Microphone not working on Omen 16

Hi
I've spent more than 24 hours trying to get my internal microphone to work but without success. Sound works just fine, same with bluetooth mic.

Tried a bunch of things like https://wiki.archlinux.org/title/PulseA … Microphone

also playing with a combination of different module params for snd_hda_intel :

options  snd_intel_dspcfg dsp_driver=1
options snd-hda-intel power_save=1
options snd_hda_intel  index=2  dmic_detect=1 enable=1
options snd_hda_intel index=2,1,0 id=NVidia,Generic,Main  power_save=0 model=generic

As a last resort I tried installing ubuntu on a different partition to showcase microphone functionality but had the same results... My fear is that my sound card is not yet properly supported (got sof-firmware, alsa-firmware, alsa-ucm-conf )

my full alsa-info
http://alsa-project.org/db/?f=1d9190acd … b49c5e3aeb

Any help is welcome !

Re: Microphone not working on Omen 16

If this actually needs a dmic then you will disable it with that kind of configuration. Remove that entire file(s) and repost the output of of alsa-info.sh when you are on a sof-firmware based setup.

Generally HP laptops are notorious for a broken verb table, hope for a BIOS/UEFI update or you might be SoL

Re: Microphone not working on Omen 16

Removed all the files as indicated and tried to get sof loaded as it wasn't before but that doesn't work (doesn't appear in dmesg at least):
first got the latest version of sof and installed as per https://github.com/thesofproject/sof-bin
then

blacklist snd_hda_intel
blacklist snd_soc_skl 

got the corresponding output
http://alsa-project.org/db/?f=d40426800 … 71e02a78d7

I had no soundcard detected at that point si I removed the blacklist
http://alsa-project.org/db/?f=74a55a60d … 8fad7763b0

What am I missing/doing wrong ?

Re: Microphone not working on Omen 16

You could've just installed the sof-firmware package. But having that and needing sof-firmware and setting up options  snd_intel_dspcfg dsp_driver=1 will logically conflict and bypass sof. And in the "corresponding" output you still had

snd-hda-intel dmic_detect=0,snd_intel_dspcfg.dsp_driver=1

on the kernel parameters. Make sure those aren't set.

If that is still the output (even after making sure there's no trace of dmic_detect=0 nor snd_intel_dpscfg anywhere - they will expectedly disable mic support if you have HW that actually needs them to be set) then it doesn't need sof, but still just marking it as generic reads weird. FWIW you do have a mic but

arecord -Dhw:2,0 test.wav

doesn't work I assume?

Re: Microphone not working on Omen 16

The output is still the same..
http://alsa-project.org/db/?f=0ab4f6d1c … 2b32484175

arecord -Dhw:2,0 test.wav

does indeed not work ( aplay does not read any sound)

Re: Microphone not working on Omen 16

You should see a sof card... You are likely still exporting those values somewhere.  What do you get from

cat /proc/cmdline
pacman -Qkk sof-firmware
grep -ER 'snd|sof' /{etc,usr/lib}/modprobe.d
sudo dmesg

You should see something like (from a random google result) http://alsa-project.org/db/?f=23ceaa41c … b4266eca0f note that it doesn't use snd_hda_intel anymore for the internal card but a sof variant.

Re: Microphone not working on Omen 16

Decided to not give up and tried to test if microphone works on other distributions; first tried manjaro and... the mic works !!!!

Manjaro alsa-infos:
http://alsa-project.org/db/?f=7566370c7 … f475e5d5f5
Arch alsa-info:
http://alsa-project.org/db/?f=2dc3934d7 … 1e5a46ba2f

Gonna check where the differences lies and retry on Arch.

Re: Microphone not working on Omen 16

One obvious difference that the Manjaro kernel is on LTS and the Arch kernel on stable, try linux-lts

Another thing but then arecord should have worked at least is pipewire-{pulse} instead of pulseaudio.

Re: Microphone not working on Omen 16

Switching overt to linux-lts and using pipewire didn't work either but I noticed something suspicious from diff checking :

Dunno if that means anything ?

Re: Microphone not working on Omen 16

It doesn't, you are only looking at the playback not the recording devices and subdevice 0/1 simply means that the device associated with that subdevice is currently actively in use i.e. you are currently playing back/listening to something. And the irq's are likely to change from boot to boot.

You are likely mssing something more obvious, can you compare alsamixer mixer states between the two? Can you post

amixer -c2
sudo fuser -v /dev/snd/*
pactl list cards
pactl list sources
pactl list source-outputs

during a recording attempt, possibly from both?

Re: Microphone not working on Omen 16

Just a side note: The dmic of my laptop with ryzen 5600U is detected if

snd_rn_pci_acp3x.dmic_acpi_check=1

is added to the kernel command line.

Re: Microphone not working on Omen 16

I also have an Omen 16 (with a Ryzen 7 6800H as the CPU), and the built in microphone isn't working on it either. I don't see sof being used anywhere despite having sof-firmware installed and not having messed with audio specific configuration files at all (I never needed audio input until now, audio output to my earphones works fine out of the box and the microphone included with my earphones also show up).

"arecord -Dhw:2,0 test.wav" fails with "Sample format non available", adding one of the formats it says are available (S16_LE and S32_LE) then fails with "Channels count non available".

Blacklisting snd_hda_intel causes the speakers to disappear too, and adding "snd_rn_pci_acp3x.dmic_acpi_check=1" to the kernel command line doesn't fix the problem.

Re: Microphone not working on Omen 16

It turns out that to get the microphone to work I had to add a quirk entry to the acp6x kernel driver by applying a patch like this one: https://lore.kernel.org/all/20230227234 … gmail.com/ with the board name adjusted with what I got from alsa-info ("8A42" instead of "8A43" in my case).
