Open Sound Firmware maybe missing… Used in a lot of Intel and AMD products, but dropped support for older ones… maybe not required…
sudo apt install firmware-sof-signed
apt show firmware-sof-signed
apt list *firmware* like bluez for bt…
amid common problems in sound issues, there is also option to tune problem in dmesg with some driver with:
lsmod
modinfo snd_hda_intel for issues like this or when some drivers or its some setup(piperwire, rt, preempt) cause some weird behavior on kernel init - journalctl -b
but according some Intel NUC guides, it could be also some UEFI/BIOS settings…
there are also issues with /etc/modprobe.d/alsa-base.conf setup, driver hdmi sound(there is intel kernel driver for that) output and mostly also with index and msi_enable tunables(msi are IRQs enablement) but also maybe mixer failures as longtime issue not only there…
