I got a lcd monitor hook up to my pioneer deck(2 audio inputs). I use a ps2 to play movies and such. Now my question is when playing a movie I cant "mute" the sound because i still want to listen to music, just need to watch the screen. when i turn on the volume, both my music and the movie is playing at the same time. How can i get just one sound playing at the moment? I could turn off the music and listen to the movie, but what i want is the screen to be playing with no sound and the deck playing songs
