There are two conditions for the SOF driver to be used in a distro:
a) the DSP needs to be enabled (as reported by the pci class info)
b) sound/hda/intel-dsp-config.c needs to contain a quirk to select SOF
over the legacy HDaudio, such as presence of DMIC/SoundWire or a known
vendor DMI.

Traditionally for desktops neither a) nor b) are true, but this is
changing: we will start adding quirks for specific product lines as
requested by OEMs.

Does this answer to your question?
