
I confirm that I’m using Tumbleweed with Kernel LONGTERM

If it helps, I got some earphones with microphone and connected them to the PC jack and the earphones microphone works!

A quick search for your HW (8086:9d71) returns several results, many dating back a few years, so that is definitely problematic HW.
Just as a quick check, can you boot adding snd-intel-dspcfg.dsp_driver=1 to the kernel command line to see if the “legacy driver” works?

6

I also thought of something like this, but how to do it? I think with YAST, can you tell me?

YAST → System → Bootloader → Kernel Parameter ?

At now I have

splash=silent resume=/dev/disk/by-uuid/2afbd344-9c18-49a6-8f44-3188f2b4cb76 quiet security=apparmor rd.driver.blacklist=nouveau
7

The YaST way is useful to make it permanent, if it works. For a simple test, at the GRUB menu hit “E” for “Edit”, scroll down to the line beginning with “linux” and add snd-intel-dspcfg.dsp_driver=1 then hit F10 to boot.

8

I followed your instructions and now the driver in use is SND_HDA_INTEL

gianmario@swift3:~> inxi -Aa

In the KDE Audio settings there is now “Analog Stereo Duplex” which was not there before.
However the internal microphone still does not work :cry:

The strange thing is that last year when I first installed Tumbleweed the internal microphone worked immediately right away and the driver in use was “SND_SOC_SKL” :thinking: :thinking:

The skylake sound drivers are still work in progress apparently…
Is the sof-firmware package installed?

zypper se -i sof-firmware

If not so, try to install it and reboot (without the snd-intel-dspcfg.dsp_driver=1 option):

zypper in sof-firmware
10

Sof-firmware is installed:

gianmario@swift3:~> zypper se -i sof-firmware

gianmario@swift3:~>

In the past with Manjaro I had the same problem and bypassed using headphones.

After the first installation of Tumbleweed and with the driver for Skylake or better Kabylake for my PC the internal microphone worked; I don’t know if the driver is present in Kernel 6

11

No, apparently:

LT-B:~ # modinfo snd_soc_skl
modinfo: ERROR: Module snd_soc_skl not found.
LT-B:~ #

You may try snd-intel-dspcfg.dsp_driver=2 or snd-intel-dspcfg.dsp_driver=3 and see what it gives.
There is also an option snd-intel-dspcfg.dsp_driver=4 but since the avs driver doesn’t work I don’t think it will work either.
If nothing of the above works, wait for somebody with Skylake HW to chime in and possibly offer less obvious solutions.

For details see the last line of modinfo snd_intel_dspcfg

OK OrsoBruno,
many thank for your effort, I will try your advice during the next week end and I will inform the Forum :wink:

This afternoon I ran some tests following OrsoBruno’s advice and here are the results:

I also tried option 3 but the result was terrible: no working audio

Hallo,
just to inform you of the situation after reading this as reported by Takashi:

I ran some tests and found that my DMIC works with these two particular commands.

arecord -Dhw:avsdmic,2 -r 48000 -c2 -f S32_LE -vvv > output_S32.wav

and also

arecord -Dhw:avsdmic,2 -r 48000 -c2 -f S16_LE -vvv > output_S16.wav

So as advised here from Takashi I will open a bug into there

From what I understand it seems that the problem of the DMIC is not Hardware because with the right commands the microphone works and records, but there is a “something” missing to be able to activate it from the graphical interface.

I do not know and do not understand what “UCM Profile” is, I hope someone can give me some information to solve the malfunction.

Here a printscreen from my KDE audio setting
