    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!

    Not a dumb question, but I can't remember. I'll re-rig it and see.

    Brotherman- you rock! Thanks a million for the link. When I am visiting my buddy in Pt. Townsend I'll raise a toast to the lights of Victoria in your honor (I live in Bellingham, btw)...

    Think soft LineIn will be able to output digitally? I will experiment..

    Cheers - let us know if it does the trix. Maybe I'll meet you someday when we go down to Port Townsend for Tango dancing.
