[Close] Sound Card - no driver (manjaro)

Ok, I use PulseAudio
I recently try the loopback(clue post) function of Pulseaudio (I wanted output sound both in Bluethooth and internal card)
Pulseaudio-control (pavucontrol) just give me a “dummy” as output (thanks)

If i understood well sound-card driver is kernel loaded
So, it’s works or its not. I do a try to :
sudo pacman -S sof-firmware

whoami :

inxi -SA                                                                                                                   ✔  3.2.1 

auto null monitor confirmed here

So I try :

pactl unload-module module-loopback

Nothing, other outputs :

aplay -l

= No sound card found

I dont know what pipewire is doing here…

Maybe audio not have in pulse group clue

cat /etc/group | grep audio
> audio:x:996

I search/try a lot forums.
Here am back home :wink:
tell me if you have a clue for me

Quickly checking my setup on manjaro, it shows as using pipewire:

inxi -SA                                                         ✔

Thanks @lbkNhubert
Here is not :wink:
Ok, I close the Topic…
not solved : I finaly use a recent backup to restore my system.
Rsync is some time better than searching a bug
