Ummm..."phone jack" - if you mean the headphone jack, yes - and rather than the "Y" adapter, I found a commercial-free internet radio station that lets you program your own station, I set the music level at about 50%, set the TD sounds at about 85% and it worked great - a nice level of background music during the tourney, with the TD sounds coming over the top of the music just enough to be clearly heard! - It was a big hit with everyone at the game.
