The corresponding cpp-file at that line compares against a variable
called "DRIVER_PORT_NUM", which is a constant defined in
"common/JackConstants.h" on line 53 on the github repo. Could that be
the problem?
That's absolutely the problem, but the limit is arbitrary. Feel free to
recompile jackd2 with changed constants in JackConstants.h.
I guess you need to tweak a bunch of other values as well.
PORT_NUM, PORT_NUM_MAX, DRIVER_PORT_NUM (that's per direction),
PORT_NUM_FOR_CLIENT
That should be it.
Play a bit so it matches your setup. Feel free to send a patch.
