Hi Mark

These patches add new .dpcm_merged_foramt to merge FE/BE formats. It will be no sound if DPCM were below style, and user selects S24_LE.

FE: S16_LE/S24_LE BE: S16_LE

DPCM will selects FE/BE merged formats (= S16_LE here) if FE has .dpcm_merged_foramt.

Conceptually, you need to refine all FE hw_params with BE's, not only formats.
