here is my solution try it
first plug av to 3.5mm jack to tv headphone jack..it must be the one with r and l channel,mine is red and white..after plug white av jack to mr and red to ml...then put dvd hts..wait to play and click on menu button on remote(make sure your dvd disk does not have suound on the menu page) play something on tv..i bet you will her audio but quality is not as good since our hts doesnt have aux or hdmi INPUT....NESB
