Sorry i didn't answer quicker. It wasn't the controller itself or the wiring, it was the 12V powersupply for the leds. It might have been low quality or defective, but just getting a new powersupply with the right specs, solved the problem. But thank you, for helping anyways.

Hey,
A long time ago I got an LED strip with a controller to put behind the desk, but I rarely use it. When it is turned on it causes my speakers to hum loudly, and when it is just plugged in (not lighting up) it makes a different hum. Only unplugging power from the LEDs helps. I have two sets of speakers connected to my PC, over AUX and displayport. It does not affect my headset though. So it seems it only affects speakers connected to the wall outlet. Plugging any of the speakers into a USB sound card didn't help either. I tried to research it, but my experiences didn't match up with any of what I found. I figured it must be some sort of electrical interference, not sure though. The hum also changes pitch along with the colour of the LEDs.
Any suggestions?

Thank you in advance.
Kim.

My hardware:
Logitech X-530 5.1 Speakers (AUX)
Logitech Z-313 2.1 Speakers (DisplayPort)
Generic LED strip with controller.
I tried using: MoBo onboard sound, USB soundcard and sound over DisplayPort.

Yeah, it's probably electric interference. Just don't use the LED's when your using the speakers or just take them out.

It's clear that it's an issue with the motherboard, so I'd try cleaning it. I'd also check to see if any exposed wires are touching, or if you wired the speakers/LED cables wrong.
