To get others the info to help, post a link to that Sony surround system so they know exactly what you have.
My PS3 is connected to my Sony surround sound system via a HDMI cable. My Rogers HD PVR is connected to the surround sound system via a HDMI cable. And my surround sound system is connected to my TV via a HDMI cable. Before I got a surround sound system, I used to plug my headphones into the AUDIO OUTPUT terminal at the back of my TV (the headphones have an audio cable that's permanently attached at one end and has a red plug and a black plug on the other) to enjoy a TV channel or Blu-ray.
How do I connect my headphones so that my wife doesn't have to listen to what I'm watching (she has a problem with gunfire, explosions and other manly things)? I tried leaving them connected to the AUDIO OUTPUT at the back of the TV, turning off the TV speakers and muting the surround sound system speakers, but that didn't work. Neither my TV nor the receiver have a headphone jack, by the way.
