I bought a used laptop Asus c436 (i5, Comet lake) and have maneged to install Manjaro 36.
So far its working like charm! Only two issues are touchscreen and sound. I had read the posts in the forum, but couldnt get the sound working. I did install sof-firmware (I think so).
I have ALSA Information Script, but somehow cant post it ;(
Any help will be apropriate.
A link to the ALSA information can be posted using preformatted text button</>

Thanx nikgnomic! Let me try to post it:
So, no one have any suggestions?

Done. Thanx brahma, so looks less paintfull for the eyes
try switching to pipewire:
pamac install manjaro-pipewire wireplumber sof-firmware
it will give you pulse dependency issues, so remove them first, then run the command again;
then install another kernel: go to system settings/kernel and install the 5.19 kernel (dont install the ‘rt’ one);
reboot and check audio
Excuses for the late answer, but after following your advice the system whent to upgrade about 1.3GB, so it took some time. I think the dependencies were removed automaticly. I did install the new kernel 5.19.1 (not the rt one), rebooted, and after running again
pamac install manjaro-pipewire wireplumber sof-firmware it gave me this:
~ pamac install manjaro-pipewire wireplumber sof-firmware ✔ Preparing... Warning: sof-firmware-2.2.1-1 is up to date -- skipping Warning: wireplumber-0.4.11-4 is up to date -- skipping Warning: manjaro-pipewire-20220217-2 is up to date -- skipping Nothing to do. Transaction successfully finished.
But still no sound
I forgot to mention that I do have sound from the audio jack and from the bluetooth. But not from the speakers
youre not the only one with this issue …
post output from:
pacman -Qs pulse
inxi -A gave this:

ls /etc/modprobe.d gave nothing at all
remove the pulse leftovers:
pamac remove pulseaudio-alsa pulseaudio-ctl pulseaudio-qt
then create this file:
and put there this line:
save the file, reboot and test
Your first command gave this:
~ pamac remove pulseaudio-alsa pulseaudio-ctl pulseaudio-qt ✔ Preparing... Checking dependencies... Error: Failed to prepare transaction: could not satisfy dependencies: - removing pulseaudio-qt breaks dependency 'pulseaudio-qt' required by kdeconnect
Should I continue with next commands or I need to uninstall KDE connect (I dont need it)?
if you dont use/need kdeconnect, you can uninstall it … if you use it, keep pulseaudio-qt and remove the 2 other leftovers, then create the file as outlined above, reboot and see if that helped
Done. kdeconnect is gone, followed the 2 commands, rebooted and still no audio.
~ ls /etc/modprobe.d ✔ audio.conf
Something to mention (if is not important I will delete this post): after rebooting, on the desktop pops that Comet Lake PCH-LP CAVS Stereo is muted (with icon), and after 2-3 sec. is gone and in the systray audio is unmuted (75% volume in my case). Maybe conflict in the boot proces itself? Or the problem is with the BIOS/motherboard and the sound is disabled from the beginning?
as mentioned, you are not the only one that has issues with this hardware…
alsamixer, press f6, select your card and check if the speakers are not muted…
then try running this:
sudo alsa force-reload
test speakers, if it doesnt work, try this:
amixer -c0 set 'Master',0 100% unmute amixer -c0 set 'Speaker',0 100% unmute amixer -c0 set 'Headphone',0 100% unmute
I will try with graphics. alsamixer gives:
When pressing F6:
And after choosing default:0 sof-cml… it gives:
Still no audio. But what I see on the 3rd pic - Chip: Intel Kabylake, while I have Cometlake…strange.
And amixer -c0 set ‘Master’,0 100% unmute gives me:
~ amixer -c0 set 'Master',0 100% unmute 1 ✘ amixer: Unable to find simple control 'Master',0
