I have just purchased a Sony Bravia KDL-46X4500. I have connected my MacBook Pro to the TV from the MBP's Mini DisplayPort to HDMI 1 on the back of the TV. I have turned on mirroring and the display is great - but I am getting no sound . I have a 3.5mm to stereo RCA cable. I plugged it into the headphone socket on my MBP. However, I don't know where to plug the other end to play music from the TV speakers rather than the MBP speakers. Can anyone help me with this problem with the Sony Bravia KDL-46X4500?
