I am about to set up my MacBook Pro with my new television so I can watch online shows, movies, and listen to music through my surround system. Currently, my television is set up to have its audio out connected to my surround sound. I was hoping that I could connect an audio in with the HDMI that would connect either directly to the surround sound or through the television into the surround sound. Both have the red and white connections. So, I was wondering how I could connect my MacBook from the one audio output and get it to the two audio inputs (either on my tv or surround sound system).
