Comment # 3 on bug 1176351 from Gerald Pfeifer

Thank you, Takashi!

Indeed the sof-firmware package was missing. Once I installed that (and
removed the kernel command-line hack) audio was up and running fine from
what I can tell.

Now, how can we improve the situation for new users?

My notebook (installed from scratch) has 31 kernel-firmware packages
installed, including kernel-firmware-nvidia and kernel-firmware-mellanox
(where neither hardware is present).  I take it sof-firmware is somehow,
hmm, different?

Is there a way to pull in sof-firmware when needed? Or install by default,
like the others?
