Hi. I asked a question befor about how to add headphones adjustable by my hearing impaired husband, allowing the sound from the internal speaker to be controled and used or muted by the others listening. I got a great answer and plan to try it today but I have a part two question. I have a dvd player and a roku streaming stick connected. Will that connection have to be changed for the other workaround with bluetooth adapter Nd sound bar addition to complete?
