$ aconnect -i
client 130: 'FreeWheeling' [type=user]
    1 'FreeWheeling OUT 1'
    2 'FreeWheeling OUT 2'
    3 'FreeWheeling OUT 3'
    4 'FreeWheeling OUT 4'

$ aconnect -o
client 130: 'FreeWheeling' [type=user]
    0 'FreeWheeling IN 1'

Don't bother about the IN/OUT stuff and numbers that
are part of the human readable names.
Use the 'real' port numbers (the ones at the beginning
of the lines aconnect -io outputs) instead.

The following works for me:

either using the client name string and port numbers
$ aconnect FreeWheeling:1 FreeWheeling:0

or using the the client number and port numbers
$ aconnect 130:1 130:0

I hope this helps.
