I seem to be having difficulty coaxing a search engine to find the answer for me, instead getting immediately directed to airport extreme info... Equipment in Room A: Cable Modem connected to Airport Extreme. Equipment in Room B: iMac, with external speakers plugged into the audio out. I would like to be able to share the speakers of the iMac with my MacBook. It would be nice if I could just move the Airport Extreme and Modem to where the iMac is and just use the port, but I can't. How can I set it up so I can play music from my MacBook through the speakers connected to the iMac, which is on the same network, through the audio port? Thank you!
