I'm curious as to how you go about playing audio while you are in-game on PSN and have it come through instead of your microphone. I have been looking online but can't find any guides. I found one for the 360 where you take a 3.5 to 2.5 mm adaptor and plug that into the controller where the microphone port would usually go. However I don't know how to do something similar for the PS3. Anyone know how this is done?
