Still working on it :)

Sound is not working yet, TBH I sent this report to Debian after I
managed to successfully load the drivers and upload the firmware without
further tests, I guess I was just trusting what linux-firmware was
shipping and thought I could solve the problem in the kernel.

Intel developers confirmed that there may be difference in how the
hardware is connected between boards[1], and here is the bug report
about that[2].

So indeed upstream linux-firmware may be incomplete about what it
provides.

I'll report when I know more.

Ciao,
   Antonio
