I'm not sure how much voltage the transmitter send out through that jack. If it's too much, it could damage the sound card and possibly the motherboard. That's why I was wondering if they might have a resistor wired into the jack to prevent that much juice from seeping through. I guess I could take a multimeter to the jack that would go to my pc, wiggle the sticks around and see how high it spikes. Compare it to what the sound card specs say that port can handle and go from there...

Did you get my PM?
