I am actually trying to play Netflix and other streaming sources audio, through to Wiim that is hooked into my amplifier that is connected to my ceiling speakers in the living room so that I can bypass the iMac (turned Linux) built-in speakers. This is a unit, the iMac I setup for my wife to watch video on while she prepare the meals in the kitchen (not far from the living room). I got tired of seeing her watch a movie on her cellphone and figured I could put this older iMac to good use.
