I am outputting my audio from my PS3 through the red and white cables that came with it video is HDMI. Anyway, I have the audio going through this little adapter thing where it connects the white and red into a 3.5mm headphone jack so I can use this with my PC speakers. This has been working fine for a long time. Anyway today I decided I wanted to have the audio go through my Macbook Pro. So I just wanted to know if you guys could tell me how to do this. I connected my input (PS3) into he mic port on the MBP and in system preferences it shows it as inputting now what I want to know is if anyone can tell me how to get that audio to come back out from my MBP.
