I am having trouble hooking up my power led light on my case to correspond to the music playing. Reason is because this is my living room pc and the light is way to bright and cheesy to always be on. I thought it would be a cool idea to see the light in action with music considering that it would only be on every now and then.
I bought a standard headphone jack splitter to hookup my speakers and provide a feed to the light. It is standard +PWRLED and -PWRLED type of case light. I bought a headphone male to male cable and cut an end off, and stripped the wire. The headphone connector end is hooked up to the splitter along with the speakers which don't sound any different than they did before. There is a black and red wire inside the on cutoff/stripped end. I naturally try to hook them up to the POWERLED wires and no action on the light even with the volume blasted as high as windows will let me.
So I got
Soundcard -> Splitter -> Speakers|Wire going to Power LED.
Current theory is that the audio signal is not providing enough power/watts to make the light illuminate. My Subwoofer plugs ino a standard wall outlet for power. I don't have a multimeter to test it versus the motherboard.
Are you sure you have the LED connected correctly. An LED will only light if the voltage is the correct polarity. Usually the LED wires are either 1 colored wire and 1 black or white wire. The colored wire need to have the positive (+) voltage connected to it.
If that doesn't work then the speaker connection probably can't supply enough power to light the LED.
