The alsa-lib <-> kernel interface is intentionally undocumented. The only officially supported interface to ALSA is via alsa-lib.
- Well, not completely intentional. But we _recommend_ alsa-lib as the

which documentation? i thought that i'd looked at it all and i didnt get a sense of what i needed, did i miss something?
