Usually the DSP is not traditionally enabled on H skews but this might be used moving forward.

"This might be used moving forward"?

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?
