Ask Fedora

I have a new Samsung Galaxy Book 4 with an Intel Core 3 100u cpu.

The device is listed as Intel Raptor Lake-P/U/H cAVS

The audio does not work, with or without headphones (on Fedora).

inxi returns the audio as

Audio:
  Device-1: Intel Raptor Lake-P/U/H cAVS vendor: Samsung Co
    driver: sof-audio-pci-intel-tgl bus-ID: 00:1f.3 chip-ID: 8086:51ca

    status: active 2: wireplumber status: active 3: pipewire-alsa type: plugin

Any ideas?

I installed

alsa-sof-firmware

and it brought the sound.

sudo dnf install alsa-sof-firmware

and reboot.
