I just bought a NUC10i5FNH and installed Ubuntu 21.10 and i don't have sounds. In parameters i can see this ("Sortie fictive" == "Dummy sound"):

screenshot of dummy sound

Note this computer have a HDMI output only.

Sometime (rarely) sound works, and in place of "Dummy sound", i can see HDMI sound output (something like this).

I followed some other answers without success. There is some information :

  • See my answer at askubuntu.com/questions/1365905/… and see if it works for you... even though you don't have a Dell... Report back.

  • When you added the line from my other answer, did you just add the line, or did you modify the existing model= line to change from auto to dell-headset-multi? Did you reboot after?

Surprisingly, after running the program pavucontrol, HDMI sound card is permanently seen. Sound works fine now.
