No, I intend that generally only engine pass data from producers to
consumers.
However a producer may ask data to other producer (generally not visible

All is engine driven: i.e. audio is obtained from producer first, then
elaborated and passed to consumers one unit at a time.

All documentation is up-to-date and embedded in source.
You can generate it using:
doxygen doxygen.cfg
in alsa-lib/doc directory (the generated documentation goes in
alsa-lib/doc/doxygen/html)
