No sound after installing Manjaro Kde plasma

Hello, I just installed manjaro kde plasma on my huawei Matebook D14 and I can’t point out why there is no sound. I tried to :

  • install pipewire instead of pulseaudio
  • install sof-firmware
  • update all the drivers and bios

Nothing of the above tries succeed.
Here is the information of my laptop :
