My TV is a TCL which has barebones functionality. It has an AV out port where a 3.5 mm jack fits but it produces poor audio with no way to mess with the volumes. What do I need so the audio of my consoles(PS3, 360) reach my headphones with good quality? Is it a converter? I checked out some of those HDMI converters but if I plug an HDMI cable there then I have no clue how the TV will get video.
