Public bug reported:

    Hello,
    I have a brand new Dell XPS 14 (model 9440) running Ubuntu 24.04 LTS. There is no audio output or input device detected, only a "Dummy Output" is available.

    The dmesg log shows the following error:
    sof-audio-pci-intel-mtl 0000:00:1f.3: SOF firmware and/or topology file not found.

    I have already tried the following steps without success:

        Updated the BIOS to the latest version from Dell's website.

        Installed the latest linux-oem-24.04 kernel.

        Manually installed the latest sof-firmware binaries (v2.9) from
the official SOF project GitHub repository into /lib/firmware.

        Tested the snd_hda_intel.dmic_detect=0 kernel parameter.

    The problem persists after all these actions. It seems there is a
kernel driver issue with the new Intel Meteor Lake audio hardware on
this specific laptop model.
