No Audio - Manjaro xfce fresh install

Hello, I installed xfce Manjaro in an old computer of mine. I wiped the disk and made a fresh install, but my audio devices (the one of the Motherboard and a sound card attached) don’t work. They don’t even appear in the audio devices, just the dummy audio, any help?

In that case, the inxi output you provided won’t help, and we need some hardware info…

:sob:

In any case, Kernel: 5.9 is EOL so try 5.4 LTS if you have old hardware or 5.10 LTS if you have new hardware instead…
