I am not suggesting to describe all cards fully. I am saying that if ALSA developers have already implemented SOME commutation, connectivity, gain control, sample rate control, they DO ALREADY KNOW the data necessary to be supplied with/into the proposed HAL. So we, end users, won't have to ask about enabling capture, or gain control, or SPDIFF through, etc, it will be instead in the HAL instance/realization of the card (if the features are implemented, of course), and the (mixer + its GUI) generation application taking that HAL instance will generate the necessary mixer automatically - just for known (i.e. implemented) functionality. The question is whether C++ is good for this (HAL) or some other less strict type language should be used. And, of course, ALSA developers know better than us all what are the real possibilities in cards. ------------------------------------------------------- Using Tomcat but need to do more?
