Hey Patrick thanks for your reply.
Yeah that’s where I am at:
max (iMac) TO soundflower TO airFoil TO macBook
but receiving only on channels 1-2
I wrote to the guys of rougeamoeba to see how feasible is to add a drop-down menu with extra input in airFoil Speaker but haven’t heard from them. Afteral, if you can receive on channels 1 & 2, you should be able to receive form the other too.
If they pull that, NI am still not sure how would that work on an Airport express, we might have to get some ipod Touch in order to install airFoil Speaker in them and its gonna be expensive.
Still looking for other solutions.
