I just noticed this tonight. When I was playing counterstrike I turned my volume knob all the way down and I could still hear shooting and all the sounds from the game. I tryed it with an mp3 also and I could hear it loud enough to hear the words from the song. I have the Klipsch 4.0 I think, or whatever the ones were before the new amp. Is my volume control screwed up? I have had them less then a year, should I get the control area replaced? This is a very annoying problem, muting them from windows works but I would rather do it form the knob, so I can listen with my headphones.
