I have an iMac and a second monitor. My PS3 is plugged into the second monitor. Is there a way I can have audio come from both the iMac headphone jack and the second monitor jack? Otherwise I have to unplug the stereo and plug it into the other monitor when I want to switch from gaming to working, and it's impossible to have both audio outputs at the same time (if I wanted to listen to music from the imac while still hearing a bit of sound from a game for example). Does anyone know a solution? My research so far hasn't yielded any results. Thanks in advance.
