My setup consists of my macbook with an external LCD monitor with video input. I had an idea: i plugged in my PS2 into my LCD monitor for video, and since there's no audio input on the monitor, i thought i'd run the audio from my PS2 to the audio-in of my macbook. I thought the sound that was fed in, was supposed to playback, but it doesn't. I know there is sound because when i check the sound system preferences, in the input tab i see there's a signal. I guess my question is a probably a fundamental one then, how would i actually be able to hear the sound coming from my PS2? External speakers unfortonately are not part of my setup Any thoughts would be appreciated!
