    NO Audio from HDMI ports

    Guys, I have a NUC PC that had Ubuntu 23.10, installed from scratch, and everything worked, including the Audio via the HDMI Port.
    After updating it to Ubuntu 24.04, The HDMI Audio stopped working. I've seen reports from other users with the same problem.
    I've already tried to edit the file "/etc/default/grub" and insert the line "intel_iommu=on,igfx_off" in it, but it still doesn't work.



    Additional information follows:

    Code:
    journalctl -b -r | egrep -i "(alsa|sound)"&&echo ""&&pw-metadata&&echo ""&&cat /proc/asound/devices&&echo ""&&cat /proc/asound/hwdep&&echo ""&&cat /proc/asound/pcm'
    
    aplay -l
    
    pactl list modules short
    
    pw-cli ls
    
    alsactl info
    alsactl init
    alsactl store
    maybe some intel driver missing or pipewire audio, for older pulse audio see https://ubuntuforums.org/showthread.php?t=2477166

    for pipewire https://docs.pipewire.org/page_pulse_modules.html

    https://wiki.debian.org/PipeWire

    helvum deb or alsa based GUI or ancient OSS gtk to view or edit controls, but special editions of professional software audiostations are available but should be not needed for some essential configs, but also there could be codecs or driver issue...
