[SOLVED] No speaker on Lenovo ThinkBook

Hi there,

I've installed Arch on my Thinkbook 14 G6 IRL (i3-1315U Raptor Lake). I Installed Niri as wayland compositor and pipewire, but I've audio issue like there is no audio card on pc. If I plugin usb hearphone audio work well.

That is my aplay -Ll:

null
    Discard all samples (playback) or generate zero samples (capture)
pipewire
    PipeWire Sound Server
default
    Default ALSA Output (currently PipeWire Media Server)
aplay: device_list:279: no soundcards found...

and pactl list sinks:

lspci | grep audio

pipewire, pipewire-pulse and wireplumber service are active and running.

How can I fix it? Tried to roll back to pulse and doesn't work. Doesn't work also using a removable media with Arch and KDE.

EDIT:
I installed sof-firmware and now it work
