@Paolo,

The kernel you installed is too old, we integrated Intel's kernel patch to switch to use snd-hda-codec-hdmi instead of soc/codecs/hdac_hdmi.c.

Please update your kernel to Ubuntu-5.3.0-40.32 then redo the test.

And please don't install Ubuntu-5.3.0-41.33, there is some regression in the -41 kernel. And all these issues will be addressed in the -42 kernel.
