Well its not the actualy front panel connectors, its the connecting. My motherboard NOR my soundcard supports front audio connections. I want to wire up these ports so that it gets the audio signal from the soundcard, and if I plugin my headphones, it shuts off the speakers. I believe this would be possible with like 3 or 4 transistors, but I do not know my gates. Maybe their is a cheap IC for this. Can anyone help me with this? If nobody has any clue I will just wire up a DPDT switch.
