I have TV with headphone socket. However tv's speakers get disconnected when I plug in headphone. My requirement is turn headphone jack into auxiliary output so that I can connect amplifier to it. My wife then can listen to TV, I cam listen to TV through amplifier with volume suitable for my years(I have difficulty in hearing clearly) and then both of us are happy! My TV doesn't have Auxiliary output. My earlier TV had one and we used to use this arrangement.
