Hi all! Does anyone know if it is possible to have simultaneous audio in & out with an iMac? For instance, suppose I have an FM tuner connected to the audio in jack and then connect the output of the iMac to a power amplifier. I've used this arrangement with a PC in the past, but I can't seem to get it to work with my iMac.
I am able to get visual confirmation that the iMac is receiving a signal (analog) from the tuner by looking at "line in" in system preferences/sound, but I can't seem to have the iMac output either the same signal or a digitized version of same simultaneously.
Essentially, I am asking the iMac to act as a quasi-preamplifer, with me using the OS to switch between sources (e.g. input/tuner, iTunes) if you are wondering...
Anyway, I've tried fiddling with this (other than getting very deep into the intimidating-sounding "aggregate device" settings) and am getting nowhere. Can this be done? This question is presently for my C2D iMac 20", but I should have a spankin' new 24" alumniMac on Tuesday...
Thanks!
