Do you mean "read _HSW_AUD_STR_DESC_*" by "ping the audio side" above?
No, I mean call into snd-hda-intel before we do the modeset to ask it for what it actually wants to have set up. At least it feels a bit like only reacting to a modeset after it's done leads to confusion. Or maybe we just need to update the register values we want at compute_time instead of doing rwm fun ...

The audio driver calls us, not vice versa...
