Believe we are desync'ed here. What the patchset presents catpt vs SOF. /sof/ runs through SOF firmware so it cannot be account as old-implementation. It's a mix of not recommended fw + incorrect sw flow. As old /haswell/ is no more, there is no worrying about catpt deployment - it's your only option. As there is no userspace involved (lack of topology files), base firmware binary remains the same and amixer kcontrols behave 1:1 when compared to its predecessor, compatibility is left intact. That's exactly why we should be explicit in driver selection. Pretty sure hsw/bdw case is still mistakenly addressed to as if it was atom-based platform. Czarek
