Hello guys, if I'm attaching a audio cable to a surround sound model number e290 which is also Sony the problem is when I plug in the cable into headphones jack on the side I loose the sound from the TV speakers I'm assuming is there any setting that I can use so I can listen to surround sound for normal TV channels through the home theater but also get the sound out of my TV without needing to unplug the cable from the headphones?
