There must be some good diagram there. The ALSA corresponds to the backend of JACK, and it does the actual I/O. > - - Parts of the Alsa HDSP driver that would a priori need changes. The framework for 32bit float is already in the driver core. It's just the card-driver implementation, i.e. pretty dependent on the hardware stuff. > - - Parts of Jack that would a priori need changes. Not much I guess.
