Ok, so here is the deal. I got the adapter / cable that I needed to display my MacBook Pro onto my TV through the HDMI hookup. That works just fine. The issue is, when I plug the audio cable into the headphones jack and then plug the red and white wires into my audio input (surround sound), I don't get any sound. I used headphones all the time so I know that the port works, I just can't figure out why I can't get sound to go through my surround sound. I'd like to be able to watch movies and such with a full hook up to my entertainment system and not have to use my MacBook Pro speakers for the audio. Can you please help me out here and let me know what I am doing wrong? It would be much appreciated. Thank you!
