There might be interfaces that change the type of connection depending
on the current configuration (clock setting, pluggable hardware modules
In the hdsp(m) and marian drivers I added ports.in and ports.out in
/proc which contain a list with the current physical port names. It is a
quick hack, but it works fine together with a patch for jack that
imports this list.
Machines can do the work, so people have time to think.
